Here is the output:

Which file do I have to check?
As far as I understand, libocc.a is OK.

Dima@home ~/opencxx.pch
$ cd .libs/

Dima@home ~/opencxx.pch/.libs
$ nm libocc.a

empty_libocc.o:
00000000 b .bss
00000000 d .data
00000000 N .stab
00000000 N .stabstr
00000000 t .text

I do not know why it is.

This is libtool-wrapper, which will hand off execution
to one of the two real versions listed above, depending
on the contents of configure.in/configure.ac.  Since the
wrapper was called from within a directory in which those
files are not found, this generic 'version' message is
displayed.
