I've got a problem creating a yocto (thud) recipe for the rpi_ws281x python module. The machine itself is a raspberrypi3.
While building the recipe I get the following error:
NOTE: Executing SetScene Tasks
NOTE: Executing RunQueue Tasks

The recipe itself looks like this:

#DEPENDS += "python-setuptools-native swig-native python-scons-native"
DEPENDS += "swig-native python-scons"
RDEPENDS_${PN} = "python"
S = "${WORKDIR}/git"
inherit scons setuptools
do_compile_prepend() {
cd ${S}/
scons
cd ${S}/python/
${PYTHON} setup.py install
}
What I'm wondering about is that scons creates some binary code for linux-x86_64. Is there any possibility that I can convice scons to use the exported Environment of Yocto?
Thanks in advance,

Now it works. I fixed the SContruct, created a patch and used the following recipe.
