In the old distributed binary libmysqlclient.a file, we included the used
libgcc.a library to get less problems. With RPM:s we don't do this
and this could be the source for your problem.
Have you compiled apache with the same compiler you compiled Apache?
What kind of MySQL distribution are you using.
Are you linking with libmysqlclinet.so or libmysqlclient.a ?
Which glibc version are you using? The one that should work is:
shell> rpm -q glibc
If you are using binary RPM:s, one way out is to use source RPM:s for
MySQL and Apache.
