The library was built using the FORTRAN Compiler in the MinGW
installation. The compile options were -O4
>From gnatmake, the link options were:
-largs -LW:\d-drive\LAPACK -llapack_WindowsXP -lblas_WindowsXP -LC:
\MinGW\lib -lg2c
The libraries refer to those created by G77 and we note the need for
some modules from g2c.
I have used both Float and Long_Float in instaniations.
Hope this helps.
