You've not installed your compiler properly. Particularly, the path to the files it needs.
so, should I re-install my compile?
don't worked =((
for some unknown reasons, re-install the IDE make it work well ;O
Seems to be what Moschops said 2 days ago...
for Code::Block user, because of several times having same problem today, and after searched the net, the problem lies behind the "Compile File" and "Link File" that I set on properties(should not have set up any random setting that I don't know =..=)
makesure both option UN-check (only check "Compile File" if you want to make the header file as precompile file)
that's all. ;D
