Trying crossdev -t i686-mingw32 results in failing (I'm using gcc 4.2.1): cross-i686-mingw32-gcc-stage1.log: configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.0+. Try the --with-gmp and/or --with-mpfr options to specify their locations. Copies of these libraries' source code can be found at their respective hosting sites as well as at ftp://gcc.gnu.org/pub/gcc/infrastructure/.

I would assume crossdev needs to build cross-i686-mingw32/{gmp,mpfr} too, so assigning to crossdev maintainers...
>I would assume crossdev needs to build cross-i686-mingw32/{gmp,mpfr} too Yeap, exactly. Building mpfr manually did the trick

During the Final linking stage, it hard-link to /usr/lib/libgmp.so, whose file format is the host x86 format. We need target format. Obviously the path should be "${ROOT}/usr/lib/libgmp.so" or "-L${ROOT}/usr/lib -lgmp". Later one would preferable. Actually, mpfr does provide one option at configure stage, either pass --with-gmp or --with-gmp-lib will append "-L${ROOT}/usr/lib -lgmp" to LDFLAGS variable. Seems that it will solve this problem with this, but unfortunately it's not the case. It still fail at final linking stage. Spend a few times, but still not catch the cause... clueless
Created attachment 186324 [details] cross emerge mpfr log
the cross-toolchains do not need a native gmp/mpfr. they are CBUILD depends. dropped --nodeps from default emerge options.
