| |
When you build targets that require the kernel configuration, dot-config is set to 1, then the top-level Makefile includes auto.conf. However, Make considers its inclusion is optional because the '-include' directive is used.
If a necessary configuration file is missing for the external module building, the following error message is displayed:
ERROR: Kernel configuration is invalid. include/generated/autoconf.h or include/config/auto.conf are missing. Run 'make oldconfig && make prepare' on kernel src to fix it.
However, Make still continues building; /bin/false let the creation of 'include/config/auto.config' fail, but Make can ignore the error since it is included by the '-include' directive.
Use the 'include' directive instead. This allows the /bin/false to correctly terminate the whole build process.
