[PyKDE] undefined symbol: __pure_virtual

[Aleksey Naumov]

Dear PyQt users,

I have a problem installing PyQt-2.0: it compiles ok, but 'make install'
complains about
'undefined symbol: __pure_virtual' in libsip.so.3

I run RedHat-6.2 on a 686 intel system. Everything (Qt-2.2.0, sip-2.0.1,
PyQt-2.0) was compiled
with the same compiler - gcc-2.95.2. There can be no conflict with
previous versions
of sip or PyQt (none were installed on this machine). I've repeated the
whole installation
process (sip, PyQt) from scratch (uncompress, apply patches 1 & 2 to
PyQt, though that shouldn't
matter, configure, make) - but with the same result!

Qt-2.2.0 is installed in /usr/local/qt and all examples are working ok.

I include 2 outputs: (1) from 'make install' of PyQt and (2) 'configure'
and 'make install' output
for sip (because the problem seems to be with libsip)

Any insight would be greatly appreciated!

Thank you

Aleksey

Libraries have been installed in:
   /usr/local/lib/python1.6/site-packages

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
