Sorry to interrupt the thread, but if the Ubuntu build logs are anything to go by, I guess we could face lapack FTBFSing on us on several architectures (notably, even i386). https://launchpad.net/ubuntu/+source/lapack/3.0.20000531a-1.1ubuntu1 Though I cannot say anything about the cause (I have to test it out myself), one thing I am unhappy about is that the current Blas in Debian is one I re-packaged based on the latest upstream sources, part of which is based on Lapack sources (see http://lists.debian.org/debian-toolchain/2007/12/msg00012.html for details), and Camm's Debian packaging. Now, building the "old" Lapack against the new source code based Blas doesn't sound right to me. Matthias agreed with this, but said he was unable to switch to the new Lapack since he, like me, did not know how to handle Camm's heavy patches. My cursory glance (last month) to this problem led me to believe that several of Camm's patches have been merged upstream in Lapack, while others (which do not apply per se) may or may not be required. Therefore, my first attempt (unless Camm comes back to take over by then) would be to rebuild the Lapack upstream sources without Camm's patches. The rationale behind this is the fact that the last upload of a gfortranized lapack3 to experimental (which Matthias did based on a package I made some time back) built on all architectures where the old refblas3 built, and on other arches, it didn't build due to Blas absence: http://experimental.ftbfs.de/new/package.php?p=lapack3&suite=experimental I would, therefore, try out two things; one would be a totally unpatched Lapack, and the second level would be to painstakingly merge Camm's patches with the new Lapack. However, the latter, I assure you, will be _really_ painful; I had to spend several hours for Blas, and if that is any indication, re-patching Lapack is going to be worse (though I am willing to do it, should the need to do it arise). But, as always it'd be great if someone else could do this before me! :-) (Please note that I am no expert in either the toolchain or Fortran, but I just hope my remarks make sense. Apologies for any mistakes I make). Thanks.
