Hi, You know the @INC perl var, that has all the dirs that should be looked into for packages (for use, etc.)? well, the "#include <iostream.h>" line in your script (I am assuming there is such a line) is kind of like a "use CGI;" line would be in a perl script, and just as perl searches the @INC for CGI, the c compiler is searching for a header file named "iostream.h". As for why iostream.h could not be found, I do not know; what is in your include path?
