Bug 40947 – Emerging mtools with CFLAGS="-O3 -march=pentium4 -fprefetch-loop-arrays -funroll-loops -pipe" it crashes

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description davaeron 2004-02-09 01:06:27 UTC]

when i try to emerge mtools, I get errors like:

`-m486' is deprecated. Use `-march=i486' or `-mcpu=i486' instead.
codepage.c: In function `to_dos':
codepage.c:209: internal error: Floating point exception

1. CFLAGS="-O3 -march=pentium4 -fprefetch-loop-arrays -funroll-loops -pipe"
2. CHOST="i486-pc-linux-gnu"
3. USE="X -gtk -gnome -oss -apm -gpm -xmms alsa"
4. emerge mtools

Why CHOST="i486-pc-linux-gnu"?

Have you tried with i686-pc-linux-gnu? I suspect the problem is because it's building with -march=pentium4 and -m486 at the same time.

[Comment 2 SpanKY 2004-02-09 08:48:13 UTC]

yeah, using =march=pentium4 with a CHOST of i486 is pretty dumb ...

that may not be the cause of this bug, but you should research that first
