Hi I'm trying ot migrate C++ code from AIX (XL C ) to Red Hat 7.3. I have insatlled GCC 4.0.1 on Red Hat. I am getting a whole bunch of compilation problems on using gcc 4.0.1 which will be quite difficult to include in this mail. Can someone guide me as to how to go about removing the problems encountered while doing such a code migration? Is there some documentation available where I can get the differences between these two compilers ? One of the errors I encountered was : <filename>.cc:64:23: error: strstream.h: No such file or directory This error is not generated when the compilation is done by GCC 2.9.6.
