missing warning messages

(1/3) > >>

larsjo:
I take this program, test.c:
int main(){ }
and compile with the command line:
$/cygdrive/c/Program\ Files/CodeBlocks/MinGW/bin/mingw32-gcc.exe   -Wall test.c
Then the following warning message shows:
test.c:1: warning: control reaches end of non-void function

This is all very well. However, when I compile the same code in Code::Blocks (v.10.05) it says "0 errors, 0 warnings". I do think this deserves a warning message, and it should show since CodeBlocks uses the same compiler as I did at the command line call.

I have checked the  -Wall  square at three locations:
The first two by going in to the menu bar: Project > Build options...
To the left I mark "Debug" and check the -Wall-square
and then I, to the left, mark the "root" and check the -Wall-square

Finally I once more go to the menu bar: Settings > Compiler and debugger...
and again I check the -Wall-square.

What more is necessary to make the warning show up?

Some warning messages show up anyway, but somehow not all those that should.

oBFusCATed:
Why don't you try some of the two newer versions of codeblocks (12.05 or 13.12)?

larsjo:
This is the version installed at my university.

oBFusCATed:
What is -WAll-square?

BTW: Tell them to update, it is almost free:)

frithjofh:
i think he means the tick-mark, where up enable/disable this option... its kind of square... the wxCheckBox
