c Makefile expects ./bin/ to exist but doesn't create it if missing. And it's not in the repo itself.

Try using the root to make. eg: sudo make

parkerlreed commented 3 years ago

root doesn't make any difference here. The ./bin directory is defined but never checked to see if it exists/created. https://github.com/waveshare/e-Paper/blob/master/RaspberryPi_JetsonNano/c/Makefile#L6

SSYYL commented 3 years ago

We have not considered the problem, Because normally this directory exists. you can create the ./bin manually.
