scalapack incompatible with blacs

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20060130 Red Hat/1.7.12-1.4.2 Description of problem: scalapack-1.7-7.fc4 from Fedora Extras is incompatible with blacs-1.1-18.fc4 from Fedora Extras. Specifically, scalapack has undefined symbols with trailing double underscores such as blacs_pinfo__ but blacs defines them as blacs_pinfo_ and so on. Given that blacs is a dependancy for scalapack, this is silly. I guess the maintainer of blacs released a new version and didn't check whether it broke scalapack. (Also silly is the strange splitting of the blacs package contents into blacs and blacs-devel which occurred in the 1.1-18.fc4 release, with libmpiblacs.a and the symlink /usr/lib/libmpiblacs.so in the -devel package.) Version-Release number of selected component (if applicable): scalapack-1.7-7.fc4 How reproducible: Always Steps to Reproduce: 1. Compile code that requires scalapack 2. Link 3. Actual Results: Missing symbols all over the place Expected Results: Linking between scalapack and blacs should work, especially given that the former requires the latter. Additional info: Also, the SRPM does not rebuild on FC4: specifically, (1) the CDEFS in SLmake.inc needs to be changed from -Df77IsF2C to -DAdd_ because gfortran only adds one underscore, unlike g77 which adds two underscores. (2) there is a dependancy on libutil (references openpty), so that needed adding to EXTRALIBS in SLmake.inc (3) the BuildRequires of blas-devel, blacs-devel and glibc-devel should be added to the spec file, and probably so should Requires of blas-devel and blacs-devel now that the .a's and the .so's have been put into those packages. I've fixed these issues myself, and will upload the new spec and patches in a minute or two.
Created attachment 124504 [details] The changes to SLmake.inc Should be applied to SLmake.inc as distributed, i.e. is not a patch to the patches in the SRPM
Created attachment 124505 [details] Re-generated 64bit patch for correctness As with 124504, this replaces the patch of the same name from 1.7-7.fc4
Created attachment 124507 [details] New SPEC file New BuildRequires and Requires, bump version number
New RPMs and SRPM are available at http://www.cmmp.ucl.ac.uk/~atg/scalapack/ but untested yet due to a gfortran bug
scalapack is built for FC-3, FC-4, and FC-5 now. Thanks for the patches.
