To whom it may concern: If this email should be sent instead to the gimp-user list, please let me know and I can send it there. I attempted to compile the Gimp, version 1.2.3, (on a linux 2.4.14 machine) under X 4.0.2, and got the following error: <output> gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../intl -I/opt/gnome/include/gtk-1.2 -I/opt/gnome/include/glib-1.2 -I/opt/gnome/lib/glib/include -I/usr/X11R6/include -I/usr/local/include -DLIBDIR=\""/usr/local/lib/gimp/1.2"\" -DLOCALEDIR=\""/usr/local/share/locale"\" -DREGEX_MALLOC -DG_LOG_DOMAIN=\"Gimp\" -DGTK_DISABLE_COMPAT_H -g -O2 -Wall -c text_tool.c In file included from /opt/gnome/include/gtk-1.2/gdk/gdkx.h:30, from text_tool.c:28: /opt/gnome/include/gtk-1.2/gdk/gdkprivate.h:31: X11/Xlib.h: No such file or directory /opt/gnome/include/gtk-1.2/gdk/gdkprivate.h:32: X11/Xutil.h: No such file or directory make[2]: *** [text_tool.o] Error 1 make[2]: Leaving directory `/home/john/download/gimp-1.2.3/app' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/john/download/gimp-1.2.3' make: *** [all-recursive-am] Error 2 </output> I was unable to find the two header files that the compilation choked on, and so my best guess is that X 4 rearranged the location (and possibly API) of their header files. Or it could be some other thing entirely which I'm doing wrong. If you need any further information, please let me know. I'm not (yet?) on the mailing list, so I would appreciate a cc:, if at all possible. Thanks (for this and for a great product), John L. Clark
