hi, I use Redhad 9.0, Pwlib 1.6.6, Openh323 1.13.5, Oh323 0.6.3a. The installation of these package are ok. But when loading oh323, there is error: [chan_oh323.so]Jul 13 12:56:47 WARNING[1074464512]: loader.c:240 ast_load_resource: /usr/local/lib/liboh323wrap.so: undefined symbol: _ZTI14PAbstractArray Jul 13 12:56:47 WARNING[1074464512]: loader.c:421 load_modules: Loading module chan_oh323.so failed! I have asked this question in the mail list before. Someone solved the problem. He said it's due to a problem with redhat 9.0 and need to use the latest glibc and libssl. But the latest version of glibc is 2.3.2, and the glibc in redhat 9 is also 2.3.2. I tried to download the glibc and comply it. But still can't work. So where is the problem? Could you give me more details to help me solv this problem? Thanks a lot Rui ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca
