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 2.2.0 or better. Do not try to use an older GTK+ version (1.2.x), it will not work. GTK+-2.2 itself needs recent versions of GLib, Pango and ATK. Grab them from ftp://ftp.gtk.org/. GTK+-2.x and friends can be installed side by side with GTK+-1.2. 3. We require PangoFT2, a Pango backend that uses FreeType2. Make sure you have FreeType2 installed before you compile Pango. It can be downloaded from http://www.freetype.org/. 4. We use libart2. Grab the module libart_lgpl out of GNOME CVS or fetch the tarball from ftp://ftp.gnome.org/pub/gnome/sources/libart_lgpl/ 5. You may want to install other third party libraries or programs that are needed for some of the available plugins: tiff, png, jpeg, print, helpbrowser, ... 6. Configure the GIMP by running the `configure' script. You may want to pass some options to it, see below. 7. Build the GIMP by running `make'. The use of GNU make is recommened. If you need to tweak the build to make it work with other flavours of make, we'd appreciate if you'd send us a patch with the changes. 8. Install the GIMP by running `make install'. In order to avoid clashes with an installed stable version of The GIMP, we install a binary called gimp-1.3. Please make sure you don't have any old GTK+-2.x, jpeg, etc. libraries lying around on your system, otherwise configure may 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.x.tar.gz # unpack the sources % cd gimp-1.3.x # 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: --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. --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. --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. --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. --without-libtiff, --without-libjpeg, --without-libpng. configure will bail out if libtiff, libjpeg or libpng can not be found. You better fix the underlying problem and install these libraries with their header files. If you absolutely want to compile GIMP without support for TIFF, JPEG or PNG you need to explicitely disable them using the options given above. --without-exif. If libexif is available, the JPEG plug-in will use it to keep EXIF data in your JPEG files intact. If this is causing any trouble at compile-time, you can build --without-exif. Get libexif from http://www.sourceforge.net/projects/libexif. --without-mng, --without-aa. The MNG plug-in needs libmng and configure checks for its presense. If for some reason you don't want to build the MNG plug-in even though the library is installed, use --without-mng to disable it expliticely. The same switch exists for aalib, use --without-aa if you run into problems. --with-gif-compression=[lzw|rle|none]. Allows to tune the compression algorithm used by the GIF plug-in. If you are afraid of Unisys' LZW patent, you can go for simple run-length encoding or even configure the plug-in to create uncompressed GIFs. --enable-gtk-doc. This option controls whether the libgimp API references will be created using gtk-doc. The HTML pages are included in a standard tarball, so you will only need this if you are building from CVS. --with-html-dir=PATH. This option allows to specify where the libgimp API reference should be installed. You might want to modify the path so it points to the place where glib and gtk+ installled their API references so that the libgimp reference can link to them. --disable-print. The print plug-in requires a recent version of libgimpprint. If you don't have it already installed, download it from http://gimp-print.sourceforge.net/. You need to pass --without-gimp to gimp-print's configure script to build it without having gimp-1.2 installed. If you want to compile GIMP without support for printing, use the --disable-print option. --enable-mp. This options control whether to build GIMP with or without support for multiple processors. This option is 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. --with-sendmail=[PATH]. This option is used to tell GIMP where to find the sendmail command. Normally this options don't have to be used because configure tries to find it in the usual places. --with-desktop-dir=[PATH]. This option specifies where to install links to the gimp desktop files. These files are used by desktop environments that comply to the specs published at freedesktop.org. The default value ${prefix}/share should be fine if your desktop environment is installed in the same prefix as gimp. No links are created if the desktop directories don't exist or you used --without-desktop-dir. --enable-default-binary. Use this option if you want to make gimp-1.3 the default gimp installation. A link called gimp pointing to the gimp-1.3 executable will be installed then. The `make' command builds several things: - A bunch of public libraries in the directories starting with 'libgimp'. - The plug-in programs in the 'plug-ins' directory. - Some modules in the 'modules' subdirectory. - The main GIMP program 'gimp-1.3' in `app'. The `make install' commands installs the gimp header files associated with the libgimp libraries, 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'. 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. A detailed log of the ./configure output is written to the file config.log. This may help diagnose problems. 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. 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'.
