Bug 470908 – app-eselect/eselect-cblas-0.1 creates broken symlink /usr/lib64/libcblas.a

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Coacher 2013-05-21 19:17:39 UTC]

I have app-admin/eselect-cblas-0.1 and sci-libs/gsl-1.15 installed.
After installation (or if I do it manually) gsl is selected as CBLAS implementation via eselect. It creates broken symlink:

ls -la /usr/lib64/libcblas.a
lrwxrwxrwx 1 root root 13 May 21 23:10 /usr/lib64/libcblas.a -> libgslcblas.a

Please fix.

I am experiencing the same issue with eselect-cblas, eselect-blas and eselect-lapack.

Note that eselect returns a nonzero exit code when trying to set the blas/cblas/lapack implementation, so it seems like it is itself aware that something went wrong...

    app-eselect/eselect-{blas,lapack}: new design for BLAS/LAPACK switch.
    
      As discussed in the gentoo-dev, it is decided to adopt the runtime
      switching of BLAS/CBLAS that has been proved by the experience of
      Debian.  The Gentoo libgcc-style ld.so.conf runtime switching has
      been adopted as well, so as to avoid changing symlinks in /usr
      ignoring package manager.
    
      This design solves all the remaining problems regarding BLAS/LAPACK,
      thus making alternative-2.eclass (runtime switching of build
      options) and proposed USE_EXPAND (PYTHON_TARGET like eclass)
      obsolete.
    
      Finally we are at it.  Thanks to all for years of ideas, debates and
      hard work.
