I was watcing the tutorials from the above link,
they really are great, except one detail.

There are based on a .NET compiler, and I work with Dev-C++.

I do the FLUID video tutorial and write code into .cxx and .h
and import this files in new Dev-C++/Fltk project and compile.

Then I go to the console(so I could see the printf output)
start my program, and GUI part works perfecty, but there is no console output.

I try it again this time with -lshell32 option for linker, and still nothing.

What do I need to do to make my GUI app do output to console?

Ok here is the solution for Dev-C++.

Make a new console project.
Insert the fltk code, and the in project options -> parameters -> linker
add this:
-lfltk
-lole32 -loleaut32 -luuid -lcomctl32 -lwsock32
-lkernel32 -luser32 -lgdi32 -lm


What happened is that we fooled compiler that we are going to make a console application(so he would include console subsystem switch), and then we linked neccessary GUI libraries.
(note that there is no -lshell32 , it isn't necessary ???)

If the program is then started from GUI it will open console in the background in which you can write with <iostream>
(This is great for debugging)
If the program is started from console it will output to the console that started it.

I thik something similar could be done with .NET
I dont have a .NET but if someone has, don't hesitate to post a solution here.

See my reply in the Hide Console thread.

I replied before reading this thread so didn't know you were using dev C, looks like you figured it out, in any case.
