execution pb C++

Hello,

I have a very strange pb.
I develop a software with C++ (Linux).
When I execute my program, the terminal says:
02376: symbol=strlen; lookup in file=./client
02376: symbol=strlen; lookup in file=/usr/lib/libstdc++.so.5
.....

I would like to know if there are errors or if it depends on my compilation options ??

Have you ever seen this ???
Thanks

NB: Sorry for my english !!!!!!

You may want to try asking your question in another forum, possibly the C++ (Non Visual C++ Issues) forum, as this forum is for Visual C++ and thus is geared towards the Windows platform.
