Hi all, I have this function defined twice. One in the libgcc2.c file and one in gcc/config/arm/ieee754-df.S __floatdisf

I have problem during compilation of a arm soft float toolchain. Is there any fix? Regards Michael

The build system should only be using the latter. What configuration are you using? And what version of gcc?

FSF gcc distributions aren't set up to do soft-float on arm-linux by default, so this must be a problem with the cross-tool patches. You'll need to talk to the cross-tool authors (try cross-gcc@sourceware.org).
