This has found the header files, and in fact compiled. All a header file
does is _declare_ stuff, not define it. To define it you need to wither
write the routine in your code or include the library that has it. In your
case, the latter.

Put simply: you need to link a library with iostreams in it.

Try this:
gcc -o output.exe input.cc -liostream
                            ^^^^^^^^^
This does it all in one step. Or you could try

gcc -c file1.cc
gcc -c file2.cc
gcc -o output.exe file1.o file2.o -liostream

Anyway, it is the -liostream that is missing.

Regards,
Brett
