Building RPMs is simple, but a few gotcha's prevent us from using the standard infrastructure. Follow the recipe below, but beware that it may require a few updates...

First, get the sources from the last successful build, and install it:

      yumdownloader --source --destdir /tmp CERNLIB && rpm -ivh /tmp/CERNLIB-2006*.src.rpm

In the specfile ~/rpmbuild/SPECS/CERNLIB-binaryonly.spec you see that the %prep section prepares the source files from the AFS area /afs/cern.ch/sw/lcg/external/cernlib/.... This of course only works on machines that have AFS access, ie. it does not work from Koji...

Also, the Cernlib builds for x86_64 have never been properly tested, so we tend to only provide {i386,i686} RPMs. However, the x86_64 sources are still tarred up, as to allow for future improvements. This implies that we need both 32bit and 64bit source files in AFS before we can build.

To build the RPM, simply run

    rpmbuild --ba ~/rpmbuild/SPECS/CERNLIB-binaryonly.spec --target i686
