3.12.1 fails to build

With GCC 14.2

should read $ WORK (*) in all four ?gelqs.f files under SRC/DEPRECATED presumably

[wdconinc]

FYI, #1094

[thierry-FreeBSD]

The same kind of error is displayed when building xlapack (on FreeBSD with gfortran 13):

[martin-frbg]

As far as I can tell, "xlapack" appears to be a FreeBSD-specific creation that is simply stock Reference-LAPACK built against the extended-precision XBLAS instead of its included Reference-BLAS (?)

[thierry-FreeBSD]

It sets USE_XBLAS to ON, and depends on xblas. Since USE_XBLAS is part of Lapack's CMakeLists.txt, I didn't know that is was specific to FreeBSD!

[martin-frbg]

At least FreeBSD appears to be the only ones packaging it, if google is still to be trusted (somewhat). Anyway as far as I can tell it is basically a build variant of Reference-LAPACK so whoever distributes it must update their sources to include the post-3.12.1 patches

[thierry-FreeBSD]

I do not know if it still used... maybe I'll mark it deprecated to see if I get some feedback.
Anyway, does lapack (with the latest patches) build for you when USE_XBLAS is set, with xblas 1.0.248?
