this looks like you are trying to feed the pgi compiler flags that are meant for gcc preprocessor. thus there has to be something wrong in your make.sys file. [...] JH> On the wiki page, it says pgi v6.1 works (info from Paolo Cazzato) JH> http://www.quantum-espresso.org/wiki/index.php/Main_Page how old is that information. the PGI compilers are notoriously bad at 'modern' fortran 95 code, and Q-E has a slowly increasing amout of them, so if this statement is not recent (which i assume), then it is probably not applicable anymore. i would strongly suggest to first try compiling with the latest g95 _release_ (_not_ snapshot!) version and then try and revisit pgi and see if there is a significant difference (in speed _and_ results).
