Bug 699816 – [PATCH] sci-libs/arpack-3.1.5 fails to find liblapack of sci-libs/lapack-reference-3.2.1-r4

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description John Doe 2019-11-11 12:30:59 UTC]

arpack fails to build because it can't find the lapack library using pkg-config (see attached log).

1. app-eselect/eselect-lapack is unable to select sci-libs/lapack-reference-3.2.1-r4, because it checks for liblapack.so.3 which the package does not install.

2. app-eselect/eselect-lapack does not write the PKG_CONFIG_PATH to /etc/env.d, so pkg-config is unable to find lapack.

The attached patch for eselect-lapack fixes the above issues and allows to select sci-libs/lapack-reference by running:
eselect lapack add lib64 /usr/lib64/lapack/reference lapack-reference
eselect lapack set lapack-reference

This fixes building arpack.

One thing I am not sure about is if the 50 in the filename /etc/env.d/50lapack is allowed or if there is a specific ordering convention which calls for a different number.

Another thought: If there is only one lapack version installed, it should probably add and select itself with eselect-lapack.

Reproducible: Always

Dear John Doe,

Thank you so much for patch.  I apologize for the confusion.  We have deprecated the lapack-reference packages and moved to sci-libs/lapack-3.8.0.  Let's move to bug 698756 for further discussions.

Benda
