I am trying to compile the CVS ghemical package and while configure completed successfully, it didn't seem to check for all the required libraries. I got the following error during make: Package gtkglext-1.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `gtkglext-1.0.pc' to the PKG_CONFIG_PATH environment variable No package 'gtkglext-1.0' found It is not a problem as i found i don't have gtkglext installed but it seems like this should be detected by the configure script. So i added this line: PKG_CHECK_MODULES(GTKGLEXT, gtkglext-1.0 >= 1.0.5) -Ephraim (Donald)
