<![CDATA[Qt giving the ld error]]>Hi ,

Based on the url http://wiki.wandboard.org/index.php/Building_Qt5_using_yocto_on_Wandboard

bitbake core-image-minimal and bitbake meta-toolchain-qt5

Both gave me success.

But after setting the qt creator and running the example clocks code its giving me the ld errors as follows

09:41:15: Running steps for project clocks...

09:41:15: Configuration unchanged, skipping qmake step.

09:41:15: Starting: "/usr/bin/make"

Error while building/deploying project clocks (kit: wandboard)

When executing step 'Make'

09:41:15: Elapsed time: 00:00.

I've assuared that the set up in the Configure Qt creators OK , but its still giving the error.

can you suggest me for that.

2)Th qt version http://picpaste.com/DSC_0028-Q8tV8259.jpg

3.qt mk specs here http://picpaste.com/DSC_0030-QXGHGWTh.jpg

I probabily guess the qt mk specs ...caan you specify what exactly to feed there?

The Linker tries to find the pthread-Libs in "/lib" but you are using a arm envirement, so try to find the libs for arm in your toolchane and add
@LIBS += -L/where_your_toolchane_libs_are -lpthread....@
in your .pro file.
