(In reply to comment #0) so get it resolved upstream ?
yeah, it's mostly for tracking open bugs in regards to systemwide-clang.
Same problem here with latest wine version: 1.5.23 configure: error: You need gcc >= 4.4 to build Wine as 64-bit.
Upstream's configure.ac says AC_MSG_ERROR([You need gcc >= 4.4 or clang >= 3.8 to build Wine as 64-bit.])]) Is someone able to test with supported clang, both 32 bit and 64 bit?
I tested with ABI_X86="32 64" CC=clang CXX=clang++ With clang-3.8 (in tree but still masked), I had to disable the gcc bug check: * Checking for gcc-5-3 stack realignment compiler bug ... /usr/lib/gcc/x86_64-pc-linux-gnu/5.3.0/../../../../lib64/crt1.o: In function `_start': (.text+0x20): undefined reference to `main' x86_64-pc-linux-gnu-clang-3.8: error: linker command failed with exit code 1 (use -v to see invocation) * ERROR: app-emulation/wine-1.9.5::gentoo failed (pretend phase): * (no error message) Wine compilation itself went fine, and some test programs worked fine (with both wine and wine32

That's great to hear. If you are also able to, can you try compiling with ABI_X86="32 -64" with clang-3.5? I spoke to some wine developers who told me that they were compiling on OSX with a "heavily patched clang-3.5" for 32 bit wine. Would be nice to know if we supported that lower bound for 32 bit. Also, regarding the gcc bug check, that was a bug on my part :P Sorry about that.
With 32bit ABI, wine-1.9.5 compiled fine indeed with clang-3.5.0 (our current stable version). And notepad still worked :)
Wine should fully support clang now, and all of the compiler checks have been modified to handle gcc vs clang properly. Should be resolved in b64196973d3c0b1094647c7b331ddc12af364539.
