Re: [Gretl-users] lapack/gretl on 64 sabayon/gentoo

This, together with customer expectations, means that FORTRAN-77 implementations will generally leave INTEGER as a 32-bit type, even on 64-bit platforms." I think it's worth trying to tackle the issue the other way round: it may be that the "integers" being passed from gretl to lapack on your system are too big, not too small. The size of "integer" is controlled by a header in the lib/src directory of gretl: it used to be called f2c.h but in current CVS it's renamed as gretl_f2c.h (to try to avoid confusion with any other f2c.h that might be on the system). In that file you'll find: typedef long int integer; Try changing this to typedef int integer; and rebuilding gretl. Allin.
