From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050308 Firefox/1.0.1 Fedora/1.0.1-5 Description of problem: /usr/lib/pkgconfig/gnopernicus-1.0.pc requires "cspi-1.0", but the package which provides it (at-spi-devel) is not in gnopernicus' list of package dependencies. This results in a broken pkgconfig dependency chain, which is not limited to querying gnopernicus-1.0.pc. For instance, it breaks "pkg-config --list-all" as parsed by some applications and makes the query print an error message and return an error code (!), too. Also broken: $ pkg-config --exists gnopernicus-1.0 || echo "no" no $ pkg-config --cflags gnopernicus-1.0 Package cspi-1.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `cspi-1.0.pc' to the PKG_CONFIG_PATH environment variable Package 'cspi-1.0', required by 'gnopernicus', not found Whenever a package contains a pkgconfig template, it ought to have a complete set of dependencies which provide every dependency listed in the pkgconfig file's "Requires:" line. Package gnopernicus could require at-spi-devel easily if a -devel package were split off. It contains headers and build-time library softlinks, but doesn't "Provides: gnopernicus-devel = %version-%release", btw. Version-Release number of selected component (if applicable): gnopernicus-0.10.4-1 How reproducible: Always Steps to Reproduce: - Additional info:
