C++ system() not working!!?!? (Cygwin bash shell?)

Like I said, if you only need the compiler then get rid of Cygwin and install MingW. MingW does only contain programming-related tools!

Does it use the GNU g++ compiler or something different?

MingW is a port of the GNU Compiler Collection (commonly known as GCC). It include stuff like GCC, G++, GDB, LD, etc. I already mentioned all this earlier in the thread.

Well, you mentioned it was a "port of the GNU compiler collection". What does that mean?

Not that I really need to know, probably, but whatever...

EDIT:
This is something I found after some googling (I didn't understand it before you guys explained to me what Cygwin actually was....):
"The "-mno-cygwin" flag to gcc makes gcc link against standard Microsoft DLLs instead of Cygwin.
This is desirable for native Windows programs that don't need a UNIX emulation layer."

It worked for me (adding -mno-cygwin (no space between) to the linker cmd line options), what do you think?

Here's a link -mno-cygwin -- Building Mingw executables using Cygwin

EDIT: Sorry, didn't see third page. Apologies for restating what has already been said.

I think it's like some sort of shell or something that kind of runs on top of your operating system, sort of like a VM...? It's redirecting your system() calls to an intepreter other than cmd.exe, so that's why you need to call it explicitly.

That's my theory, anyway.

The GNU Compiler Collection is a set of programming-tools. I think we've got this thing right. It was originally made for Unix-system and that it is "ported" to Windows (through MingW, and too some degree, also Cygwin) means that the executables has been rewritten to work on Windows.

I still think that you should get rid off Cygwin, and use MingW instead. Then you don't have to play around with flags, like -mno-cygwin. Using MingW it will just work right away.

Yeah, I'll check that out. It shouldn't be too hard to make it work with NetBeans.

Thx for your help, guys!
