When building boot0 it tries to use the following 'ld' command: x86_64-gentoo-freebsd6.1-ld -static -N --gc-sections -nostdlib -m elf_i386_fbsd -e start -Ttext 0x7c00 -o boot1.out boot1.o that throws the following error: x86_64-gentoo-freebsd6.1-ld: cannot open linker script file ldscripts/elf_i386_fbsd.xbn: No such file or directory The error is because '-nostdlib' is passed to ld as parameter, but is needed to not use a default stdlib. Checking ../Makefile.inc we can see: .if ${MACHINE_ARCH} == "amd64" CFLAGS+= -m32 LDFLAGS+= -m elf_i386_fbsd AFLAGS+= --32 .endif that is forcing "amd64" to use the "elf_i386_fbsd" BFD and it cannot by found. I think the BFD should be decided by LD at compile time. With the patch attached in the next message I removed it. A "file" under some /boot files shows that is an x86 boot sector with the patch applied: root@localhost boot # pwd /boot root@localhost boot # for x in "boot boot0 boot0sio boot1 boot2"; do file ${x}; done boot: x86 boot sector; partition 4: ID=0xa5, active, starthead 0, startsector 0, 50000 sectors, code offset 0x3c, reserved sectors 0, Media descriptor 0x0, reserved 0x16, dos < 4.0 BootSector (0x1f) boot0: x86 boot sector boot0sio: x86 boot sector boot1: x86 boot sector; partition 4: ID=0xa5, active, starthead 0, startsector 0, 50000 sectors, code offset 0x3c, reserved sectors 0, Media descriptor 0x0, reserved 0x16, dos < 4.0 BootSector (0x1f) boot2: data root@localhost boot # Related information: root@localhost boot0 # gcc -v Reading specs from /usr/lib/gcc/x86_64-gentoo-freebsd6.1/3.4.6/specs Configured with: /var/tmp/portage/gcc-3.4.6-r1/work/gcc-3.4.6/configure --prefix=/usr --bindir=/usr/x86_64-gentoo-freebsd6.1/gcc-bin/3.4.6 --includedir=/usr/lib/gcc/x86_64-gentoo-freebsd6.1/3.4.6/include --datadir=/usr/share/gcc-data/x86_64-gentoo-freebsd6.1/3.4.6 --mandir=/usr/share/gcc-data/x86_64-gentoo-freebsd6.1/3.4.6/man --infodir=/usr/share/gcc-data/x86_64-gentoo-freebsd6.1/3.4.6/info --with-gxx-include-dir=/usr/lib/gcc/x86_64-gentoo-freebsd6.1/3.4.6/include/g++-v3 --host=x86_64-gentoo-freebsd6.1 --build=x86_64-gentoo-freebsd6.1 --disable-altivec --disable-nls --with-system-zlib --disable-checking --disable-werror --disable-libunwind-exceptions --enable-multilib --disable-libgcj --enable-languages=c,c++ --enable-shared --enable-threads=posix --enable-__cxa_atexit Thread model: posix gcc version 3.4.6 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9) root@localhost boot0 # root@localhost boot0 # ld -nostdlib -V GNU ld version 2.17 Supported emulations: elf_x86_64_fbsd elf_i386_fbsd elf_x86_64 elf_i386 root@localhost boot0 # root@localhost boot # emerge --info Portage 2.1 (!/usr/local/amd64-fbsd-portage/profiles/default-bsd/fbsd/6.1/amd64, gcc-3.4.6, freebsd-lib-6.1-r0, 6.1-RELEASE amd64) ================================================================= System uname: 6.1-RELEASE amd64 amd64 Gentoo Base System version 20060420 ccache version 2.4 [enabled] app-admin/eselect-compiler: [Not Present] dev-lang/python: 2.4.3-r1 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: 2.4-r2 dev-util/confcache: [Not Present] sys-apps/sandbox: [Not Present] sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2 sys-devel/binutils: 2.17 sys-devel/gcc-config: 1.3.13-r2 sys-devel/libtool: 1.5.22 virtual/os-headers: 6.1 ACCEPT_KEYWORDS="amd64-fbsd ~amd64-fbsd" AUTOCLEAN="yes" CBUILD="x86_64-gentoo-freebsd6.1" CFLAGS="-march=k8 -O2 -pipe" CHOST="x86_64-gentoo-freebsd6.1" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/env.d /etc/gconf /etc/revdep-rebuild /etc/terminfo" CXXFLAGS="-march=k8 -O2 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig ccache distlocks metadata-transfer sfperms strict" GENTOO_MIRRORS="http://linuv.uv.es/mirror/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude='/distfiles' --exclude='/local' --exclude='/packages'" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/amd64-fbsd-portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="amd64-fbsd X berkdb crypt cups gdbm gif ipv6 jpeg ncurses ogg oss pam perl png python readline ssl tcpd truetype usb xml xorg xv zlib elibc_FreeBSD kernel_FreeBSD userland_BSD" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, LINGUAS, PORTAGE_RSYNC_EXTRA_OPTS
Created attachment 92169 [details, diff] The patch drops LDFLAGS in ../Makefile.inc
Victor this patch does not seem to apply cleanly, can you take a look for one that applies clean on boot0 ebuild?
The problem resides in "-m32" flag of GCC. For now in FreeBSD/Amd64 systems cannot be used due its early development stage so we need boot0-static (see #141135).
this has been fixed long ago afaik
