I suppose I should qualify my statement a little: _C++_ code is not compatible between older versions of GCC and newer ones. C code should still work fine. However, it looks like you're working with C++ code, so it still applies...

I was not aware of the incompatibility between binaries produced with versions of gcc prior to 3.2 and newer versions. Knowing this makes it easier to deal with going forward.

Rather, the -V option is deprecated and is not supported in recent versions of GCC. If you are trying to link code built with the new compiler with libraries built with the old compiler, you're not going to have any luck. Newer versions of GCC are not compatible with binaries produced with versions of GCC prior to GCC 3.2.

I am now having a problem with code that compiled just fine under gcc 2.96 but now does not compile under gcc 3.2.2. I have tried the -V option but apparently the upgrade of Red Hat 9 screwed up the former system so that using the "-V 2.96" option complains that it cannot find the cc1plus file. The code compiles fine but I get tons of link errors that are all about "new" and "delete" operators. They are all in the form of: .....undefined reference to 'operator delete[](void*)' .....undefined reference to 'operator new(unsigned)' Do I have to specifically link with a special library just to get this code to link properly? Thanks for any help you can provide. I have looked through the man pages and the online documentation but came up clueless. -Andres ---------------------- Andres C. Gonzalez III Agora Labs, Inc.
