[Interest] qt giving the ld error

[Nilesh Kokane]

Hi Christiab,

Thanks for your valuable reply first of all.

make sure that arm-linux-gnueabi-g++ refers to /opt/poky/1.6.1/... and
not /usr/lib/gcc-cross/..., from a console you can check for this with
this command:
$ which arm-linux-gnueabi-g++

I gave me the following.
/usr/bin/arm-linux-gnueabi-g++


Or set the full path to your cross-gcc in QtCreator "Build&run" config.

I just checked by giving the full path in the qt mkspec as* but its showing
the warning sign

(*/opt/poky/1.6.1/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/lib/qt5/mkspecs/linux-arm-gnueabi-g++)


can you please suggest

Thanks
Nilesh kokane
