cant find BLAS during cmake Trilinos

[SunnyQbang]

Hi,
I encountered an issue while installing Trilinos. It cannot find the BLAS library, even though I have already installed BLAS on my server and set the path. This is the partial CMake log

Or, just set:
-DTPL_BLAS_LIBRARIES=';;...'
to point to the full paths for the libraries which will
bypass any search for libraries and these libraries will be used without
question in the build. (But this will result in a build-time error
if not all of the necessary symbols are found.)

which is pointed to in the file:
/public/home/jshhuang03/bin/dealii/tmp/unpack/Trilinos-trilinos-release-14-4-0/TPLsList.cmake

TIP: One way to get past the configure failure for the
TPL 'BLAS' is to simply disable it with:
-DTPL_ENABLE_BLAS=OFF
which will disable it and will recursively disable all of the
downstream packages that have required dependencies on it, including
the package 'MueLu' which triggered its enable.
When you reconfigure, just grep the cmake stdout for 'BLAS'
and then follow the disables that occur as a result to see what impact
this TPL disable has on the configuration of Trilinos.

And this partial trilinos.package

BLAS_DIR="/public/home/jshhuang03/lib"
LAPACK_DIR="/public/software/mathlib/libs-gcc/lapack/3.9.1"

if [ ! -z "${BLAS_DIR}" ]; then
cecho ${INFO} "trilinos: configuration with BLAS_DIR=${BLAS_DIR}"
CONFOPTS="${CONFOPTS}
-D BLAS_LIBRARY_DIRS:STRING=${BLAS_DIR}"

cecho ${INFO} "trilinos: configuration with LAPACK_DIR=${LAPACK_DIR}"

this two raws which i add is the path where BLAS install in my cluster
BLAS_DIR="/public/home/jshhuang03/lib"
LAPACK_DIR="/public/software/mathlib/libs-gcc/lapack/3.9.1"

but it cant find BLAS .....

Any help would be very much appreciated.Thank you!!

Cheers

@SunnyQbang Have you checked whether the libraries blas and/or blas_win32are present in /public/home/jshhuang03/lib?

[SunnyQbang]

yep i module load apps/BLAS/3.10.0, and in its path ,i find the

and i also complie a new BLAS

but it doesnt work yet

i also use ln -s librefblas.a blas and ln -s librefblas.a blas.a
but it doesnt work

Please post the cmake configure line you're using. I suspect a mistake there. Also see https://docs.trilinos.org/files/TrilinosBuildReference.html#specifying-the-location-of-the-parts-of-an-enabled-external-package-tpl for an example of specifying blas/lapack locations.

[cgcgcg]

Neither blas_LINUX nor librefblas are recognized library names. You should be able to convince cmake to use them by passing

-D BLAS_LIBRARY_NAMES="blas_LINUX"

or

-D BLAS_LIBRARY_NAMES="refblas"

Thank you sir!I am new with C/C++,so i cant tell what u meaning...
cmake configure line?
i just run a candi.sh, i dont use cmake configure
show what for u
can u please tell me more simplely?

Looking at this file
https://github.com/dealii/candi/blob/33f3c4be63bf8e755ffc6036cce07aa9a045a63d/deal.II-toolchain/packages/trilinos.package
you might want to try to also set BLAS_LIB="refblas".

[SunnyQbang]

thank you! i follow u suggestion #13802 (comment)
so i modify the trilinos.packages

I add the -D BLAS_LIBRARY_NAMES="blas_LINUX"
but i doesnt work,
am i misunderstand your meaning?
Thank you for your reply sir! @cgcgcg

[SunnyQbang]

Looking at this file https://github.com/dealii/candi/blob/33f3c4be63bf8e755ffc6036cce07aa9a045a63d/deal.II-toolchain/packages/trilinos.package you might want to try to also set BLAS_LIB="refblas".

so i should add a new row BLAS_LIB="refblas" or BLAS_LIB="blas_LINUX"? @cgcgcg

[cgcgcg]

I don't know what they are. "refblas" could suggest that it's a reference implementation. So that could be slow. But they might also just be symlinked to each other.

[SunnyQbang]

but i still very confused why i have already finished compiling the BLAS and i have librefblas.a ,but the cmake cant find it... @cgcgcg

[cgcgcg]

Did you use candi to compile blas? The names of those libraries look somewhat non-standard.

EDIT: Just checked, candi uses openblas. So you must have installed something else.

EDIT2: Reread the thread. Go with the system package, even if the name is weird.

[SunnyQbang]

no sir, i just trynna use candi.sh to insatall aspect,the trilinos is the must,this is a specific link https://community.geodynamics.org/t/installation-without-internet-access-using-candi/3928
@cgcgcg

[cgcgcg]

Can you share the output of the script?

[SunnyQbang]

you mean the candi.sh output? @cgcgcg

[cgcgcg]

What I would like to see is the error message with -D BLAS_LIBRARY_NAMES="blas_LINUX".

[SunnyQbang]

line132:-D BLAS_LIBRARY_NAMES="blas_LINUX"

@cgcgcg

is correct to add -D BLAS_LIBRARY_NAMES="blas_LINUX" to trilinos.package or not? thank u sir

[cgcgcg]

Sorry, but no.

CONFOPTS="${CONFOPTS} \
      -D BLAS_LIBRARY_DIRS:STRING=${BLAS_DIR} \
      -D BLAS_LIBRARY_NAMES=blas_LINUX"

[SunnyQbang]

sorry ..my bad

still cant find blas_LINUX sir @cgcgcg

and this FindTPLBLAS.cmake

[cgcgcg]

Ok. Let's try this:

CONFOPTS="${CONFOPTS} \
      -D BLAS_LIBRARIES=/public/software/apps/BLAS/3.10.0/lib/libblas_LINUX.a"
