If you're missing something at least do an attempt to finding a srpm of the package you need. Google for "fftw srpm". I came up with http://dries.ulyssis.org/rpm/packages/fftw3/info.html I'd try grabbing the http://ftp.belnet.be/packages/dries.ulyssis.org/fedora/fc6/i386/SRPMS.dries/fftw3-3.1.1-1.fc6.rf.src.rpm package install it and build your one rpm like so: # wget http://ftp.belnet.be/packages/dries.ulyssis.org/fedora/fc6/i386/SRPMS.dries/fftw3-3.1.1-1.fc6.rf.src.rpm # rpm -Uvh fftw3-3.1.1-1.fc6.rf.src.rpm # cd /usr/src/redhat/SPECS # rpmbuild -bb fftw3 # cd ../RPMS (if the build goes correcting (writing rpm....)) # rpm -Uvh ffw3* --test (hopefully this thing build the -devel rpm simultaneously too). FC6 source rpms should be very close to FC7 standards so there should be to many other dependancies to settle. Yum can take care of most of those though.... -eric wood
