I just thought I'd mention that Soren's linux compatibility
works just fine in -stable. Thanks David!!
-stable is missing the directory /usr/src/lkm/linux. Can we
add it from the FreeBSD-current source tree?
I'll look at writing a man page, but meanwhile here's my
notes. Rich
Running Linux binaries on FreeBSD 2.1 (aka -stable):
Install a kernel whose configuration file contains:
options "COMPAT_LINUX"
options SYSVSHM
[you need SYSVSHM if you test the emulator using xdoom.]
Get a copy of the directory /usr/src/lkm/linux from the
FreeBSD-current source tree.
Install the loadable kernel module (LKM) and /usr/bin/linux:
cd /usr/src/lkm/linux
make all install
load the LKM (as root):
linux
get the linux runtime libraries:
mkdir /compat/linux
cd /compat/linux
ncftp ftp.freebsd.org:pub/FreeBSD/2.0.5-RELEASE/xperimnt/linux-emu/linux-emu.tar.gz
tar xzf linux-emu.tar.gz
rm -rf usr lkm
Note that the README there says to unpack linux-emu.tar.gz
in the root directory. The emulator will work just fine if
unpack it in /compat/linux instead. Also, you only need the
shared libraries from this tar archvive since you've already
installed the LKM and /usr/bin/linux.
To test it, install linux doom:
ncftp ftp.freebsd.org:pub/FreeBSD/2.0.5-RELEASE/xperimnt/linux-emu/linux-doom-1.8.tar.gz
tar xzf linux-doom-1.8.tar.gz
cd doom-1.8
./xdoom
