[petsc-users] --download-fblaslapack libraries cannot be used

[Fande Kong]

OK. I finally got PETSc complied.

"-lgfortran" was required by fblaslapack
"-lmpifort" was required by mumps.

However, I had to manually add the same thing for hypre as well:

git diff
diff --git a/config/BuildSystem/config/packages/hypre.py
b/config/BuildSystem/config/packages/hypre.py
index 4d915c312f..f4300230a6 100644
--- a/config/BuildSystem/config/packages/hypre.py
+++ b/config/BuildSystem/config/packages/hypre.py
@@ -66,6 +66,7 @@ class Configure(config.package.GNUPackage):
     args.append('--with-lapack-lib=" "')
     args.append('--with-blas=no')
     args.append('--with-lapack=no')
+    args.append('LIBS="-lmpifort -lgfortran"')
     if self.openmp.found:
       args.append('--with-openmp')
       self.usesopenmp = 'yes'


Why hypre could not pick up LIBS options automatically?


Thanks,

Fande,
