--Boundary-00=_OKYXC+kkn1fOkqy Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Content-Disposition: inline I finally manage to build QEMU snapshot on FreeBSD/amd64 6-CURRENT. There's ports/emulators/qemu but it doesn't build on AMD64 for several reasons, i. e., QEMU and FreeBSD are both fast moving targets (esp. src/lib/msun), some long double math functions don't exist on FreeBSD, GCC in base system doesn't build QEMU because of several optimization bugs specific to AMD64, etc. 1. Install GCC 3.4 from ports. Anything newer than 20050316 should work. (Theoretically you can use gcc40 newer than 20041127 but not verified. Actually I am using patched version of src/contrib/gcc. ;-) 2. Install following dependencies from ports: devel/gmake (of course) net/samba devel/sdl12 I believe samba is optional but sdl12 is not. It doesn't work without SDL because `-nographic' option is broken. I believe it is an upstream bug (related to FreeBSD's pty or termios, i. e., fail to get correct term size and segfault) but I couldn't pin-point the culprit yet. In fact, I didn't bother too much because SDL worked just fine. ;-) 3. Get the latest QEMU source from: http://www.dad-answers.com/qemu/ The file name is something like qemu-snapshot-*.tar.bz2. 4. Extract the tarball, chdir to it, and do the following: mkdir -p bsd/amd64 patch -p0 < ${PATCHDIR}/qemu-snapshot-fbsd.diff patch -p0 < ${PATCHDIR}/qemu-libmath-amd64.diff ./configure -cc=${GCC_BIN} gmake gmake install ${PATCHDIR} is where the attached patches are saved and ${GCC_BIN} is gcc path, e. g., /usr/local/bin/gcc34 for GCC 3.4.4 and /usr/local/bin/gcc40 for GCC 4.0.0, etc. I was able to run DragonFly 1.2 CD-ROM on i386 emulation (qemu) and Mandrake Linux 10.2rc1 for amd64 on x86-64 emulation (qemu-system-x86-64). ppc (qemu-system-ppc) and sparc (qemu-system-sparc) emulators are not tested. Enjoy, Jung-uk Kim Note 1: The limitations of this patch should be the same from ports because large portion was taken from it: http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/ports/emulators/qemu/pkg-message?rev=1.7&content-type=text/plain Note 2: qemu-libmath-amd64.diff contains C99 long double math functions taken from glibc-2.3.5 and modified for FreeBSD/amd64: http://ftp.gnu.org/gnu/glibc/ http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/?cvsroot=glibc rintl() sysdeps/i386/fpu/s_rintl.c atan2l() sysdeps/i386/fpu/e_atan2l.c sqrtl() sysdeps/i386/fpu/e_sqrtl.c llrintl() sysdeps/x86_64/fpu/s_llrintl.S lrintl() sysdeps/x86_64/fpu/s_llrintl.S sinl() sysdeps/x86_64/fpu/s_sinl.S cosl() sysdeps/x86_64/fpu/s_cosl.S tanl() sysdeps/x86_64/fpu/s_tanl.S logl() sysdeps/x86_64/fpu/e_logl.S powl() sysdeps/x86_64/fpu/e_powl.S remainderl() sysdeps/x86_64/fpu/e_remainderl.S Just enough to compile QEMU snapshot until we complete C99 project. ;-) Similarly you can add other architectures under bsd/${MACHINE_ARCH}. --Boundary-00=_OKYXC+kkn1fOkqy Content-Type: text/x-diff; charset="us-ascii"; name="qemu-libmath-amd64.diff" Content-Transfer-Encoding: 8bit Content-Disposition: attachment; filename="qemu-libmath-amd64.diff" diff -urN bsd.orig/Makefile bsd/Makefile --- bsd.orig/Makefile Wed Dec 31 19:00:00 1969 +++ bsd/Makefile Wed Apr 13 12:43:36 2005 @@ -0,0 +1,22 @@ +SRCS= ${MACHINE_ARCH}/e_atan2l.c \ + ${MACHINE_ARCH}/e_logl.S \ + ${MACHINE_ARCH}/e_powl.S \ + ${MACHINE_ARCH}/e_remainderl.S \ + ${MACHINE_ARCH}/e_sqrtl.c \ + ${MACHINE_ARCH}/s_cosl.S \ + ${MACHINE_ARCH}/s_llrintl.S \ + ${MACHINE_ARCH}/s_lrintl.S \ + ${MACHINE_ARCH}/s_rintl.c \ + ${MACHINE_ARCH}/s_sinl.S \ + ${MACHINE_ARCH}/s_tanl.S + +OBJS= ${SRCS:R:S/$/.o/} + +all: libmath.a + +libmath.a: ${OBJS} + rm -f $@ + ${AR} rcs $@ ${OBJS:T} + +clean: + rm -f ${OBJS:T} libmath.a diff -urN bsd.orig/amd64/e_atan2l.c bsd/amd64/e_atan2l.c --- bsd.orig/amd64/e_atan2l.c Wed Dec 31 19:00:00 1969 +++ bsd/amd64/e_atan2l.c Tue Apr 12 18:53:57 2005 @@ -0,0 +1,16 @@ +/* + * Written by J.T.
