Dear All, I'm trying to use f2py in order to convert a fortan-file fonctions_f90.f90 I apply the following command line f2py -m fonctions_f90 --fcompiler=pg -c fonctions_f90.f90 Everything seems to be well, until this error appears : Pgcc: /tmp/tmp7RvKeA/src.linux-x86_64-2.5/fortranobject.c Pgcc-Error-Unknown switch: -fno-strict-aliasing Pgcc-Error-Unkown switch: -fwrapv Pgcc-Error-Unkown switch: -Wall Pgcc-Error-Unkown switch: -Wstrict-prototypes Does anyone could explain me what append and how to fix this problem ? Thanks for help. -- Aurelien
