Those dynamic libraries are available.

/home/tuanhtrng/build/root-6.18/lib/libCling.so
/home/tuanhtrng/build/root-6.18/lib/libRIO.so

Does FindDynamicLibrary fail to find the files?

Also, the missing PCH is puzzling. The top-level CMakeLists.txt indicates etc/allDict.cxx.pch depends on headers, linkdefs, and cppflags which cmake is trying to build.

What do you guys think?

Do you have a more specific error message for this? Try with a verbose build, please.

The verbose ninja build.

There is no clear error message, so it’s difficult to guess what’s wrong. Most likely rootcling is crashing due to unexpected code paths since you are building on OpenBSD. Please provide more details about how you configured ROOT, what options you passed to CMake, for example, and try to use -DCMAKE_BUILD_TYPE=Debug so we can see what is causing rootcling to fail.
