Why fortran produces large files (.exe)?

[Mietze]

Hello!

I´m learning fortran since a few weeks and now i compared the size of a fortran and a 'C' executable ( a simple Hello World program ) and i was shocked: fortran produces about 220-330KB,
'C' about 20KB.
220...330KB for a very simple program??

I used the old Compaq Visual Fortran Compiler 6.1 (220KB) and
the g95 (330KB)

Why Fortran do this ??

It depends on your code generation mode. In CVF, there are 3 main modes (under Fortran/library)

o single threaded
o multi-threaded
o multi-threaded DLL

The first two put all the code from the fortran run-time library in the executable. The last one picks the run-time library when the program is executed. It means that you have to supply the runtime-library as part of the executable and loading is a lot slower but the size is 14K as opposed to 320K. If you build in release mode, it is even smaller (5K).
