Thanks Michael.
Now I understand a little bit more. I installed it into PTXCONF_SYSROOT_TARGET because CROSS_PYTHON has the default site-packages search path there. I know this was wrong because it is a host tool which should installed into PTXCONF_SYSROOT_HOST. I always search a way to change the default site-packages search path and now I found it! [1] Your solution to install it into HOST_CYTHON_PKGDIR will install Cython into PTXCONF_SYSROOT_HOST which is correct, but then it doesn't work out of the box, because CROSS_PYTHON doesn't search in PTXCONF_SYSROOT_HOST. With solution of [1] I can change the site-packages search path with: "$(CROSS_ENV) PYTHONUSERBASE=$(PTXCONF_SYSROOT_HOST) $(CROSS_PYTHON)" and then it works with a installed Cython in PTXCONF_SYSROOT_HOST. Please let me know if this is okay for you, maybe we can put this into the default $(CROSS_PYTHON) path. It seems Cython is some special thing, we need it only at compiletime and it have some cross compiled things in there. I don't know what happens if we set PYTHONUSERBASE and python uses still his default site-packages path or not. - Alex [1] http://pymotw.com/2/site/ -- ptxdist mailing list [email protected]
