When i try to compile an application, with the ./configure command i get an error message about the pkgconfig can not find the gtk+-2.0 and the other g lib. files. i have the gtk+ and the gtk devel libs installed and they are located in my /usr/lib/pkgconfig directory. I have searched on this board about this issue and i have done some of thethings that the people have suggested. one of them trying to set the PKG_CONFIG_PATH to the proper directory to have it find the right libs. but that does not seem to help. Does anyone know of another way about doing this? any suggestions are appreciated.
