Hi Ben,

hmm...this is somewhat the same old story with the CXXFLAGS that is
used. you should set these at the target platform before running
configure (export CXXFLAGS=-DLINUX). A much better way is to use the Qt
defines for Linux to distinguish which OS you're on (as long as it's a
Qt project), otherwise you need to add the define to where your
configure check has the OS check and output it to config.h and include
that to your files.

Hope this helps,

We're not a company, we just produce better code at less costs.
