Spack installation failure about strumpack HOT 7 CLOSED

The error seems unrelated to STRUMPACK.
Are you able to install other packages using spack?

from strumpack.

Hi @pghysels.

As a test, I have successfully installed other packages using spack.

Hints suggested that g++ may not support some syntax.

The error message suggests that the system header files which are being included use non-standard features (blocks: ^ symbol), which gcc doesn't support, but clang does.
Probably your best option at the moment is to use clang instead of gcc.

Things get further along using

spack install strumpack%apple-clang

but I get errors later related to linking to pre-existing g++ libraries on my laptop.

from strumpack.

I get a successful build when I execute.

spack install strumpack%apple-clang -mpi

For my current purposes I don't need MPI.

While I successfully ran an example using the spack installation, I also made a separate cmake based build. While everything compiled, I do get a runtime error on the example i tested.

The spack installation results in

I don't see what could be wrong here, that results in the Abort trap: 6. It seems to be related to the exception handling.
Do you see any differences in compilers used, compilation flags etc, between CMake and spack installs?

from strumpack.

Hi @pghysels . Apologies for the silence. I have been experimenting with different configurations. The problem I am encountering inspack is with scalapack and is due to inconsistencies with system libraries and the compiler.

To enable more control, I have successfully installed STRUMPACK with cmake. So I am personally good though I never got things to work with spack.
