Thanks for the bug report. Could you please post the full output of CMake run on a clean repository and output of make VERBOSE=1?

Thanks for the build logs. Looks like CMake cannot find pthreads:

-- Looking for include file pthread.h
-- Looking for include file pthread.h - not found
-- Could NOT find Threads (missing:  Threads_FOUND)

Do you have pthreads installed?

I think so: if I compile a .cpp file with #include "pthread.h", it compiles, with no additional include directories for clang++.

By the way, why does CMake generate a Makefile if some requirements are missing? Since CMake didn't fail, I thought that that was an optional requirement.

Good point. I've adjusted the CMake config so that the project compiles even if pthreads are missing: 7859f81.

But it is strange that CMake cannot find pthread.h. Where is this file located on your system?

/usr/include/pthread.h. It looks like a standard path..

Hence, is pthread.h needed or not? Does CppFormat builds two versions of the library: single-threaded and multi-threaded? Sorry, but I am new in developing C++ on GNU/Linux.

However, now CMake finds the header, but not a required function:

-- Looking for include file pthread.h
-- Looking for include file pthread.h - found
-- Looking for pthread_create
-- Looking for pthread_create - not found
-- Looking for pthread_create in pthreads
-- Looking for pthread_create in pthreads - not found

pthread.h is not needed any more. There is only one version of the library and it doesn't require pthreads, the latter is only optionally used by Google Test. So you can ignore pthreads-related messages from CMake.

Now the build works and the tests are successful.

Thanks for your assistance.
