Error : unknown type name 'integer'

When I try to install WMAP likelihood in MontePython, I need to use clapack.h file. When I compile, the error in the attachment appears. Do you know how to fix the problem ? For example, include some header file or anything else ?

clapack is (an old release of) LAPACK converted from Fortran to C with the f2c converter - most likely you need to include f2c.h

Hi @westinhuang. I suggest you try to follow https://github.com/NIRALUser/CLAPACK for detailed instructions on how to install CLAPACK. I am closing this issue since it is unrelated to the code in LAPACK.
