Hello,
As with posters on this list from 7/15/06, 10/25/06 and 2/10/07, I am having
trouble with compat_freebsd and binaries that depend on shared libraries.
Everyone seems to have given up so far but sincerely want to get it working.
In short, launching a FreeBSD binary that depends on shared libraries reports:
# /emul/freebsd/usr/bin/ldd
/usr/libexec/ld-elf.so.1: /usr/lib/libc.so.4: mmap of entire address space
failed: Invalid argument
... even though they exist:
# ldconfig-freebsd -r|grep libc.so.4
13:-lc.4 => /usr/lib/libc.so.4
# find / -name libc.so.4 -print
/usr/local/emul/freebsd/usr/lib/libc.so.4
# ls -l /usr/local/emul/freebsd/usr/lib/libc.so*
lrwxr-xr-x 1 root wheel 9 Aug 4 00:44 \
/usr/local/emul/freebsd/usr/lib/libc.so -> libc.so.4
-r--r--r-- 1 root wheel 582928 Jan 21 2005 \
/usr/local/emul/freebsd/usr/lib/libc.so.4
Environment: OpenBSD 4.1 x86, FreeBSD 4.11 binaries
Now the checklist:
Is the sysctl enabled? Check.
sysctl -w kern.emul.freebsd=1
Off:
ksh: /emul/freebsd/usr/bin/ldd: Operation no permitted
On:
The error above
Did I copy in ldd-freebsd and ldconfig-freebsd as per the man page? Check.
Is the symlink to /emul/freebsd in place? Check.
ls -l /emul/
...freebsd -> /usr/local/emul/freebsd
Do I have a seemingly-good freebsd 4.11 bin installation? Check.
mount the cd...
cat /mnt/cdrom/bin.?? | tar zpxf - -C /usr/local/emul/freebsd
Did I create the empty shared library hints files? Check.
# touch /usr/local/emul/freebsd/var/run/ld-elf.so.hints
# touch /usr/local/emul/freebsd/var/run/ld.so.hints
Did I populate the cache with a safe set of paths that should work on both
OpenBSD and FreeBSD? Check. Along with only /usr/lib just in case
# ldconfig-freebsd /usr/lib /usr/local/lib /usr/X11R6/lib /usr/lib/compat
Did it do something? Check.
# ls -l /emul/freebsd/var/run
... 167 Aug 6 18:44 ld-elf.so.hints
Do statically-build binaries run? Check.
# ldconfig-freebsd -r
/var/run/ld-elf.so.hints:
search directories: /usr/lib:/usr/local/lib:...
0:-lcom_err.2 => /usr/lib/libcom_err.so.2
1...
Did I try FreeBSD's ldd? Check.
*Can't* It depends on shared libraries
Did I try OpenBSD's for what it's worth? Check.
# ldd `which ldd-freebsd`
/usr/local/bin/ldd-freebsd
libc.so.4 => not found (0x0)
Did I try the LD_LIBRARY_PATH environment environment over relying on the
shared library cache? Check.
export LD_LIBRARY_PATH=/usr/lib:/usr/local/lib:/usr/X11R6/lib
Did I compare the ldd output on a real FreeBSD 4.11 box? Check.
ldd `which ldd`
/usr/bin/ldd:
libc.so.4 => /usr/lib/libc.so.4 (0x2806a000)
Did I try a statically-built FreeBSD 4.11 world? Failed... may need a patch:
http://lists.freebsd.org/pipermail/freebsd-questions/2004-November/065954.html
make NOSHARED=yes buildworld
Did I turn off compat_linux in case it conflicts for some reason? Check.
Did I try variations on Linux's:
/lib/ld-linux.so.2 --library-path PATH EXECUTABLE
http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html
Failed: convention does not appear to be supported.
Did I try FreeBSD 5.5 binaries given that the man page referrs to 5.0? Check.
Failed... they all seem to have dynamic library dependencies.
Anything else I should try?
Does anyone have compat_freebsd working?
Many thanks,
Michael.
