NERSC Cray Compilation Fail

[Alec Wills]

Hello,
When compiling with the Cray Fortran 9.0.0 or 9.1.0 on the NERSC cluster, an error occurs.

The configuration is generated with

------
./configure CXX=CC CC=cc FC=ftn --prefix=/global/homes/a/alecpw/progs/libpsml-1.1.8/haswell --enable-shared=no --with-xmlf90=/global/homes/a/alecpw/progs/xmlf90-1.5.4/haswell
------

and 'make' leads to

------

------

Using GNU compilers for the library doesn't yield any errors, but as the NERSC cluster is a Cray system, ideally I'd like to be able to compile everything with Cray compilers. Perhaps there is a fundamental disagreement between the compiler and the format of the code, but the Cray Fortran docs aren't very illuminating in that regard.

Best,
Alec

Dear Alec,

Sorry to be so late, but things are a bit hectic around here.

Note first that I have moved this issue to Gitlab:

    https://gitlab.com/siesta-project/libraries/libpsml/-/issues/2

(The bugs and questions interfaces in Launchpad will go away soon)

Second, I have released libpsml-1.1.10 in Gitlab:

    https://gitlab.com/siesta-project/libraries/libpsml/-/releases

This version removes the dependency on iso_varying_string (using instead allocatable character variables), so your problem might
have gone away...

I would be grateful if you could check this new version with your compilers.

 Best regards,

 Alberto
