Subject: [PATCH] kconfig: abort configuration on unset symbol
|
|
|
|
When a target configuration has unset Kconfig symbols, the build will
|
|
fail when OpenWrt is compiled with V=s and stdin is connected to a tty.
|
|
|
|
In case OpenWrt is compiled without either of these preconditions, the
|
|
build will succeed with the symbols in question being unset.
|
|
|
|
Modify the kernel configuration in a way it fails on unset symbols
|
|
regardless of the aforementioned preconditions.
