Bug 149379 – [cross-mingw32/runtime] fails at mingwthrd.exp with illegal relocation type 28001 with -march=prescott

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Martin von Gagern 2006-09-28 00:27:30 UTC]

Encountered this when running "FEATURES=nostrip crossdev -t mingw32" trying to work around bug 148437. Error message reads like this:

try it with simpler CFLAGS ... like just -O2

"CFLAGS=-O2 CXXFLAGS=-O2 FEATURES=nostrip crossdev -t mingw32" works :-)
I'd never have thought -march likely to break such things.
Anyway, thanks a lot.
Probably should do some strip-flags in the ebuild to handle this automatically.

it is a bug in the toolchain; stripping flags just ignores the problem

Will this bug be addressed here by the Gentoo toolchain devs, or should I file a new bug somewhere else? If so, where?

If you are not going to fix it in the near future, a nice comment and a flag strip might still be a valid temporary workaround, so people won't have to override the flags every time they update their mingw cross compiler.

I get the same error :(

I don't have a prescott to try.  Could you try again with the newer versions of gcc and such that we have now?

Tried again, couldn't reproduce this any more, so I guess it's fixed. Thanks.
