[GRASS-user] Building 8.2.1: not finding OpenBLASS

[Rich Shepard]

I'm trying to build 8.2.1 on Slackware64-15.0. My configuration file is:
./configure \
--enable-64bit \
--with-libs=/usr/lib64 \
--with-postgres \
--with-postgres-includes=/usr/include/postgresql/server/ \
--with-postgres-libs=/usr/lib64/postgresql/14/lib/ \
--with-sqlite \
--with-sqlite-includes=/usr/include/ \
--with-sqlite-libs=/usr/lib/ \
--with-cairo \
--with-blas \
--with-lapack \
--with-freetype \
--with-freetype-includes=/usr/include/freetype2 \
--with-cxx \
--with-geos \
--with-gdal \
--with-nls \
--with-python3 \
--with-pthread \
--with-proj-share=/usr/share/proj \
--with-wxwidgets \
--enable-largefile \
--with-openmp \
--with-x \
--with-pdal=/usr/bin/pdal \
--with-libLAS

After checking for needed components the script stops telling me it cannot
locate a BLAS library.

Here:
# ls /usr/lib64 | grep blas
libgslcblas.so@
libgslcblas.so.0@
libgslcblas.so.0.0.0*
liblas.so@
liblas.so.2.4.0*
liblas.so.3@
liblas_c.so@
liblas_c.so.2.4.0*
liblas_c.so.3@
liblaszip.so@
liblaszip.so.6@
liblaszip.so.6.0.0*
libopenblas.so@
libopenblas.so.0@
libopenblasp-r0.3.12.so*

What have I done incorrectly?

TIA,

Rich
