First of, supposing you are on amd64, does |
| 48 |
/usr/lib64/pkgconfig/lapack.pc |
| 49 |
exist? It should be a link pointing to |
| 50 |
../../../etc/env.d/alternatives/lapack/_current/usr/lib64/pkgconfig/lapack.pc |
| 51 |
itself a link to /usr/lib64/pkgconfig/reflapack.pc |
| 52 |
It is possible that some of these links have not been created properly. |
| 53 |
There used to be bug about it on prefix (I don't know if anyone improved |
| 54 |
my prefix bandaid). There is also the possibility that remnant from the |
| 55 |
non-sci overlay mechanism interfere. |
