For pre-built binary packages of GLib, GTK etc, see http://www.gimp.org/win32/downloads.html . No pre-built GIMP 1.3 packages, though. Building GIMP on Win32 ====================== There are two ways to build GIMP on Win32: 1) Use the autoconf-generated configure script, and the resulting Makefiles (which use libtool and gcc to do the compilation). I use this myself. Unfortunately, this doesn't work 100% correctly in all directories. For instance in plug-ins/common there is some problems with the optional plug-ins, for instance "png". The generated Makefile wants to make just png (no .exe), and then tries to compile it without any of the relevant -I and -D flags, which of course fails. You have to explicitly make png.exe. 2) Use the Microsoft compiler, cl and Make, nmake. Say nmake -f makefile.msc in various directories. These makefiles are maintained by Hans Breuer . They presumably will not generate the same name DLLs and import libraries as the autoconfiscated libtool build does, nor necesarily use the same named GLib, GTK etc import libraries as those distributed from the web site mentioned above. --Tor Lillqvist
