googleearth & skype trouble

Hi!

 There seems to be a problem with some linux applications
eg.
googleearth and skype.

When I try to start them I get:
<program>: error while loading shared libraries:
/usr/lib/librt.so.1:
ELF file OS ABI invalid

My system:
FreeBSD oh-sub1.local 8.0-CURRENT FreeBSD 8.0-CURRENT #10:
Fri Dec 14
14:36:15 CET 2007     sperberoh-sub1.local:/usr/obj/usr/src/sys/OH-SUB1
 i386

[sperberoh-sub1] ~> sysctl -a |grep linux

skype-1.4.0.118_3,1
google-earth-4.3.7191.6508 (new version provided by the
maintainer)

Any idea what could be wrong to cause that problem?

Thanks in advance,
 Armin

I don't know about google earth, but skype & skype-devel
both require 
linux_base-fc6. Please follow the directions in UPDATING for
skype to 
properly upgrade.

If that's true then please fix UPDATING which mentions the
reqirement
only for the skype-devel.

The linux library is found but not used. And then the native
FreeBSD
one is got tried, hence the error occures. Sorry, but that
seems to be
a symptom of linux.osrelease=2.6.16 requirement for those
applications
to run.

Actually, this is a known problem with linux_base-fc4 and
2.4.2
emulation. It pops up on the mailinglists now and then so
it's starting
to become a faq.

One of the solutions is to create a softlink:

ln -f ../../lib/librt.so.1 /compat/linux/usr/lib/librt.so.1

That way, the linux compat open(2) syscall never returns the
FreeBSD
librt.so.1 and the linker eventually finds the 2.4.2
compatible version
/compat/linux/lib/obsolete/linuxthreads/librt.so.1.

Somebody should at this to a post-install target in the
port/package,
because /compat/linux/bin/ls and some others are affected as
well.

But does it really helps to skype or googleearth?

The case with linux bin/ls imho is an other one.  When you
run
/compat/linux/bin/sh and run any command you don't get linux
programs
running at the first place:
-----
% /compat/linux/bin/sh

bsam.ipt.ru$ uname -a
Linux host.ipt.ru 2.6.16 FreeBSD 7.0-STABLE #2: Fri Apr 18
01:36:58 MSD 2008 i686 i686 i386 GNU/Linux

bsam.ipt.ru$ file `which ls`
/bin/ls: ELF 32-bit LSB executable, Intel 80386, version 1
(FreeBSD), for FreeBSD 7.0 (700103), dynamically linked
(uses shared libs), FreeBSD-style, stripped
-----

Compare to:
-----
% sudo chroot /compat/linux /bin/sh

sh-3.2# uname -a
Linux host.ipt.ru 2.6.16 FreeBSD 7.0-STABLE #2: Fri Apr 18
01:36:58 MSD 2008 i686 i686 i386 GNU/Linux

I don't know, but they'll at least get past this problem.

Under linux sh you do get linux programs when they exist.
Running ls or
any shell script (like Maple/Matlab/... install and startup
scripts)
under linux /bin/sh currently does not work with fc4 and
osrelease=2.4.2.

This is not really a bug of linux compat, but is because of
the
following:

1. opening /path/to/somefile under linux compat first tries
   /compat/linux/path/to/somefile then /path/to/somefile.
2. linux binaries have two search paths for librt.so.1:
   /lib and /usr/lib.
3. fc4 has a librt.so.1 in /lib but it is rejected under
2.4.2
   emulation.
4. fc4 does not have a librt.so.1 under /usr/lib so when the
runtime
   linker tries this search path it ends up opening FreeBSD
   /usr/lib/librt.so.1 (because of point 1) and fails.

By adding a softlink in /compat/linux/usr/lib to the
librt.so.1 in
/compat/linux/lib, the linker doesn't open the FreeBSD
librt.so.1
anymore. Instead, under 2.4.2, it rejects this lib and then
tries an
internal search path /lib/obsolete/linuxthreads where it
finds the
correct version. Under 2.6.16 the softlink doesn't change
anything,
so imho this is something the fc4 port/package should deal
with.

Both file and which here are FreeBSD binaries so you're not
under
linux compat. FreeBSD file ends up opening FreeBSD /bin/ls.
If there
were a linux "file" binary, "file
/bin/ls" would open
/compat/linux/bin/ls.
