Hello, I reported a difficulty I was experiencing in compiling with gcc-3.3.3. I just realised that if I omit <iostream> header file, and instead used <stdio.h>, gcc-3.3.3 compiles! It also does not seem to flag <ostream> or <fstream>. Perhaps this has been treated elsewhere, but I haven't succeeded in retrieving such a discussion from the archives. I would appreciate any information on how to overcome this, as I would have to rework a whole ton of code to remove all references to 'std::cout' -which gcc-still flags as undefined. I could still ignore gcc and use g++, but my code calls in BLAs libraries and I suppose gcc is needed for the language transfer from C++ to Fortran. Thanks a lot! -Tobe. __________________________________ Do you Yahoo!? Yahoo! Small Business - Try our new resources site! http://smallbusiness.yahoo.com/resources/
