Thank you, There is one more "link" problem (for an intrinsic function) : libitm.so: undefined reference to `__sync_add_and_fetch_8'
I found on the Net that there was a bug related to this on GCC 4.2, the solution was to specify the architecture (-march=i686) at compile time, but this doesn't solve the problem in my case, Is there any special flag that should be used when configuring GCC_TM ? -- Riyadh
