New MinGW gcc doesn't do anything

Question

I'm trying to compile a simple helloworld program with MinGW on Windows and nothing happens. No output, no executable, nothing. I've just installed the latest MinGW with their mingw-get-inst-20120421.exe installer. When I use an older version of MinGW that came with Code::Blocks, I am able to compile the program. I'm out of ideas and my googling has been in vain. C:\MinGW\bin is on my path and I'm using MSYS.

Command line parameters in MSYS:

gcc helloworld.c -o helloworld

Answer 1

Execute the console from the Start menu, Start->MingW->MinGW Shell or from filesystem:

C:\MinGW\msys\1.0\msys.bat

Execute gcc in this shell.

Otherwise you will have to add the minGW/bin directory to your PATH environment variable.
