First of all, greetings to all of you. :) To the problem. In the directory, gtk+-2.2.4 I did the following: PKG_CONFIG=/usr/local/bin /* pkg-config executable is here for sure */ export PKG_CONFIG PKG_CONFIG_PATH=/usr/lib /* Not very sure whether the libraries are here! */ export PKG_CONFIG_PATH ./configure --prefix=/usr/local Installing pkg-config 0.15.0 before configuring GTK went fine: ./configure --prefix=/usr/local make make install However, when configuring GTK+2.2.4 I get the following error message: *** Your version of pkg-config is too old. You need version 0.9.0 or newer. *** See http://www.freedesktop.org/software/pkgconfig configure: error: Library requirements (glib-2.0 >= 2.1.4 atk >= 1.0.1 pango >= 1.0.1) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them. Question A) Why does it complain about pkg-config being too old? I set the environment variable PKG_CONFIG to /usr/local/bin where pkg-config is located. Doing: jack@linux:/usr/local/bin> pkg-config --version 0.15.0 ... confirms my version number (strangely, I cannot call pkg-config from other directories). Question B) The configure error message prompts me to set the PKG_CONFIG_PATH env var which I've done as shown earlier on. I must admit I'm not very sure whether the libraries are there though. How can I know for sure? Perhaps one can give me a pkg-config library file which I can search for? Thanks in advance. :) _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
