[Q-e-developers] Compilation of QE with PGI 15

[Filippo SPIGA]

Hello Martin,

ok I understand now. So what GCC are you using? I saw this behaviour already while playing with a ARM64 platform some time ago so my guess is you are using GCC 5.2.0 or even newer. Am I right?

Only because the PGI compiler cannot do the preprocessing itself, the additional cpp step is added. However, when called with the "-C" the gcc C preprocessor adds a comment in C format, which then cannot be compiled by the PGI compiler.
