Hi,
I am having some trouble getting the linux emulation working
properly on my FreeBSD 2.1 system.
1.) got linux_lib-2.0 from /ports-current on 4/8/96
works fine with my original 2.1 kernel
2.) got -stable kernel source on 4/12/96
I needed some drivers anyway, and I wanted to get the most
recent bug fixes.
3.) rebuilt kernel with COMPAT_LINUX and LINUX_COMPAT options
(kernel config file included below)
4.) I load the Linux emulator module:
> modload -e linux_init /lkm/linux_mod.o
moLinux emulator installed
>modstat
TYPE Id Off Loadaddr Size Info Rev Module Name
EXEC 0 3 f171c000 0018 f1721000 1 linux_emulator
5.) got a good Linux binary (gzip) - (file is ZMAGIC, not QMAGIC)
The first few times I tried running this binary, it crashed my system.
There was no record of anything in /var/log/messages or on the system
console.
Then, today, I reinstalled linux_lib-2.0 and now it doesn't crash,
but instead I get this error message:
> ./gzip: can't load library '/libc.so.4'
ldconfig -r doesn't show it, so my ldconfig path could be wrong. It
is the default set in the rc files, since I didn't change it.
The strange thing is that after I learned how to use modload and
what module to load, I tried booting with my old 2.1 kernel
which I had also configured with COMPAT_LINUX and LINUX_COMPAT.
I tried running the same binary (gzip - QMAGIC) and it worked. In
fact doom even worked for a couple of seconds until it stopped and
told me "..unable to allocate shared memory.." - although I have
plenty of RAM (over 32M).
However, I do like the new kernel, and I would really like to get
it working with the linux emulator.
Any help would be greatly appreciated. Please email me at the
address below.
Thanks in advance,
