Yocto: cross-compile problem with QtCreator

[seypa]

Hello,

i use the meta-toolchain-qt5 from the Yocto Project to create a cross-compile Environment for an ARM Board (am335x) on an Ubuntu x86_64 host.
I can already compile a Project within the console with:

source /opt/qt5devtools/environment-setup-cortexa8hf-vfp-neon-linux-gnueabi
qmake
make 

But it fails within the QtCreator. I inserted already the "source" in the first line of the qtcreator.sh
But everytime i want to compile the Project I get the following error:

/usr/bin/make -f Makefile.Release
make[1]: Entering directory '/home/in-tech/server_sw'

This already happens with a simple Hello World program. Seems like some Library Path is missing?
Would be great if anybody could help.
Thanks

Hi and welcome to devnet,

Did you check where that header might be in your cross-compiler setup ?

Did you find a solution for this problem? I currently have the same issue.
