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 switching back to a branch.

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

git switch -c

Or undo this operation with:

git switch -

Turn off this advice by setting config variable advice.detachedHead to false

You will have to resolve the conflicts manually

Does anybody know, why I'm having this dependancy problem while trying to compile library from a source?

This is probably an issue with the version of CMake. CMake ~< v1.20~ < v3.20 seems to have problems with its FetchContent functionality and how hiredis config is setup. The advice is to upgrade CMake or install hiredis manually, and we will add some block/warning text to our CMakeLists.txt

I've got Ubuntu 20.04.5 with latest cmake installed

dpkg -l | grep cmake

ii cmake 3.16.3-1ubuntu1.20.04.1 amd64 cross-platform, open-source make system ii cmake-data 3.16.3-1ubuntu1.20.04.1 all CMake data files (modules, templates and documentation)

Hiredis is also installed manually

dpkg -l | grep hiredis

ii libhiredis-dev:amd64 0.14.0-6 amd64 minimalistic C client library for Redis (development files) ii libhiredis0.14:amd64 0.14.0-6 amd64 minimalistic C client library for Redis But hiredis-cluster does fetch it's source code automatically and tries to compile it.

[bjosv]

Sorry, I gave the wrong version. A fix for this came into CMake v3.20.

[bjosv]

You can skip the automatically download with cmake -DDOWNLOAD_HIREDIS=OFF .. but then a recent hiredis needs to be found.

Thank you! It works now! One more question: How to compile library without debug information, what should I put instead: -DCMAKE_BUILD_TYPE=RelWithDebInfo ?

[y291arh]

The answer is: -DCMAKE_BUILD_TYPE=Release Thanks!
