Red Hat Bugzilla – Bug 442915
missing dependencies for blas-devel and lapack-devel
Last modified: 2008-07-10 11:41:17 EDT
Description of problem: Invariably users of blas/lapack have either of the above devel packages installed - but they dont' work at compile time - because of missing dependencies: Version-Release number of selected component (if applicable): blas-devel-3.1.1-2.fc8 lapack-devel-3.1.1-2.fc8 gcc-gfortran-4.1.2-33 Additional info: Please add the following dependencies. - lapack-devel depends on blas-devel The reason for the above is obvious. lapack is generally used as: gfortran -llapack -lblas - blas-devel depends on gcc-gfortran [or more apprioriately libgfortran.so,.a] This one is not that obvious - but its the correct dependency. Normally folks use blas/lapack from fortran only - so gfortran is always there. But one can use blas/lapack from C aswell - and many software packages do this. In this case - one has to do: 'gcc -llapack -lblas -lgfortran' Ideally you would have a separate package libgfortran-devel which has libgfortran.a, libgfortran.so. In the absence of this package - the correct dependency is on gcc-gfortran Note: This problem probably exists on RHEL versions aswell [I know RHEL5 has this problem]. It would be good if it can be fixed aswell.

Thanks for fixing this dependency problem. Its appears to work as expected on Fedora9. [I have both x86_64 & i386 libs installed - and both show proper dependencies]
Actually I spoke a bit too soon. This is misbehaving in multilib case.. On attempting to install lapack-devel.i386 - yum prompts to install blas-devel.x86_64 - instead of blas-devel.i386 I guess gcc-gfortran.x86_64 is fine - as it provides both 32bit and 64bit libgfortran.a/so files ****************************************************************************** [root@asterix ~]# yum install lapack-devel.i386 Loaded plugins: changelog, refresh-packagekit local | 951 B 00:00 Setting up Install Process Parsing package install arguments Resolving Dependencies --> Running transaction check ---> Package lapack-devel.i386 0:3.1.1-4.fc9 set to be updated --> Processing Dependency: blas-devel = 3.1.1-4.fc9 for package: lapack-devel --> Running transaction check ---> Package blas-devel.x86_64 0:3.1.1-4.fc9 set to be updated --> Processing Dependency: gcc-gfortran for package: blas-devel --> Running transaction check ---> Package gcc-gfortran.x86_64 0:4.3.0-8 set to be updated --> Finished Dependency Resolution Dependencies Resolved ============================================================================= Package Arch Version Repository Size ============================================================================= Installing: lapack-devel i386 3.1.1-4.fc9 updates 4.1 M Installing for dependencies: blas-devel x86_64 3.1.1-4.fc9 updates 182 k gcc-gfortran x86_64 4.3.0-8 fedora 4.2 M Transaction Summary ============================================================================= Install 3 Package(s) Update 0 Package(s) Remove 0 Package(s) Total download size: 8.5 M Is this ok [y/N]:
I'm not sure I can reasonably resolve this. With the new rpm, I can specify that Requires: foo-devel(x86-32) is what I want, but I can't do this for any existing releases (F-8, F-9).

Ok. I guess this new rpm is currently in rawhide and will be in F-10/RHEL6. So this fix to blas/lapack will be in upcoming releases. This is fine by me. Hopefully libgfortran-devel split takes place before that [as per #442919] and blas-devel/lapack-devel packages are updated with this change aswell.
