Hello, windowmaker-0.91.0-r1 fails to compile, and I'm relatively sure that it's due to GCC4. Here's the error: i686-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I. -I../src -I/usr/include -march=athlon-xp -ggdb -O2 -pipe -O0 -c x86_specific.c -fPIC -DPIC -o .libs/x86_specific.o x86_specific.c: In function 'x86_mmx_TrueColor_32_to_16': x86_specific.c:107: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm' make[1]: *** [x86_specific.lo] Error 1 make[1]: Leaving directory `/var/tmp/portage/windowmaker-0.91.0-r1/work/WindowMaker-0.91.0/wrlib' make: *** [all-recursive] Error 1 emerge info: Portage 2.0.53 (default-linux/x86/2005.0, gcc-4.0.2, glibc-2.3.6-r2, 2.6.14-rc5-mm1 i686) ================================================================= System uname: 2.6.14-rc5-mm1 i686 AMD Athlon(tm) XP 2800+ Gentoo Base System version 1.6.13 distcc 2.18.3 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [disabled] ccache version 2.3 [disabled] dev-lang/python: 2.3.5-r2, 2.4.2 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=athlon-xp -ggdb -O2 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-march=athlon-xp -ggdb -O2 -pipe" DISTDIR="/mnt/aux/distfiles" FEATURES="autoconfig distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://gentoo.mirrors.easynews.com/linux/gentoo/" LANG="en_US.UTF-8" LC_ALL="en_US.UTF-8" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage /mnt/aux/portage-overlay" SYNC="rsync://rsync.namerica.gentoo.org/gentoo-portage" USE="x86 7zip aac acpi aim alsa ao apache2 async audiofile bash-completion bzip2 caps chroot crypt cups curl debug emacs emacs-w3 fam ffmpeg flac flood freetype gd gif gmp gstreamer idn imagemagick jack joystick jpeg lcms libsamplerate mad mhash mikmod mmap mmx mng mp3 mp4live mpeg mpeg2 mpeg4 mysql ncurses no-htdocs nocardbus nosendmail nptl nptlonly offensive ogg oscar pam pcre php png readline rtc sharedmem slang sndfile speex sse ssl szip theora tiff transcode udev unicode utf8 uudeview vidix vorbis webdav xvid zlib userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LDFLAGS, LINGUAS
Have you tested =x11-wm/windowmaker-0.92.0-r2? It works for me with gcc-4.1. Please reopen if 0.92.0-r2 bombs out too.
