Description michel zou 2023-11-10 15:50:31 CET

it would seem that lapacke static lib is not compiled with fPIC:

Michel, sorry to have left you; and thank you for the report.
How did you encounter this?
Please say what problem results from your diagnosis.

Your complaint comes I suppose from the end of comment 0:
[   32s] /usr/bin/ld: /usr/lib64/liblapacke.a(lapacke_sgeqrf.c.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
[   32s] /usr/bin/ld: failed to set dynamic section sizes: bad value
[   32s] collect2: error: ld returned 1 exit status

From the Suse build log:
[   33s] /usr/bin/c++ -fPIC -I/usr/include/lapacke ...

It is a complicated subject, and I got the impression that compiling with PIC (Position Independant Code) is normal, even though in some situations not strictly necessary.
It could be an isolated case where the compile flag -fPIC is missing, but begs the question of whether there are others.

No one packager deals with this, so assigning it globally. CC'ing Joseph who last committed it.

Comment 3 michel zou 2023-11-17 08:35:33 CET

Hello, the -fPIC flag is present in the log I'm showing because I'm try to build a shared lib that links to lapacke static lib.

Now if -fPIC its not used when linking lapack itself (in mageai's lib64lapack-static-devel package) then we get the error "relocation R_X86_64_32 ... can not be used when making a shared object"
