Description Dennis Schridde 2012-03-08 20:45:59 UTC 
I am using sys-devel/gcc-config-1.5.1 and sys-devel/crossdev-20120305 and am unable to set /usr/bin/gcc to execute the native compiler:
# rm /usr/bin/{gccgo,gcc,g++,cc,c++,cpp}
# gcc-config -l
 [1] i686-pc-mingw32-4.5.3 *
 [2] x86_64-pc-linux-gnu-4.6.2 *
# gcc-config 2
 * Switching native-compiler to x86_64-pc-linux-gnu-4.6.2 ... [ ok ]
# /usr/bin/gcc -dumpspecs | grep -A1 *libgcc:
*libgcc:
%{mthreads:-lmingwthrd} -lmingw32        -lgcc    -lmoldname -lmingwex -lmsvcrt

Reproducible: Always

Comment 1 Dennis Schridde 2012-03-08 22:32:11 UTC 
This might have something to do with crossdev not being able to finish "Emerging cross-mingw-runtime" (I manually unmasked a broken version) and hence not proceeding with "Emerging cross-gcc-stage2" when running "crossdev i686-pc-mingw32". If so, then crossdev should not be able to confuse gcc-config so easily.

Reason: I corrected the mingw-runtime compilation issue so that crossdev could finish including gcc-stage2 and now gcc seems to point to the correct compiler. This might be a coincidence, of course - would be interesting if someone can reproduce it.

I just tried to reproduce this by unmerging i686-pc-mingw32 and then breaking cross-mingw-runtime building again before trying to reinstall the mingw target, but it did not work.

For comparison, here my merge histories for the cross-i686-pc-mingw32 category and crossdev ("genlop crossdev", "genlop cross-i686-pc-mingw32/"):

/var/log/portage/cross-* does not contain information about invocations of crossdev, so I will have to guess from the merge times listed above:
It appears that sys-devel/crossdev-20120301 (built March 2nd) was the last version that built the complete toolchain before it broke (on March 3rd). Would be nice if someone could compare their times.
Comment 5 SpanKY gentoo-dev 2012-03-12 15:02:12 UTC 
what does `echo $GCC_SPECS` show ?

> what does `echo $GCC_SPECS` show ?
Here it is currently empty, but I have no idea what it contained when /usr/bin/gcc was still broken.

i.e. set but empty:
$ grep -z GCC_SPECS /proc/self/environ 
GCC_SPECS=
Comment 8 SpanKY gentoo-dev 2012-03-15 05:19:18 UTC 
well, re-open when you can make it break again
