Created attachment 50301 [details] make output When building GCC11 (last tested with 11-20210228) for Windows 32-bit with MinGW-w64 the build fails with undefined references to LC0/LC1/LC2/LC3. My build was done using the following configure command: ../configure --prefix=/R/winlibs32_stage/inst_gcc-11-20210228/share/gcc --build=i686-w64-mingw32 --host=i686-w64-mingw32 --with-pkgversion=MinGW-W64 i686-posix-dwarf, built by Brecht Sanders --with-tune=generic --enable-checking=release --enable-threads=posix --with-dwarf2 --disable-sjlj-exceptions --disable-libunwind-exceptions --disable-serial-configure --disable-bootstrap --enable-host-shared --enable-plugin --disable-default-ssp --disable-rpath --disable-libstdcxx-pch --enable-libstdcxx-time=yes --disable-libstdcxx-debug --disable-version-specific-runtime-libs --with-stabs --disable-symvers --enable-languages=c,c++,lto,objc,obj-c++,d --disable-gold --disable-nls --disable-stage1-checking --disable-win32-registry --disable-multilib --enable-ld --enable-libquadmath --enable-libada --enable-libssp --enable-libstdcxx --enable-lto --enable-fully-dynamic-string --enable-libgomp --enable-graphite --enable-mingw-wildcard --with-mpc=/d/Prog/winlibs32_stage/custombuilt --with-mpfr=/d/Prog/winlibs32_stage/custombuilt --with-gmp=/d/Prog/winlibs32_stage/custombuilt --with-isl=/d/Prog/winlibs32_stage/custombuilt --enable-install-libiberty --enable-__cxa_atexit --without-included-gettext --with-diagnostics-color=auto --with-libiconv --with-system-zlib --with-build-sysroot=/R/winlibs32_stage/gcc-11-20210228/mingw-w64 --enable-large-address-aware CFLAGS=-I/d/Prog/winlibs32_stage/custombuilt/include/libdl-win32 Note that I was able to build the 32-bit compiler once, but I had to disable fortran to work around this error. This is the second iteration where I try to build GCC 11-20210228 with the same version of GCC from the first iteration. Windows 64-bit builds work fine, so this error is limited to Windows 32-bit. Any idea what causes this?
This looks like an issue with the base compiler, could you post the output of 'gcc -v'? Could you also avoid forcing -O2 during stage #1, i.e. use the default -O0 or only -O1?
Created attachment 50302 [details] gcc -v
> gcc -v No, what's needed is the output for the *base* compiler, i.e. the compiler you start from, not the compiler you're building.
OK, I missed that you're explicitly rebuilding the compiler with itself after having bootstrapped it first... You're on your own here, no one does that.
*** Bug 97618 has been marked as a duplicate of this bug. ***
Anyway, in that case you want to attach here the preprocessed source on which some undefined references to LC* appear and state exact gcc options that were used to compile that, so that others can try to reproduce it e.g. with cross-compilers.
Maybe dup of PR99872 ?
Recently released version 11.1.0 does build for Windows 32-bit with MinGW-w64 without issues.
