In Windows with cl.exe ,
warning format is d:\path\Hello.cpp:131:2: <...>
error format is d:\path\Hello.cpp(694) : <...>
Somehow, qt-creator parses and shows these errors but does not open the file when clicked: File not found.
I tried every toolchain creator 2.0 offers.
I'm using jam and had to manually redirect 2>&1 stdout to stderr console in order to see anything in the tab "build problems".
