I'm trying to recompile my kernel. However, there was a gcc update since the installation of the sources/previous compile. Now the build process aborts:

Code:
make[4]: *** No rule to make target '/usr/lib/gcc/x86_64-pc-linux-gnu/7.3.0/include/stddef.h', needed by '/usr/src/linux-4.19.23-gentoo/tools/objtool/fixdep.o'.  Stop.                           
make[3]: *** [Makefile:43: /usr/src/linux-4.19.23-gentoo/tools/objtool/fixdep-in.o] Error 2
make[2]: *** [/usr/src/linux-4.19.23-gentoo/tools/build/Makefile.include:4: fixdep] Error 2
make[1]: *** [Makefile:63: objtool] Error 2
make: *** [Makefile:1647: tools/objtool] Error 2


I guess I need to update some configuration file. Can anyone tell me what to do? (I did the gcc-config change.)

do a
Code:
make clean
at first to remove all previous generated object files by the older gcc.
