Hi Leute,

was machen die USE Flags (-n32) (-n64) und fortran?
Diese USE Flags gehören zum gcc 4.4.4-r2.
Warum brauche ich das USE Flag fortran? Was machen -n32 und -n64?

Gruss Joerg

Code:
$ quse -D n32
 local:n32:dev-libs/klibc: Force klibc to 32bit if on mips64 if not n32 userland
 local:n32:sys-devel/gcc: Enable n32 ABI support on mips
 local:n32:sys-process/procps: Enable n32 ABI support on mips
$ quse -D n64
 local:n64:sys-devel/gcc: Enable n64 ABI support on mips
$ quse -D fortran
 global:fortran: Adds support for fortran (formerly f77)

Was fortran und mips sind sagt dir wikipedia. Wenn ein Paket fortran braucht, wird dir das schon mitgeteilt. Wirklich weh tut es nicht, wenn du es gleich mitbaust, bei aktuellen Festplattenkapazitäten und CPUs.

Bei mir wollte Digikam fortran haben, weil das blas (Mathelib) nutzt und diese Lib wiederum in Fortran implementiert ist.
