There are two issues here: 1) wine compiled with clang, and 2) wine (compil= ed=20 with gcc) running on clang compiled base. =20 Regarding 1), according to the wiki [1], wine does have stack alignment iss= ues=20 and some wine programs do not run when compiled with clang [2][3] and other= =20 bugs with clang cause freezing within wine [4][5]. The impression I get is= =20 that, using the work-a-round of stack realignment, wine does work to some=20 extent when compiled by clang. =20 Regarding 2) (which I believe Jan was referring to), when I have a gcc buil= t=20 world and just replace lib32 with clang built libraries I have winecfg and= =20 regedit launching but displaying black screens. Switching back to gcc buil= t=20 lib32 I get a working winecfg and regedit. This, to me, indicates a clang= =20 error somewhere. =20 The test was done on FreeBSD 9-Stable with: # clang --version =46reeBSD clang version 3.1 (branches/release_31 156863) 20120523 Target: x86_64-unknown-freebsd9.0 Thread model: posix Regards [1] wiki.winehq.org/Clang [2] (regedit) http://llvm.org/bugs/show_bug.cgi?id=3D9830 [3] (wineboot) http://llvm.org/bugs/show_bug.cgi?id=3D9844 [4] http://llvm.org/bugs/show_bug.cgi?id=3D9704 [5] http://llvm.org/bugs/show_bug.cgi?id=3D9707 --nextPart34669012.oYyl0Wpdqq Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEABECAAYFAlCUzFsACgkQUaaFgP9pFrKBHQCfYYozaPkx5SMvkmm+VPI8t+iA 1JIAnAq1cq2YTGL+Hbm+hr8pdLxhbHFD =m0nn -----END PGP SIGNATURE----- --nextPart34669012.oYyl0Wpdqq--
