Hi Thomas,

this seems to be a python2 <-> python3 problem:

$ grep -i "ge_python \|ge_python3=" .config
# BR2_PACKAGE_PYTHON is not set

host-python is compiled as

$ ls -la output/build/ | grep host-py
drwxr-xr-x 17 fli4l fli4l  4096 Mär 21 10:48 host-python3-3.4.2
drwxr-xr-x  9 fli4l fli4l  4096 Mär 21 10:48 host-python-mako-1.0.1

but mesa3d checks for python2 first which picks up /usr/bin/python on my

$ grep PYTHON2 output/build/mesa3d-10.5.1/config.log

due to "AC_CHECK_PROGS([PYTHON2], [python2 python])" in


MESA3D_CONF_ENV += ac_cv_prog_PYTHON2=$(HOST_DIR)/usr/bin/python

to mesa3d.mk forcing the usage of host-python3 does not help either:

checking if module mako in python is installed... Traceback (most recent
call last): 
  File "<stdin>", line 10, in <module>
TypeError: unorderable types: map() > map()
configure: error: mako 0.3.4 or later is required.
make: *** [/home/fli4l/br3/output/build/mesa3d-10.5.1/.stamp_configured]
Fehler 1 

Please note that mesa3d does not need the target version of python, only
host-python 2.x. 

Is it possible to compile host-python2 parallel to host-python3 or should
I add a "depends on !BR2_PACKAGE_PYTHON3" to mesa3d/Config.in? 

Regards, Bernd
