[GRASS-user] Building 8.2.1: not finding OpenBLASS

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

Rich,

I cannot find any support for OpenBLAS in configure. Maybe, you can try symlinking libopenblas.so to libblas.so. I use Slackware64-15 too, but I just use BLAS.

Thanks,

Markus,

My apologies. I've not had a project needing grass over the past few years
so I forgot about it.

The file's attached. It shows the usual errors and warnings I've seen when I
was grabbing the development builds (can't find those now), and BLAS begins
on line 3347. I don't see why configure can't find lblas, but I don't know
the code.

Thanks,

Rich

Huidae,

I thought that the line, `--with-blas` included OpenBLAS.

I chose OpenBLAS because the SBo SlackBuild page for grass (for a long
out-of-date 7.8.0; the maintainer hasn't responded to my request for an
update) says that OpenBLAS is optimized and includes LAPACK.

Rich,

Checking the OpenBLAS package from http://www.slackware.com/~alien/slackbuilds/OpenBLAS/pkg64/15.0/, I think your OpenBLAS installation is somehow broken. doinst.sh should create symlinks for you automatically on installation, but you don’t have them in /usr/lib64 based on your grep. Maybe, you can try reinstalling it and see if you get /usr/lib64/libblas.so then. GRASS’s configure only checks for libblas.so, so it won’t be able to pick up libopenblas.so as is. The easiest fix would be just download the package and install it using installpkg. http://www.slackware.com/~alien/slackbuilds/OpenBLAS/pkg64/15.0/OpenBLAS-0.3.12-x86_64-1alien.txz

Yeah, unfortunately, SlackBuild for GRASS is still 7.8.0. Maybe, it’s no longer maintained if the maintainer hasn’t responded.

Thanks,
Huidae

Hĭdae,

Okay. I'll remove the existing SBo OpenBLAS and replace it with ALIEN Bob's
package.

Results to follow.

Thanks,

Huidae,

That fixed the problem. The source configured, built, and installed as it
had always done in the past.

For the past many years I had a copy of the git repo and would pull changes
when I prepared to run grass and rebuilt and reinstalled from a clean source
tree.

I looked at the Download page on the web site but didn't see the dev source
github repo URL in the source code portion. Does one still exist? If so,
I'll make a new clone of it and continue working with the current source and
reporting issues in the infrequent times they bite me.

Thanks again,

Rich

Rich,

If you have used the Git repo before, the URL should be the same: https://github.com/OSGeo/grass

Thanks,
