Hi,
I've been scouring the handbook, and the general and emulation archives but
haven't seen a resolution for this:
I *am* able to run certain linux ELF binaries.
I'm having linux compat problems in 2.2.8 wrt dynamic libs.
I have installed the linux_lib and linux_devel stuff from the 2.2.8 CD.
The first symptom is a bad magic complaint in the lib:
bad magic number in "./../J-HAPI/lib/linux/libjhapi.so" (libjhapi.so)
I tracked down the instructions for setting up linux_lib
(http://www.freebsd.org/handbook/handbook310.html#655)
and got to the step where I run
/compat/linux/usr/bin/ldd
on itself to verify that things work. It fails due to not mapping
/lib -> /compat/linux/lib, so I kludged this link by hand.
The above 'ldd' is a script that tries to actually invoke
ld-linux.so.2 --verify $file
This makes no sense to me, but doing so definitely gives an error:
bash: /lib/ld-linux.so.2: cannot execute binary file
(Same as any wrongly attempted execution of any .so.)
This happens also if I use the /compat/linux/bin/bash, and occurs
whether I modload /lkm/linux_mox.o, or run a kernel with COMPAT_LINUX
enabled. I've tried brandelf'ing some of the .so's with no effect.
I didn't try branding everything under /compat/linux though.
Since this is for a production system, I currently don't have the
option of upgrading to 3.1.
Does anyone have a clue what I can do to get .so format recognized?
Thanks!
k.
(If you know the solution to exist within the archives, can you give
me an explicit pointer please - As mentioned, I've already spent
quite a bit of time in there, so if I missed it, I need my nose stuck
directly into it. Thanks...)

This seems correct, however, correctness doesn't pay the bills. We need to
right size and get our arms around the inappropriate behavior.
