Command was: # crossdev x86_64-pc-mingw64 I edited the make.conf slightly to use -O2 instead of -Os and I set MARCH_TUNE=-march=generic, which was unset before.
The error happens in: const struct gcc_options global_options_init = { … 0, /* TARGET_NOP_FUN_DLLIMPORT */ HAVE_GAS_ALIGNED_COMM, /* use_pe_aligned_common */ 0, /* ix86_preferred_stack_boundary_arg */ … }; Apparently HAVE_GAS_ALIGNED_COMM should be defined to some value (probably 0 or 1) depending on the setup. This seems to stem from gcc-4.7.2/gcc/configure.ac:3604: case $target_os in cygwin* | pe | mingw32* | interix*) # Recent binutils allows the three-operand form of ".comm" on PE. This Which should probably be: cygwin* | pe | mingw* | interix*) There are probably similar problems in the following lines: case $host in 1453: *-*-mingw32*) use_cxa_atexit=yes case $host_os in 1656: win32 | pe | cygwin* | mingw32* | uwin*) if test "x$enable_win32_registry" != xno; then [case $target_os in 2565: win32 | pe | cygwin* | mingw32* | uwin*) # Need to check that we generated the correct relocation for the
I reported the issue upstream: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55886
Created attachment 338806 [details, diff] gcc-4.7.2-define-have_gas_aligned_comm.patch Attached patch fixes this error. However, I ran into another problem where build/./gcc/include-fixed/stdio.h was messed up and created another GCC bug about it. See also: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56311
Created attachment 338808 [details, diff] gcc-4.7.2-define-have_gas_aligned_comm.patch (for configure) Attached patch fixes configure directly, because gcc does not run eautoreconf.
Created attachment 338892 [details, diff] gcc-4.7.2-inclhack-hpux10_stdio_declarations.patch (In reply to comment #6) > Attached patch fixes this error. However, I ran into another problem where > build/./gcc/include-fixed/stdio.h was messed up and created another GCC bug > about it. Attached patch fixes this issue for me. Since Gentoo does not support HP-UX, it should be safe to apply.
Created attachment 338894 [details, diff] gcc-4.7.2-inclhack-hpux10_stdio_declarations.patch (for fixincl.x) Attached patch fixes the generated fixincl.x code directly, because the build-system does not automatically regenerate it.
With both (or rather: all 4) patches applied, gcc-4.7.2 builds for x86_64-pc-mingw64 here.
I ran into more issues when building libstdc++-v3 for this target. Patches attached. See also: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56332

So now that you're using the right triplet, how much of this is valid?
(In reply to comment #15) > So now that you're using the right triplet, how much of this is valid? x86_64-w64-mingw32 and i686-w32-mingw32 build without any of the patches. Though I now think that maybe crossdev could warn about the wrong triplets...
(In reply to comment #16) there is, almost literally, no way for crossdev to know what is "valid". that is entirely up to the toolchain packages (and their versions). binutils supports some obscure targets than gcc/glibc doesn't. add in the huge variety of naming conventions. i've made "mingw64" into an alias for "x86_64-w64-mingw32".
