Bug 596036 – sci-libs/lapack-reference-3.6.0 ebuild removes pkgconfig under install stage on non-amd64

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Dmitry Derevyanko 2016-10-03 13:23:50 UTC]

Line in ebuild:
rm -rf "${ED}"/usr/lib/ || die
removes pkgconfig file and libs.
Without it lapack-reference ebuild installs all needed files.

[Comment 1 Matthias Maier 2016-10-09 03:32:00 UTC]

The rm -rf you quote simply cleans up after the ebuild moved all relevant installation files to /usr/lib64/lapack/reference.

Have you selected the appropriate lapack provider via eselect?


lapack-reference installs the following files:

# qlist lapack-reference
[...]
/usr/lib64/lapack/reference/liblapack.so.3.6.0
/usr/lib64/lapack/reference/lapack.pc
/usr/lib64/lapack/reference/liblapack.so.3
/usr/lib64/lapack/reference/liblapack.so


if lapack-reference is chosen as lapack provider the following symlinks are created:

in /usr/lib64 (for amd64):
liblapack.a -> lapack/reference/liblapack.a
liblapack.so -> lapack/reference/liblapack.so
liblapack.so.3 -> lapack/reference/liblapack.so.3

in /usr/lib64/pkgconfig (for amd64):
lapack.pc -> ../lapack/reference/lapack.pc

This will remove all files for x86.

With line after emerge -1 lapack-reference I get this:
~ $ qlist lapack-reference
/etc/env.d/lapack/lib/reference         
/usr/share/doc/lapack-reference-3.6.0/README.bz2

Thanks for the pointer. I was blind, will fix.

    sci-libs/lapack-reference: do not remove /usr/lib, bug #596036
    
    Non non-amd64 systems "$(get_libdir)" might actually be "lib". So do not
    blindly delete this folder.
