compiling sci-mathematics/octave failed with got this error

Code:

configure: error: A BLAS library was detected but found incompatible with your Fortran 77 compiler settings


I am using
hppa64-unknown-linux-gnu-7.3.0 *
compiled with --enable-languages=c,c++,fortran
(default gentoo setup)

Code:
ldd /usr/lib/blas/reference/libblas.so.0.0.0


Code:
libgfortran.so.4 => /usr/lib/gcc/hppa2.0-unknown-linux-gnu/7.3.0/libgfortran.so.4 (0xf8192000)         
libm.so.6 => /lib/libm.so.6 (0xf7efa000)         
libgcc_s.so.4 => /usr/lib/gcc/hppa2.0-unknown-linux-gnu/7.3.0/libgcc_s.so.4 (0xf7dd8000)         
libc.so.6 => /lib/libc.so.6 (0xf7afa000)

Greetings,

I have the same issue on the x86-64 architecture

Quote:
checking for sgemm_ in -lscs... (cached) no
checking for sgemm_ in -lcomplib.sgimath... (cached) no
checking for sgemm_ in -lblas... (cached) no
checking for sgemm_ in -lblas... (cached) no
configure: error: A BLAS library was detected but found incompatible with your Fortran 77 compiler settings.

!!! Please attach the following file when seeking support:
!!! /var/tmp/portage/sci-mathematics/octave-4.2.2/work/octave-4.2.2/config.log
* ERROR: sci-mathematics/octave-4.2.2::gentoo failed (configure phase):
* econf failed
*
* Call stack:
* ebuild.sh, line 124: Called src_configure


In my case, this would seem to belong on the "Portage and Programming" section of the forum, as I am not on an alternative architecture.

My impression is that this looks manageable to solve with some toolchain investigation and reconfiguration, but it would be nice to find information from someone who's solved it already.

You need to re-emerge BLAS (and LAPACK while you are at that)

This did the trick for me! Thank you! :D

The relevant details were 2 lines at the bottom of the bug report
