The first question is always where's the manual :)
Niggle: The first nmake stops with an error that Core.obj is not found. Workaround: once you get this error do the following: cd Basic\Core nmake Core.xs del getdev.pl # this one is important, otherwise you get a # circular Makefile dependence! cd ..\.. perl Makefile.PL # with F77CONF=win32/win32f77.pl if you want slatec nmake Now it should work. Finish with nmake test Should pass everything but test 6 in conv.t. Safe to ignore for now.
