It seems that SLS has for some reason distributed a testing only version of
the libc library (I think because of some networking problems with 4.4.1).
libc.so.4.4.2 is NOT a public release. The messages you are getting is
because your stubs (.sa files) and DLL's (.so files) do not match version
numbers.
You can tell what the stub version number by doing the following:
% nm /usr/lib/libc.sa | grep "[DU] ___libc"
this should give you multiple lines something like
U ___libc_4_402
U ___libc_4_402
U ___libc_4_402
This means your stub is version 4.4.2.
Now look in your /lib directory and see what your libc.so.4 file is linked
to. It is more likely than not linked to a DLL library version lower than
the stub library .sa - hence the warning mesage when a you compile
something.
The idea is to make sure both these versions numbers are the same so what
you compile gets dynamically linked to the correct version of the DLL at
run-time. In other words you probably need the new libc.so.4.4.2.
Please read the GCC-FAQ on sunsite.unc.edu /pub/Linux/docs/faqs for more
information.
