[mpich-discuss] Compilation with AOCC - clang-8 errors unsupported options '-soname', etc.

With `—disable-shared` you didn’t solve the problem, you avoided the problem. From your `./libtool —tag=FC —config`, apparently libtool has no idea about `flang`, so it doesn’t know how to pass on the linker flags. It is strange that they took a blank default for `wl`.
`flang` is quite new, until libtool gets updated, the only solution is to patch libtool. To do it manually, if you open the libtool script (after configure), if you see `wl=‘’`, then it probably should be changed into `wl=‘-Wl,’`.

Hi Thomas,
I thought I had "solved" the problem by using --disable-shared --enable-static, but then I have other issues after (with hdf5, netcdf, etc.), so back to square one...
You will find below what the ./libtool --tag=FC --config command gives, is that of any help?

I think
