[CP2K:2932] Illegal use of symbol gamma (cluster_methods.f90

[Teodoro Laino]

Hi,

this is clearly a bug in PGI compiler. In file cluster_methods.F there is a variable named gamma.
Unfortunately there is also a module named gamma. This is possible and correct. Unfortunately since 2006 (or even earlier) PGI refuses to accept this as a possibility and declares it a mistake (see your error message below).

Can't you use a different compiler? some free one? gfortran or g95 are 2 possible options that you can get without paying a cent.

Best,
Teo
