Hi all,
I have three g++ versions installed. Debian's native g++-4.3 and
g++-4.4 both use /usr/lib/libstdc++.so.6.13, while
/usr/local/bin/g++-4.5 needs /usr/local/lib64/libstdc++.so.6.14.
If I use CXX=/usr/local/bin/g++-4.5 at configure time, executables
are linked against /usr/lib/libstdc++.so.6.13, which is not what
I want. What is the approved Cmake Way for insuring that executables
using g++-4.5 link against libstdc++.so.6.14?
The selection of libstdc++ takes place by the usual library searching
mechanism, so you must ensure that /usr/local/lib64/libstdc++.so.6.14
takes precedence over /usr/lib/libstdc++.so.6.13 for runtime linking.
Use ldconfig in connection with /etc/ld.so.conf, the LD_LIBRARY_PATH
environment variable et al., or pass appropriate rpath settings to
the linker, whatever suits your needs best.
Regards,
Michael
