[petsc-users] Error while building PETSc with MATLAB

Fri Sep 1 12:23:51 CDT 2023

yes [and remove fblaslapack. don't know if hypre will work here].

i.e:

./configure --with-mpi-dir=/home/vit/sfw/linux/openmpi/4.1.4 COPTFLAGS=-O3 CXXOPTFLAGS=-O3 FOPTFLAGS=-O3 PETSC_ARCH=linux-opt --with-debugging=0 --with-x=0 \
--with-matlab-dir=/usr/local/MATLAB/R2020b --with-matlab-engine=1 -with-blaslapack-dir=/usr/local/MATLAB/R2020b --known-64-bit-blas-indices=1
