[Qt-creator] Cross-compiling for ARM with qt creator

[eike.ziller at nokia.com]

Hi,
I'd expect your cross-toolchain's linker /usr/arm-linux-gnueabi/bin/ld to find libraries in /usr/arm-linux-gnueabi/lib, so no idea.

Anyhow, to me that sounds like a more general "cross compile with Qt" question unrelated to Qt Creator, because I suppose doing
qmake -r -spec qws/linux-arm-g++ && make
for your project on the console would give the same result?
In that case I'd suggest to ask again on interest at qt-project.org where more people with knowledge about that topic might lurk around.

Br, Eike
