I recently installed Slackware64-14.0 on my new laptop. I'm using Xfce 4.10 as my DE, and I would like to compile some additional programs for my desktop. I first ran into this trouble when trying to compile Tilda terminal from a SlackBuild script I got from SBo:
gcc -DLOCALEDIR=\"/usr/share/locale\" -DDATADIR=\"/usr/share\" -DHAVE_CONFIG_H -I. -I.. -pthread -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -O2 -fPIC -MT tilda-callback_func.o -MD -MP -MF .deps/tilda-callback_func.Tpo -c -o tilda-callback_func.o `test -f 'callback_func.c' || echo './'`callback_func.c
In file included from ./tilda_window.h:21:0,
./tilda_terminal.h:22:21: fatal error: gtk/gtk.h: No such file or directory
So it seems the headers are missing? I have three GTK toolkits installed (versions 1.2.10, 2.24.10 and 3.4.4). configure script did not complain that the GTK2 wasn't there. The headers seem to be present:
> locate gtk.h | sort
I googled some suggestions that my installation of GTK2 may be corrupted. I did "slackpkg reinstall gtk+2", but the problem persists. What's more, I noticed the same thing when trying to compile gpicview: compilation stops with an error regarding missing gtk.h.
I'm quite confused and have no idea what is missing. Could anyone assist me in finding a solution?
