Linking error with FetchContent #8

Closed puneetmatharu closed 3 years ago

puneetmatharu commented 3 years ago

I was previously working with an older version of your library that I forked and patched (for my own usage), but I thought I'd give your latest version a shot. My old version still works but the latest version doesn't. When I try to integrate the MUMPS project into my own using FetchContent, I encounter what appears to be a linking error (output provided below) at build time. Have you encountered this issue yourself at all, or know how to fix it?

For reference, I'm working on macOS and using a Clang compiler.

Thanks!

scivision commented 3 years ago

after (to the right of) libscalapack.a there should be linked libblacs.a

scivision commented 3 years ago

sometimes libblacs.a is inside libscalapack.a, sometime not.

I will update FindScalapack.cmake to look for the optional libblacs.a

scivision commented 3 years ago

Here is a standalone MUMPS Cmake FetchContent example: https://github.com/scivision/mumps-fetchcontent

It works on my MacOS with:

% cmake -B build
-- The C compiler identification is AppleClang 13.0.0.13000029
-- The Fortran compiler identification is GNU 11.1.0

Works an absolute treat -- thanks!
