| |
Just tried to run 'make menuconfig' on v4.18-10568-g08b5fa819970 and found a bad surprise:
'make *config' requires 'pkg-config'. Please install it. make[1]: *** [scripts/kconfig/Makefile:219: scripts/kconfig/.mconf-cfg] Error 1
This is clearly a regression - I have libncurses devele pakcage installed in the default system location (as do 99%+ on actuall develeopers proobably) and in this case, pkg-config is useless. pkg-config is needed only when libraries and headers are installed in non-default locations but it is bad to require installation of pkg-config on all the machines where make menuconfig would be possibly run (for example, I have a aboult 100 machine kernel testbed with self-hosted kernel compilation and machine-specific kernel configurations that ocassionally need tweaking).
I notice 4.18 complained it can not find pkg-config but still worked. This is clearly better than now.
If we want to support developers with libraries in non-default locations, why not - but the common case of system include path should work without any trouble or warnings. For exaple, test if compilation against ncurses works, and if not retry it with pkg-config (and error out if it does not give working result).
