[gentoo-user] Building lapack failed

Hi! 

I try to install lapack on my machine. 

This is what I get when I try to emerge lapack:
...
Source unpacked.
>>> Compiling source in /var/tmp/portage/lapack-3.0/work/LAPACK ...
g77 -O2 -march=i686 -fomit-frame-pointer  -c -o cbdsqr.o cbdsqr.f
gfortran: no input files
make: *** [cbdsqr.o] Error 1

!!! ERROR: sci-libs/lapack-3.0 failed.
Call stack:
  ebuild.sh, line 1546:   Called dyn_compile
  ebuild.sh, line 937:   Called src_compile
  lapack-3.0.ebuild, line 22:   Called die

!!! make failed
!!! If you need support, post the topmost build error, and the call stack if relevant.

I had problems with blas before, because I could not find g77 on my system but I fixed this by writing a shell script called g77 that points to "/usr/lib/R/bin/f77". So blas did compile but now lapack fails. 

What can I do about this?

Regards
JC

I think bug #146448 [1] is the most relevant bug (which you should be able to 
find on your own). Unfortunately it provides no solutions. This package 
simply isn't prepared for gcc-4.x yet.

Apologize my ignorance... Why do you need this package anyway? No package 
currently in the tree depend on sci-libs/lapack...

....

Hmm.... actually this seems to work for me:

# echo -e '#!/bin/sh\ngfortran -ff2c' > /usr/bin/g77 && chmod +x /usr/bin/g77
# emerge -va sci-libs/lapack
# rm /usr/bin/g77

I strongly suggest that you remove it when you're done since this isn't the 
supported solution. At the very least mention it if you ever file a bug where 
it might have an impact...

As you can read on the bug those packages are deprecated. Still I've made a 
couple of patches (attached on the bug) that makes it compile with 
gfortran... (The eclasses really do all the work...)

Thank you!

I need the lapack stuff becaus I am going to try some FEM tools like elmer, salome and netgen. ;) (This is the reason for the trouble)

And thanks for the hint to remove the hack !!!
