You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

git checkout -b

Generating B2 configuration in project-config.jam for clang...

Bootstrapping is done. To build, run:

./b2

To generate header files, run:

./b2 headers

The configuration generated uses clang to build by default. If that is
unintended either use the --with-toolset option or adjust configuration, by
editing 'project-config.jam'.

Further information:

• Command line help:
  ./b2 --help

Util/BuildTools/Linux.mk:142: recipe for target 'setup' failed
make: *** [setup] Error 1
The above is what I have been getting regardless of what I have tried, I have clang-10, 8 and 11 installed and on the added to cxx and cc path as well installed g++-10, 8 and 11, but there is a fundamental problem: clang-11 is required to build b2, but carla requires clang-10 as a user specified requirement, which means the build checks for two different versions of the same software and would fail if one is not set. This is my basic understanding of this. Has anyone come across this problem or have a solution that would help?

export UE4_ROOT=~/UnrealEngine_4.26

set this to the folder location of your cloned unreal engine, do not just copy paste and run
there are no error codes when you do this, the error comes after running make.
after this you may run into a bad head error, try:
the error occurred because of #CARLA_VERSION=$(get_git_repository_version) in line 878 of Setup.sh .
change it to your Carla version and it would be work.
I've changed it to CARLA_VERSION="0.9.15"
