I've bumped into a library I can't resolve and I must have a disconnect
in how the linux_compat works because I can't see how it could be
solved.
I have the following:
* compat_linux enabled in the kernel,
* /usr/ports/emulators/linux_base_fc7
* sysctl kern.fallback_elf_brand=3
* rpm2cpio to alter rpms
* cpio to create the directories and place the files where they
belong in /compat/linux.
I have a program that now has all it's libraries resolved but one in
preparation to attempt to run the Linux Quickbooks install on FreeBSD.
The ldd output, prior to installing /usr/ports/devel/fam (a required
shared
library) looks like this.
ldd ./opt/qbes7/util/qbmonitord
./opt/qbes7/util/qbmonitord:
libfam.so.0 => not found
libpthread.so.0 => /lib/libpthread.so.0 (0x28072000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x28088000)
libm.so.6 => /lib/libm.so.6 (0x28171000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x28198000)
libc.so.6 => /lib/libc.so.6 (0x281a4000)
/lib/ld-linux.so.2 (0x28054000)
I install fam to get rid of the not found, perform the following link:
ln /usr/local/lib/libfam.so.0 /compat/linux/lib/libfam.so.0
and then I get this:
ldd ./opt/qbes7/util/qbmonitord
./opt/qbes7/util/qbmonitord:
./opt/qbes7/util/qbmonitord: error while loading shared libraries: /
lib/libfam.so.0: ELF file OS ABI invalid
./opt/qbes7/util/qbmonitord: exit status 127
which kind of makes sense since this library is not a linux library.
I'd read
that I don't need to brandelf -t linux a library but I tried that
anyway,
realizing it was likely meaningless (or harmful). It didn't help of
course.
My next thought was to try and get a libfam.so.0 binary from a linux
distro
but stopped when it occurred to me that it would be illogical since
fam uses
kqueue on FreeBSD rather than something called imon. imon is not
available
for FreeBSD so a linux version shouldn't be able to function if it
expects that. On
FreeBSD, fam configures itself to not use imon.
What is the appropriate course of action to get a linux flavor shared
library
for fam (or anything which runs into such conflicts) that will work
on FreeBSD
yet be recognized as suitable for linux under the compat mode?
