Thanks for the bug report. Could you please provide a sample file and the command line used to compile it where it fails with the above error?
I am not very familiar with fortran, but my guess is this has to do with the linking changes in 11.10+. I just compiled: http://www.physics.orst.edu/~rubin/nacphy/lapack/codes/eigen-f.html on 12.04 using the command line: gfortran test.f90 -llapack; and it compiles without errors. However using: gfortran -llapack test.f90; will fail with the error above, because of the linker changes (but will succeed on 10.04). If this is the problem, see http://wiki.debian.org/ToolChain/DSOLinking for a quick overview of the changes. ** Changed in: lapack (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1030952 Title: zgeevx undefined To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lapack/+bug/1030952/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
