Hi My english is not good (sorry) but I try to explain my problem
I have apache2.2.9 with modperl 2.0.4 static; I have some perl modules (development by me) with Sleepycat::DbXml library; when ran "make test" for its modules all is fine (I also develop the test); I also use mason (1.37). When i tried to acces some page generated for maso I gotten the next messages (log/error): /usr/local/apache2.2/bin/httpd: symbol lookup error: /usr/lib/perl5/vendor_perl/5.8.8/i686-linux/auto/Sleepycat/DbXml/DbXml.so: undefined symbol: _ZN5DbXml12XmlContainer10getManagerEv if I execute "ldd /usr/lib/perl5/vendor_perl/5.8.8/i686-linux/auto/Sleepycat/DbXml/DbXml.so" the output is: linux-gate.so.1 => (0xb7f25000) libdbxml-2.4.so => /usr/lib/libdbxml-2.4.so (0xb7b97000) libdb_cxx-4.6.so => /usr/lib/libdb_cxx-4.6.so (0xb7a4b000) libxerces-c.so.28 => /usr/lib/libxerces-c.so.28 (0xb7643000) libxqilla.so.4 => /usr/lib/libxqilla.so.4 (0xb726f000) libgcc_s.so.1 => /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libgcc_s.so.1 (0xb7263000) libc.so.6 => /lib/libc.so.6 (0xb7139000) libstdc++.so.6 => /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libstdc++.so.6 (0xb7055000) libm.so.6 => /lib/libm.so.6 (0xb7030000) libpthread.so.0 => /lib/libpthread.so.0 (0xb7019000) libnsl.so.1 => /lib/libnsl.so.1 (0xb7002000) /lib/ld-linux.so.2 (0x80000000) my distribution is gentoo... maybe the problem is caused by - duplicate libraries with different versions - or old libraries I updated my system and delete duplicate libraries, but the problem continue anybody can help me? .... where can investigate? another question is: why the problem is present only with apache? thanks in advance
