Quick start ============== This document gives basic and detailed instructions on how to compile and install the source distribution of POV-Ray for UNIX/Linux. It is intended to those already familiar with compiling and installing programs on UNIX platforms using the GNU build system. Compiling and installing POV-Ray from sources is achieved by running the usual 'configure' and 'make' commands. For a system-wide installation: ./configure COMPILED_BY="your name " [options] make check sudo make install The COMPILED_BY argument to 'configure' is mandatory and must be filled with your name and/or organization in case you intend to distribute the unofficial executable you are about to generate. Please refer to the POV-Ray Source License for details. Additional configure options are described in section 4 of this document. The 'make' command builds the program once it is configured. The optional 'check' argument allows to run a short test render after POV-Ray is compiled and before it is installed with 'make install' (see below). Other options are listed in section 3. The last command in the example above installs POV-Ray under system-wide directories and needs root privileges. Installing as non-privileged user is also possible; see section 3.1. By default (i.e. as root), 'make install' installs the following components: povray binary (executable) in /usr/local/bin data files (e.g. includes, scene files) in /usr/local/share/povray-3.7 documentation (text and html) in /usr/local/share/doc/povray-3.7 configuration files (e.g. povray.conf) in /usr/local/etc/povray/3.7 The configuration files are also copied under the $HOME/.povray/3.7 directory of the user (or root) who is doing the installation. For further details regarding those files, please read the instructions in README.unix and in chapter 1 of the documentation. ======================== 2. Software requirements ======================== Building POV-Ray on a UNIX platform requires a relatively modern C++ compiler, the 'make' utility, a Bourne-compatible shell (e.g. bash), and several support libraries. 2.1 Environment =========== The build system must have: - a modern C++ compiler which supports C++ templates and follows the ISO C++ standard as much as possible; for instance, the GNU GCC 4.x series and the Intel C++ compiler version 9.x or above. They are available at: http://www.gnu.org/software/gcc http://www.intel.com/software/products/compilers - a working 'make' utility. We strongly recommand to use GNU Make version 3.79 or above. Most GNU/Linux distribution should come with it. Other platforms should install it before running configure. GNU make can be found at: http://www.gnu.org/software/make - in the unlikely case you don't have a Bourne-compatible shell installed on your system or that the shell fails running POV-Ray's configure, it is recommanded to install GNU bash first. Download it at: http://www.gnu.org/software/bash 2.2 Required support libraries ========================== The following external libraries are required to build a fully-featured POV-Ray executable. The Boost libraries are in general not installed on most systems; several Linux distributions offer Boost through their package repositeries -- please check out there first. The image libraries are relatively standard and should be automatically detected at least on most Linux-based systems. Be sure to have not only the run-time libraries but also the development packages (header files in particular). - Boost version 1.37 or above http://www.boost.org - Zlib version 1.2.1 or above http://www.zlib.net - LibPNG version 1.2.5 or above http://www.libpng.org - LibJPEG version 6b or above http://www.ijg.org - LibTIFF version 3.6.1 or above http://www.libtiff.org 2.3 Optional libraries ================== These additional libraries are not mandatory to build POV-Ray but are recommanded to generate a fully-featured POV-Ray executable. - OpenEXR version 1.2 or above http://www.openexr.com - SDL version 1.2 or above (used for the display preview) http://www.libsdl.org ==================================================== 3. Configuring, building, and (un)installing POV-Ray ==================================================== Configuring POV-Ray prepares the source package to generate an executable for your particular machine and environment, and allows to change the default paths where the program and its accompanying documentation and data files are installed. Using default installation directories requires to install POV-Ray as root; this is the recommanded method if you have the choice. Otherwise, POV-Ray can be installed anywhere one has write access to. 3.1 Building and installing ======================= 3.1.1 As root ------- Configure POV-Ray for building and installing in standard directories: ./configure COMPILED_BY="your name " make check # build the program (binary) and run a test render sudo make install # install everything in the /usr/local hierarchy Here, these commands are ran in the source directory of POV-Ray (but this is not required, see section 3.1.3 below). Note that the COMPILED_BY argument is mandatory. The 'check' target for 'make' may be omitted (no test render is performed) in particular when building POV-Ray in batch. The top Makefile generated by configure supports the following targets: make # build the program make check # (build and) perform of short test render make clean # clean all object files created by make make dist # create distributions in .tar.gz & .tar.bz2 formats make dist-bzip2 # create distribution in .tar.bz2 format only make dist-gzip # create distribution in .tar.gz format only make distcheck # create and check (build) a distribution make distclean # clean all files created by configure and make make install # (build and) install the program, data, and docs make maintainer-clean # caution: maintainers only (see Appendix A) make uninstall # uninstall the program, data, and docs 3.1.2 As non-privileged user ---------------------- Without root priviledges, POV-Ray may be configured for installation under an alternate hierarchy (e.g. /some/path) where one has write access to: ./configure --prefix=/some/path COMPILED_BY="your name " make check install The compilation, test render, and installation are invoqued using a single 'make' command. All make targets listed in the section above are supported when building POV-Ray as a regular user. The test render may be skipped by invoquing 'make install' instead. For test purposes, POV-Ray may also be compiled without installing: ./configure COMPILED_BY="your name " make check # or 'make' to skip the test render The povray executable is then located under the unix/ directory of the build tree. The program will keep searching for its configuration files under the /usr/local hierarchy. Note that compiling POV-Ray without installing is NOT the recommanded way as it complicates the normal usage of the program (e.g. to access POV-Ray's standard include files). 3.1.3 Building in-place or elsewhere ------------------------------ As presented above, the configure command is ran from the source directory of POV-Ray. This is commonly referred to as building the package "in-place". It is also possible (and often recommanded) to build the platform-specific object files and executable in a different location. The source tree thus remains unchanged; this is useful especially in the case of read-only distribution media (such as CDs). For instance: mkdir -p /tmp/build/povray && cd /tmp/build/povray /path/to/configure COMPILED_BY="your name " [options] make check install Doing so creates a mirror of the POV-Ray source hierarchy (the build tree) under the /tmp/build/povray directory. All Makefiles and platform-specific object files as well as the povray executable are created therein. 3.1.4 Cross-compiling POV-Ray ----------------------- Cross-compiling is the procedure by which a compiler running on one system produces executables for another system. Cross-compiling is important in particular when the target system doesn't have a native set of compilation tools. Such a situation can happen for instance with embedded systems. While the configure script for POV-Ray has been written with this concept in mind, it has not been much tested in a cross-compiling environment. Thus, it is likely that the configure script will fail in this particular context. If you have any experience in setting up a cross-compiling toolchain and are able to test POV-Ray's configure with it, you are welcome to report any success or patches on the povray.unix newsgroup (news.povray.org). 3.2 Uninstalling POV-Ray ==================== Regardless of the way POV-Ray was installed (as root or as non-privileged user), the program, documentation, configuration and data files may be uninstalled by running: make uninstall in the main source directory of POV-Ray (or in the build directory where the package has been configured, see section 4.1.3). Only those files and directories that were created by the installation procedure are removed. Note that the uninstall procedure will only work when: (a) you have write access to the directory where POV-Ray is installed, and (b) POV-Ray has not been re-configured in between the 'make install' and 'make uninstall' commands using another --prefix path. =============================== 4. Additional configure options =============================== More options can be passed to POV-Ray's configure in order to tweak the configuration process to specific needs. The full list of supported options is displayed with: ./configure --help A shorter list is displayed with: ./configure --help=short 4.1 Generic configure options ========================= The list below describes the generic configure options that might be the most relevant when building POV-Ray from sources: --prefix=PREFIX allows to install the package under PREFIX. You must have write access to the PREFIX directory. The package is installed under the PREFIX/bin, PREFIX/etc, PREFIX/man, and PREFIX/share directories. --with-x (default) or --without-x requests to use the X Window System (when possible) or not. The X Window System allows to display the image POV-Ray is rendering in a seperate graphics window. In order to use the X Window System, the POV-Ray binary is linked with the X11 library installed on your system. CXX="C++ compiler (path)name" CXXFLAGS="C++ compiler flags" LDFLAGS="linker flags" LIBS="additional libraries to link with" allows to specify which C++ compiler to use and the corresponding compiler and linker flags, instead of those detected by configure. For instance, if one wants to use the Intel C++ compiler instead of GCC and a safe optimization mode, one can type (the COMPILED_BY argument is omitted for clarity): % ./configure CXX=icpc CXXFLAGS="-O2" Here, the -O2 compiler option will not override the list of optimization options that configure will detect, but will be appended to this list (effectively replacing any -O option set previously). In case no other optimization flags are wanted, use the --disable-optimiz option described in the next section. The LDFLAGS are meant to be used for the linker only. Using this option should be useful in only very rare cases (if any). LIBS can be used to specify extra libraries for POV-Ray to link with, for example: LIBS=-ljunk or LIBS=/usr/local/lib/libjunk.a . Using this option is usually not necessary, but might be useful in some very specific cases (see e.g. the --enable-static option below). 4.2 POV-Ray specific configure options ================================== Additional POV-Ray specific options are: --with-boost=DIR requests to find the Boost library in the DIR directory. Boost 1.36 or above is mandatory to build POV-Ray. --with-boost-thread=special-lib requests to find the Boost thread library under the special-lib name, for instance --with-boost-thread=boost_thread-gcc-mt if the thread library is libboost_thread-gcc-mt.a (static form) or libboost_thread-gcc-mt.so* (shared form) under the DIR directory specified by the option above. --with-zlib=DIR or --without-zlib requests to find the ZLIB library in the DIR directory, where DIR is for instance /path/lib if ZLIB is /path/lib/libz.a (static form) or /path/lib/libz.so* (shared form). On 64-bit systems, one may have to specify e.g. /path/lib64 instead. The library headers are assumed to be located under the DIR/../include directory. The --without-zlib option must be used together with NON_REDISTRIBUTABLE_BUILD (described below) in order to disable all POV-Ray features requiring this library. --with-libpng=DIR or --without-libpng requests to find the PNG library in the DIR directory. Further details are given in the related --with-zlib option above. --with-libjpeg=DIR or --without-libjpeg requests to find the JPEG library in the DIR directory. Further details are given in the related --with-zlib option above. --with-libtiff=DIR or --without-libtiff requests to find the TIFF library in the DIR directory. Further details are given in the related --with-zlib option above. --with-openexr=DIR or --without-openexr requests to find the OpenEXR library in the DIR directory, or to disable all POV-Ray features requiring this library. DIR is e.g. /path/lib or /path/lib64. The library headers are assumed to be located under the DIR/../include directory. --with-libsdl=DIR or --without-libsdl requests to find the SDL library in the DIR directory, or to disable the preview display that uses this library. DIR is for instance /path/lib or /path/lib64. The library headers are assumed to be located under the DIR/../include directory. BETA: support for libSDL is required for the preview display but will become optional in the final source release. --with-libmkl=DIR or --without-libmkl requests to use the Intel(R) Math Kernel Library (in directory DIR). BETA: this option is not properly working yet. --with-cygwin-dll (default) or --without-cygwin-dll on the Cygwin platform, requests to link with the Cygwin DLL or not. The --without-cygwin-dll option allows to build an executable that should work on any Cygwin release. It requires having the MinGW tools (Minimalist GNU for Windows, http://www.mingw.org) installed on your machine. You might also use the --disable-shared option with it; see below. BETA: support for the cygwin environment hasn't been tested much. --enable-watch-cursor enables the mouse pointer to show up as a watch cursor over the X Window display while rendering the image. --enable-debug enables compiler debugging mode, i.e. ask the compiler to insert debug information within the executable that is useful for a debugger such as GDB (http://www.gnu.org/software/gdb). The debugging mode dramatically increases the size of the generated executable and may also make it run slower. It is therefore only meant for developers who want to experiment with the source code. For best results, it is often recommended to disable all compiler optimizations; see below. --enable-profile enables execution profiling, i.e. ask the compiler to generate run-time information that details in which parts of the code the program spends most of the CPU time. This mode is targeted at developers who are willing to experiment with the code. Using this mode requires debug information in the binary, so configure automatically turns on --enable-debug when --enable-profile is used. --enable-static or --disable-shared disables linking with shared libraries, i.e. the POV-Ray executable will include all the machine code corresponding to its own source as well as that of the libraries it uses. This option thus allows to generate a "static" binary that has no dependency to any system-specific library. Obviously, the size of the executable increases dramatically. Using this option is preferred to redefining LDFLAGS, as configure will try to guess and test what option the linker really needs to link with the static (rather than the shared) libraries. Note: Some platforms (e.g. several GNU/Linux distributions, Solaris) can not statically link the X11 library with POV-Ray for various reasons, and might either disable support for the X Window display or cause a linkage error. In the first situation, it might be required to pass additional libraries to the linker, e.g. LIBS=-ldl (the exact libraries can be guessed by inspecting the config.log file). In the second situation, specify --without-x or do not use the present option. --disable-optimiz disables all compiler optimizations, i.e. configure will not try to set any optimization flags suitable for your system. This option is useful in particular together with specifying CXXFLAGS. --disable-optimiz-arch disables only the architecture-specific compiler optimizations. Generic optimization flags such as "-O3" are still detected and used. --disable-pipe disables the use of pipes for communication between the various stages of compilation, and use temporary files instead. This is slower, but on some systems pipes cannot work properly. --disable-strip disables the compiler to strip all symbols from the object files, which results in a much larger executable. This option is only useful when specifying the debugging and/or profiling mode described above. --disable-io-restrictions disables all file input/output restrictions, meaning that POV-Ray will never try to check whether it is allowed or not to perform file and/or shellout operations. For more details about I/O restrictions, please refer to chapter 1 of the documentation. Use this option at your own risk. COMPILED_BY="your name " this option is required when configuring the source package. Please provide with a valid contact information that will be included in the executable and displayed whenever POV-Ray (or a modified version) is started. NON_REDISTRIBUTABLE_BUILD=yes this option must be used in case one needs to build POV-Ray without support for a particular image library, i.e. together with any of the --without-zlib, --without-libpng, --without-libjpeg or --without-libtiff options. Using this option means you acknowledge that the generated POV-Ray executable must *not* be redistributed. C99_COMPATIBLE_RADIOSITY={1,2,3,4} adapts the POV-Ray radiosity code to use non-IEEE 754 floating point on machines that do not support this standard. You must specify one of the possible values given above (e.g. C99_COMPATIBLE_RADIOSITY=2). Each value corresponds to the C function 'logbf', 'ilogbf', 'logb', and 'ilogb', respectively, to be used with the C function 'copysign'. This option requires having an ISO C99 compiler and its accompanying C library installed on your machine. More details are given near the top of the octree.cpp source file. On platforms where integer ('int') and single-precision floating-point ('float') numbers are not 32-bit, configure will try to determine automatically which function to use. ================= 5. Reporting bugs ================= In case POV-Ray's configure or any part of the compilation/installation fails on your system, please report the problem(s) on the povray.beta-test newsgroup (news.povray.org) with the mention "[unix]" in the post title. Please try to be as specific as possible in describing the problem. If POV-Ray was otherwise built but fails to run for some reason, please report the output of the "povray --version" command (without quotes) along with the description of the problem.
