octave-devel @3.3.52 +gcc44: mkoctfile doesn't find BLAS and LAPACK

[lukas.reichlin@…]

Hello,

There is a problem with mkoctfile in octave-devel 3.3.52 when Fortran code requires BLAS and LAPACK: If I don't add the options "-Wl,-framework" "-Wl,vecLib" to each call of mkoctfile in Makefile [2], the control package [1] fails to build. However, adding these options would break package installation on non-macintosh platforms. This is not an option. Therefore, it looks like a modified Portfile or a patch to octave-devel is needed which includes "-Wl,-framework" "-Wl,vecLib" by default.

BTW:

• There are no problems building "control" when using MacPorts octave-3.2.4, neither PPC nor Intel.
  
• Note that is possible to compile individual oct-files by src/makefile_*.m and they include the "-Wl,-framework" "-Wl,vecLib" option
  
• The only thing that works for me without "-Wl,-framework" "-Wl,vecLib" with octave 3.3.52 is src/makefile_helpers.m, probably because those functions are pure C++.
  
• inst/test_control.m executes all tests at once.

Please let me know if you have any questions or comments.
Best Regards,
Lukas

Package Download Link: ​http://octave.svn.sourceforge.net/viewvc/octave/trunk/octave-forge/main/control/?view=tar

You can get my package from [1] by clicking the "Download GNU tarball" link. Rename the file from octave-control.tar.gz to control.tar.gz and install it inside octave by
cd <location of the package>
pkg install control*
If installation succeeds, try "pkg list" and "test_control". Please be patient, the installation may take several minutes. There's no output during a (successful) installation, just wait until the next octave:#> prompt shows up.

Sorry for the bad formatting!

Cc Me!

[michaelld (Michael Dickens)]

As of r78773, octave-devel is at version 3.4.0; does this issue still apply?

[michaelld (Michael Dickens)]

Lukas - Is this ticket still an issue with Octave 3.4.3?

[lukas.reichlin@…]

No, it isn't.

[michaelld (Michael Dickens)]

Great; then I'll close out this ticket.
