next in thread | raw e-mail | index | archive | help
This is a step by step guide to get linux emulation to run
on AMD64 5.3-RC1 using the standard emulators/linux_base port.
This is pulled together from the previous work done by Tim Robbins and Francois Tigeot.
I posted this on freebsd-amd64 three days ago and no one has yet been opposed to this
procedure. If you update the linux-base Makefile it can still be tested before 5.3 RELEASE.
1.) Put these varaiables in the Kernel config file:
/usr/src/sys/amd64/conf/your_kernel_config_file
options LINPROCFS
options COMPAT_43
options COMPAT_LINUX32
Rebuild the kernel and install it !
2.) Edited /etc/fstab for linprocfs , add the line:
none /compat/linux/proc linprocfs rw 0 0
3.) Edit /etc/rc.conf and add the line:
linux_enabled="YES"
4.) Reboot.
5.) Patch /usr/ports/emulators/linux_base/Makefile with
Francois Tigeot's patch.
Put the patch below in /usr/ports/emulators/linux_base/patchfile
run:
# patch -p0 < patchfile

6.) Install linux_base
# cd /usr/ports/emulators/linux_base
# make install
7.) Fix the library searchpath for the linux Emulator to
find the linux X libraries. Brand some binaries as Linux binaries,
This is done in linux_base makefile for i386. These commands need to be
incerted in the linux_base Makefile ( for production use) in addition to the
patch under (5.)
# cd /usr/compat/linux
# brandelf -t Linux sbin/ldconfig
# brandelf -t Linux sbin/sln
# brandelf -t Linux sbin/rpm
# echo '/usr/X11R6/lib' > etc/ld.so.conf
# sbin/ldconfig
8.) Reboot again.
Install desired Linux apps and run.
