example of broken python build
Ok. My guess is that: *) You built once without WCHAR support in the toolchain (BR2_USE_WCHAR not enabled) *) You went back in menuconfig, enabled Python. But to do this, you enabled WCHAR support in the toolchain. And then, instead of doing a complete "make clean all" cycle that ensures the toolchain gets rebuilt, you just did "make". So it tried to build Python without rebuilding the toolchain, leading to your error. I'm pretty sure that the problem will go away if you do a "make clean all" cycle. I tested your configuration here and it built just fine. HI, Yep you are indeed a fortune teller........ Did "make clean all" and it did solve the problem, just it extends the build time every time. |
