qt4 sdk problem on rocko

qt4 sdk problem on rocko

[Belisko Marek]

Hi,

I'm porting our layers to latest rocko release. I build SDK to be able
to crosscompile our cmake based application which is using qt4. To
have qt4-tool in sdk I've added:
TOOLCHAIN_HOST_TASK_append = " nativesdk-qt4-tools"

Then in app CMakelists.txt I've use include(FindQt4) but it's barking
with following:
CMake Warning at
/opt/poky/2.4/sysroots/x86_64-pokysdk-linux/usr/share/cmake-3.8/Modules/FindQt4.cmake:618
(message):
  /opt/poky/2.4/sysroots/x86_64-pokysdk-linux/usr/bin/qmake reported
  QT_INSTALL_LIBS as "/opt/poky/2.4/sysroots/x86_64-pokysdk-linux/usr/lib"
  but QtCore could not be found there.  Qt is NOT installed correctly for the
  target build environment.
Call Stack (most recent call first):
  CMakeLists.txt:85 (include)

I did small check and seems that FindQt4 is using some mechanism to
find qmake and then based on qmake --query use variables. Problem is
that qmake -query report this:

/opt/poky/2.4/sysroots/x86_64-pokysdk-linux/usr/bin$ ./qmake -query
QT_INSTALL_PREFIX:/opt/poky/2.4/sysroots/x86_64-pokysdk-linux/usr

QMAKE_MKSPECS:/opt/poky/2.4/sysroots/x86_64-pokysdk-linux/usr/mkspecs
QMAKE_VERSION:2.01a
QT_VERSION:4.8.7

which is problem because I don't want to link + use included for x86
qt4 but for cross compiled.

Any ideas what to check? Thanks a lot.

BR,
