QtCreator and Ninja warning/error parsing

We have a custom build binary that launches ninja and we couldn't get QtCreator to parse the warnings from that output. Errors/warnings show up, they just weren't being parsed. I finally got QtCreator building with symbols and tracked it down to this in makestep.cpp:

 267     if (m_useNinja)
 268         AbstractProcessStep::stdError(line);
 269     else
 270         AbstractProcessStep::stdOutput(line);

Ninja is processing stderr and regular makefiles are processing stdout. So I added this to our custom shell script and it's working now:

Command: .../bin/mkvogl.sh
Arguments: --amd64 --debug 3>&1 1>&2 2>&3

I guess if you ever find QtCreator isn't parsing your output, try swapping stderr and stdout. :)

If anyone wants to get QtCreator building release with symbols on something vaguely resembling 64-bit Linux Mint 16, this is what I wound up doing:

apt-get install: libgl1-mesa-dev libxml2-dev libglib2.0-dev libxslt1-dev libglib2.0-dev libgstreamer-plugins-base0.10-dev libgstreamer0.10-dev

If there is a better way of achieving this, please let me know - I don't know much about qmake and couldn't find anything...
