Hello,

after a while of searching and some trial and error, I managed to compile the latest git version of GIMP on Snow Leopard (with 64bit kernel enabled). Since I didn't find a tutorial treating this particular subject I have written one and posted it here : http://clockwork.fr/how-to-compile-gimp-271-on-snow-leopard/

I was wondering whether anybody would have suggestions on how to improve on this process, especially on the two mac-specific problems (the twain compilation problem and the odd behavior of linking against libjpeg)

Just to be more specific about these issues :

when I tried to compile GIMP without installing libjpeg from source (and thus into /usr/local/lib) it complained about not being able to find the library even though other libraries (like glib, gtk or tiff) didn't seem to have problems. I did add the correct -I and -L flags to CFLAGS and LDFLAGS variables

for the twain i join the compiler output at the end of this message, since I don't have a scanner I found it easier to just disable it by force

Finally, I'd be more than happy to create an application bundle if someone could point me to a good tutorial on howto create those. (if there is a point of a bundle for the development release)

Sincerly Jozef

Please be more specific and send us information about how exactly you call ./configure and what the exact error is (including the relevant parts from config.log).

The call to configure I use is :

./configure --prefix=/opt/gimp-2.7 --disable-mmx

and the resulting error is

checking for jpeg_destroy_decompress in -ljpeg... yes checking for jpeglib.h... no (Can't include jpeglib.h) configure: error:
*** Checks for JPEG library failed. You can build without it by passing *** --without-libjpeg to configure but you won't be able to use JPEGs then.

The relevant part from config.log is :

I do, however, have jpeglib.h in /opt/local/include folder (just where libtiff, which works, is). When I install libjpeg to /usr/local/lib the problem solves itself.

Just out of interest, are you building against GTK+ compiled with the native Quartz backend or are you still using X11 for this?

As for the GTK+, I'm using the X11 version. I also tried compiling stable GIMP with the GTK+ with Quartz backend using MacPorts (and succeeded), however text was displayed incorrectly (squares instead of characters). I've tried to find a way to solve this issue (probably coming from quartz backend for pango) but was unsuccessful.

I will try to recompile GTK+ again with the Quartz support, but I need to find a way to isolate it from the rest of my environment since I do need functional GTK+ on daily basis.

Well, did you add -I/opt/local/include to CPPFLAGS before calling the configure script?

Actually, I didn't, just tried it and it worked. Thank you.
