I' have been trying to install a real time kernel for my ubuntu 20.04, but after 2 days reading othe user issues and following guides, I always end in the same error when compiling the kernell. I would hihgly appreciate some help please, cause I'm very frustrated so far.
I have followed this guide, which is the guide for the robot I'm working on now:
https://open-dynamic-robot-initiative.github.io/robot_interfaces/doc/real_time.html
And this other guide from a user who was able to install it.
Install RT kernell in 20.04 LTS
Starting from a clean install of 20.04, first I have update the kernel to the same version of the real time(for example, 6.3.3). Then I have followed every step of those guides but I wasn't able to install it, my terminal shows this if I use make -j8 deb-pkg:
error: creating source package requires git repository make1: ***
[scripts/Makefile.package:40: check-git] Error 1 make1: *** Waiting
for unfinished jobs.... warning: Not a git repository. Use --no-index
to compare two paths outside a working tree usage: git diff --no-index
[]
and this if I use make -j8 bindeb-pkg:
make[4]: *** [Makefile:2025: .] Error 2 make[3]: *** [Makefile:357:
__build_one_by_one] Error 2 make2: *** [debian/rules:8: build-arch] Error 2 dpkg-buildpackage: error: debian/rules binary subprocess
returned exit status 2 make1: *** [scripts/Makefile.package:114:
bindeb-pkg] Error 2 make: *** [Makefile:1656: bindeb-pkg] Error 2
what I'm doing wrong? I configured the .config files as guide says but is not working
