 |
|
I have gcc 8.2 installed:
# gcc-config --list-profiles
[1] x86_64-pc-linux-gnu-8.2.0 *
gcc-7.3 was removed after depclean (month or so ago). I performed few system update with current gcc-8.2, but when I trying to compile kernel (I want to add wireless module) I getting this error:
| 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 |
Looks like kernel requiers old gcc-7.3
How do I fix this?

You tried with a make clean in kernel?

| You built that kernel with gcc-7.3.0, so some objects now have a Make dependency on the headers from that version. As fedeliallalinea said, clean out generated files and start fresh. Fortunately, your kernel is also out of date, so you can take this opportunity to upgrade to a newer kernel release. |

If you're going to do a distclean then save your .config file (unless you want to start the configuration from scratch)

Indeed I forgot to mention how useful the config option is to use something like | Code: | | zcat /proc/config.gz > .config |
