Given that you seem to be using old versions of everything, is this 'gtk' actually from the gtk-1.2 series ? If so, most people stopped trying to build that a long time ago. And, again if the versions are old - what are you building on (distro, CPU, and particularly your versions of binutils or equivalent,, cc and g++, libc ? I'm asking because I think most peopel here cannot remember details from old versions. But, one general point which will perhaps help - if you have to pass PKG_CONFIG_PATH make sure it is a series of paths which include everything that configure might be looking for which is NOT in /usr/lib/pkgconfig or /usr/share/pkgconfig. The fact you seem to have specified one Xorg lib in a different place makes me think that you have already build what you consider to be enough of xorg to satisfy this verison of gtk, and usually there will be more than one library with a .pc file! ĸen -- (Rincewind) was pretty sure there was no way you could get a cross between a human and a sheep. If there was, people would definitely have found out by now. -- The Last Continent
