I've been trying to interface an example fortran code with python using f2py. f2py detects all installed fortran compilers & can be checked with the command f2py -c --help-fcompiler. The output of this shows the following default compiler options
IntelEM64TFCompiler instance properties:
archiver =

compiler_f90 =

ranlib =

The problem is, during compilation, ifort runs into an error since the f2py default compiler setting '-openmp' has been deprecated in the newer versions of iFort & it has to be replaced by '-qopenmp'. The compile time error is as shown below

Does anyone know how to change the default compile options auto-detected by f2py? Or else, is there a way to force f2py to compile with the user specified compile options & ignore the default values?
