Description Martin Jambor 2024-06-02 09:35:40 UTC

GCC 14 newly by default treats as errors a number of situations which
before were only warnings.  For more information see
https://gcc.gnu.org/gcc-14/porting_to.html and meta bug #1220571.

Because of this, package lapack fails to compile.  This can be seen online
at:
https://build.opensuse.org/package/live_build_log/openSUSE:Factory:Staging:Gcc7/lapack/standard/x86_64

It can be reproduced locally with command: osc build --clean
--alternative-project home:rguenther:nextgcc


The error (that halts the build) is:

[  185s] In file included from ../include/lapack.h:11,
[  185s]                  from ../include/lapacke.h:37,
