There are 3 parts with my application. Server, Client library and client The whole application (Server & client library) is compiled with GCC4.1.2 & libstdc++.so.6.0.8. in RHEL5.2 PC and package has got created After install the package with one more PC which is also RHEL5.2 (GCC4.1.2 & libstdc++.so.6.0.8), I wrote a client code. The client throws exception. 'Terminate called after throwing instance of 'JTCSystemCallException' Aborted' [Note : A small check was, I have copied libstdc++.so.6.0.3 from RHEL4 PC - Now the client is working fine - It is not throwing any exception -But it didn't retrieved any data - Reason is server didn't boot up - Because of the copy (libstdc++.so.6.0.3) – Thatz the correct behavior.] But why the same client is not able to up with the libstdc++.so.6.0.8? Is there any option missed out? Why my code is not compatible with libstdc++.6.0.8? What all I have to check from my side to resolve this issue? -- View this message in context: http://www.nabble.com/JTC-System-call-exception-tp23918312p23918312.html Sent from the gcc - Help mailing list archive at Nabble.com.
