THIS IS A DEVELOPMENT VERSION OF THE GIMP !! YOU SHOULD BE USING THE STABLE VERSION 1.2 INSTEAD !! YOU HAVE BEEN WARNED! There are some basic steps to building and installing the GIMP: 1. You need to have installed a recent version of pkg-config available from http://www.freedesktop.org/software/pkgconfig/. 2. You need to have installed GTK version 1.3.7 or better. Do not try to use the stable GTK+ versions 1.2.x, it will not work. GTK+-1.3.x are development releases of the upcoming GTK+-2.0 release. GTK+-2.0 itself needs recent versions of GLib-2.0, Pango and ATK. GTK+-2.0 and friends can be installed side by side with GTK+-1.2. 3. You may want to install other third party libraries or programs that are needed for some of the available plugins: TIFF, PNG, JPEG, MPEG, perl, etc. 4. You may want to install the freefont package so you have the fonts most scripts use by default. Grab it from ftp://ftp.gimp.org/pub/gimp/fonts/ 5. Configure the GIMP by running the `configure' script. You may want to pass some options to it, see below. 6. Build the GIMP by running `make'. 7. Install the GIMP by running `make install' or `make install-strip'. 8. Optionally install the separate gimp-data-extras package. Please make sure you don't have any old GTK+-2.0, jpeg, etc. libraries lying around on your system, otherwise configure will fail to find the new ones. Generic instructions for configuring and compiling auto-configured packages are included below. Here is an illustration of commands that might be used to build and install the GIMP. The actual configuration, compilation and installation output is not shown. % tar xvfz gimp-1.3.0.tar.gz # unpack the sources % cd gimp-1.3.0 # change to the toplevel directory % ./configure # run the `configure' script % make # build the GIMP % make install # install the GIMP The `configure' script examines your system, and adapts the GIMP to run on it. The script has many options, some of which are described in the generic instructions included at the end of this file. All of the options can be listed using the command `./configure --help'. There are five commands special options the GIMP `configure' script recognizes. These are: 1. --enable-shared and --disable-shared. This option affects whether shared libraries will be built or not. Shared libraries provide for much smaller executables. The default is to enable shared libraries. Disabling shared libraries is almost never a good idea. 2. --enable-debug and --disable-debug. This option causes the build process to compile with debugging enabled. If debugging is disabled, the GIMP will instead be compiled with optimizations turned on. The default is for debugging to be disabled. NOTE: This option is intended primarily as a convenience for developers. 3. --enable-ansi and --disable-ansi. This option causes stricter ANSI C checking to be performed when compiling with GCC. The default is for strict checking to be disabled. NOTE: This option is intended primarily as a convenience for developers. 4. --enable-gimpdir=DIR. This option changes the default directory the gimp uses to search for its configuration files from ~/.gimp-1.3 (the directory .gimp-1.3 in the users home directory) to DIR. 5. --enable-perl and --disable-perl. The perl extension does not build on all systems. If you experience problems use --disable-perl and gimp will not even try to built it. The perl extension does not usually respect the normal configure prefix but uses perl's instead. You can force it to use a different prefix by giving it as an argument to the --enable-perl option (--enable-perl=/my/prefix), however, you will usually have to set PERL5LIB or equivalent environment variables, otherwise gimp-perl will not run or you will get many errors on startup. See README.perl for even finer grained control about installation paths (and distribution making). 6. --enable-nls and --disable-nls. This option changes whether to build GIMP with or without localisation support. This option is enabled by default. If you'd like to enjoy GIMP in your native language, assuming the necessary catalogs are available, then leave this option on. If you'd like to have an English GIMP in every case then turn this option off; this will also decrease the binary size by a few bits. 7. --with-threads and --with-mp. This options control whether to build GIMP with or without support for multiple processors. This options are off by default. If you do have multiply processors and run GIMP with an OS supporting them you will like to enable this features to use all of your horsepower. Enabling it on singleprocessor systems won't harm but cause a bit processing overhead. 8. --with-sendmail=[]. This option is used to tell GIMP where to find this command. Normally this options don't have to be used because configure tries to find it in the usual places. 9. --enable-python and --disable-python. This options control whether to build the python scripting language plygin or not. This options defaults to off. The `make' command builds several things: - The libraries `libgimp/libgimp.la', `libgimp/libgimpi.la' and `libgimp/libgimpui.la'. The `.la' suffix is used by libtool, the program used to ease the compilation of shared libraries on different platforms. - The plug-in programs in the `plug-ins' subdirectory. - The main GIMP program in `app/gimp'. The `make install' commands installs the gimp header files associated with libgimp and the libgimp library, the plug-ins, some data files and the GIMP executable. After running `make install' and assuming the build process was successful you should be able to run `gimp'. Using `make install-strip' will remove unneeded debugging cruft and unused functions from the binaries which will reduce the size of the GIMP and its plug-ins. When ./configure fails ====================== 'configure' uses pkg-config, a tool that replaces the old foo-config scripts. The most recent version is available from http://www.freedesktop.org/software/pkgconfig/ 'configure' tries to compile and run a short GTK program. There are several reasons why this might fail: * pkg-config could not find the file 'gtk+-2.0.pc' that gets installed with GTK. (This file is used to get information about where GTK+ is installed.) Fix: Either make sure that this file is in the path where pkg-config looks for it (try 'pkg-config --debug' or add the location of gtk+-2.0.pc to the environment variable PKG_CONFIG_PATH before running configure. * The GTK libraries were not found at run time. The details of how to fix this problem will depend on the system: Fix: On Linux and other systems using ELF libraries, add the directory to /etc/ld.so.conf or to the environment variable LD_LIBRARY_PATH, and run 'ldconfig'. On other systems, it may be necessary to encode this path into the executable, by setting the LDFLAGS environment variable before running configure. For example: LDFLAGS="-R/home/joe/lib" ./configure or LDFLAGS="-Wl,-rpath -Wl,/home/joe/lib" ./configure * An old version of the GTK libraries was found instead of your newly installed version. This commonly happens if a binary package of GTK was previously installed on your system, and you later compiled GTK from source. Fix: remove the old libraries and include files. * The perl extension does not detect all combinations of libraries and packages it needs to built properly, causing compilation to stop prematurely. Fix: use configure with the "--disable-perl" switch or install perl (version>=5.005) and the Perl-Gtk-interface. A detailed log of the ./configure output is written to the file config.log. This may help diagnose problems. If you are sure of what you're doing, you can bypass the sanity check and just go by what gtk-config by using the --disable-gtktest option. Please only use this in dire circumstances. After fixing a problem, it is safest to delete the file 'config.cache' before re-running ./configure. When ./configure fails on plug-ins ================================== There are some GIMP plug-ins that need additional third-party libraries installed on your system. For example to compile the plug-ins that load and save JPEG, PNG or TIFF files you need the related libraries and header files installed, otherwise you'll get a message that plugin xyz will not be build. If you are sure that those libraries are correctly installed, but configure fails to detect them, the following might help: Set your LDFLAGS environment variable to look for the library in a certain place, e.g. if you are working in a bash shell you would say: export LDFLAGS="-L -L" before you run configure. Set your CPPFLAGS environment variable to look for the header file in a certain place, e.g. if you are working in a bash shell you would say: export CPPFLAGS="-I -I" before you run configure. It's wise to remove the file 'config.cache' before re-running configure. Generic Instructions for Building Auto-Configured Packages ========================================================== To compile this package: 1. Configure the package for your system. In the directory that this file is in, type `./configure'. If you're using `csh' on an old version of System V, you might need to type `sh configure' instead to prevent `csh' from trying to execute `configure' itself. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation, and creates the Makefile(s) (one in each subdirectory of the source directory). In some packages it creates a C header file containing system-dependent definitions. It also creates a file `config.status' that you can run in the future to recreate the current configuration. Running `configure' takes a minute or two. To compile the package in a different directory from the one containing the source code, you must use GNU make. `cd' to the directory where you want the object files and executables to go and run `configure' with the option `--srcdir=DIR', where DIR is the directory that contains the source code. Using this option is actually unnecessary if the source code is in the parent directory of the one in which you are compiling; `configure' automatically checks for the source code in `..' if it does not find it in the current directory. By default, `make install' will install the package's files in /usr/local/bin, /usr/local/lib, /usr/local/man, etc. You can specify an installation prefix other than /usr/local by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for machine-specific files and machine-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Normally, all files are installed using the same prefix. `configure' ignores any other arguments that you give it. If your system requires unusual options for compilation or linking that `configure' doesn't know about, you can give `configure' initial values for some variables by setting them in the environment. In Bourne-compatible shells, you can do that on the command line like this: CC='gcc -traditional' DEFS=-D_POSIX_SOURCE ./configure The `make' variables that you might want to override with environment variables when running `configure' are: (For these variables, any value given in the environment overrides the value that `configure' would choose:) CC C compiler program. Default is `cc', or `gcc' if `gcc' is in your PATH. INSTALL Program to use to install files. Default is `install' if you have it, `cp' otherwise. INCLUDEDIR Directory for `configure' to search for include files. Default is /usr/include. (For these variables, any value given in the environment is added to the value that `configure' chooses:) DEFS Configuration options, in the form '-Dfoo -Dbar ...' LIBS Libraries to link with, in the form '-lfoo -lbar ...' If you need to do unusual things to compile the package, we encourage you to teach `configure' how to do them and mail the diffs to the address given in the README so we can include them in the next release. 2. Type `make' to compile the package. 3. Type `make install' to install programs, data files, and documentation. 4. You can remove the program binaries and object files from the source directory by typing `make clean'. To also remove the Makefile(s), the header file containing system-dependent definitions (if the package uses one), and `config.status' (all the files that `configure' created), type `make distclean'. The file `configure.in' is used as a template to create `configure' by a program called `autoconf'. You will only need it if you want to regenerate `configure' using a newer version of `autoconf'.
