I did a clean, qmake and build from Qt Creator. The build fails with the following.

This builds from the command line using the same toolchain and mkspec.

I have no idea why qmake generated CXX as /root/work2/buildroot/output/host/usr/bin/arm-buildroot-linux-gnueabi-g++. Doesn't correspond to the configured toolchain.

Any help appreciated.

Also, I added the following to my .pro.

target.path = /nvdata
INSTALLS += target

I solved this by editing my qmake.conf. Pretty obvious what changes were needed. It would be interesting to know why I needed to provide a compiler path, if it is redefined in the qmake.conf.
