Yes, it exists, but no it is a symlink to the wrong pc file: |
| 55 |
|
| 56 |
$ ls -ahl /usr/lib64/pkgconfig/lapack.pc |
| 57 |
lrwxrwxrwx 1 root root 77 Oct 26 15:19 /usr/lib64/pkgconfig/lapack.pc -> ../../../etc/env.d/alternatives/lapack/_current/usr/lib64/pkgconfig/lapack.pc |
| 58 |
|
| 59 |
Which package is to provide this symlink? It seems that it is a stale |
| 60 |
symlink from before -llapack was renamed to -lreflapack recently? |
| 61 |
|
| 62 |
I'm experimenting with the different implementations, it is entirely |
| 63 |
possible that I'm in some undefined state. Now, how to fix it? |
| 64 |
|
| 65 |
Thanks! |
