I am trying to build a 32-bit windows toolchain by: "crossdev --target i686-w64-mingw32". Command fails at 'Emerging cross-gcc-stage2' step, with message: * error: gcc failed :( Reproducible: Always Steps to Reproduce: 1. launch command: crossdev --target i686-w64-mingw32 2. 3. Actual Results: compilation fails Expected Results: toolchain has to be built

I recommend you retry with more saner *FLAGS and disabling LTO stuff.
>--with-build-config=bootstrap-lto seems odd here. Is USE=lto enabled for it?
(In reply to Tee KOBAYASHI from comment #4) > I recommend you retry with more saner *FLAGS and disabling LTO stuff. Cross package constructs FLAGS by its own, according to log it uses: * CFLAGS="-O2 -pipe" * CXXFLAGS="-O2 -pipe" Did you mean these flags or some other? (In reply to Sam James from comment #5) > >--with-build-config=bootstrap-lto > seems odd here. Is USE=lto enabled for it? Yep, lto is enabled in USE, tried to re-run command w/ flag disabled, got same error: gcc failed :(
Ah, I forgot *FLAGS are not inherited from build host. They seem quite sane.

I suggest that you retry not only building gcc-stage2, but also mingw64-runtime, or preferably everything from start, with LTO disabled. I'm not sure where this LTO stuff came from, if the build host *FLAGS are not inherited to a cross environment.

Tried to unmerge runtime cross-i686-w64-mingw32/mingw64-runtime, disabled lto and re-run compilation -- got same error. Will forcibly rebuild all dependencies without lto, according to graph, and re-try.
Did you manage to solve this? I am running into this too.
(In reply to Kostadin Shishmanov from comment #10) > Did you manage to solve this? I am running into this too. Nope, just found that 32-bit env is not required for my tasks, so left at as is, since rebuilding of everything without lto doesn't help.
I managed to fix it by doing: crossdev --clean --target i686-w64-mingw32 crossdev --clean --target x86_64-w64-mingw32 Then, I removed every flag from my make.conf except for "-march=native -O2 -pipe" After that I tried building mingw again with crossdev --b 2.38 --target i686-w64-mingw32 crossdev --b 2.38 --target x86_64-w64-mingw32 and to my surprise it worked with no issues.
