I'm trying to build Linux Kernel ffor Ubuntu 20.04 with GCC 9.3.0.
There are instructions out there https://wiki.ubuntu.com/KernelTeam/GitKernelBuild
make -j $(getconf _NPROCESSORS_ONLN) deb-pkg LOCALVERSION=-custom
After long running compiling C source files process I got the error:
make[2]: *** [debian/rules:7: build-arch] Error 2
dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
make[1]: *** [scripts/Makefile.package:77: deb-pkg] Error 2
make: *** [Makefile:1559: deb-pkg] Error 2
What this error could be about?
