I am trying to install ROOT v6.22 from source on my Mac - I can get it wokring without ROOT7 but I want to use some of the development features so I tried this:
it seems OK (no error) then when I attempt to make I am seeing this error:

Any ideas what the issue might be - I have the latest gcc and clang installed so it should have access to c++17
Hm, std::make_unique should be part of the memory header, which is included. Could you try if it helps to #include <ROOT/RMakeUnique.hxx> and, if that doesn’t help, to replace in RError.hxx line 142

How did you guys get 10.0.1 (@jblomer) and 11.0.0 (@smd) on your 10.14.6? I have the same osx version and clang 10.0.0 and can’t find a way to update it
Alja has osx-15 and clang 11.0.3 there.
Is it possible some headers from osx-14 interfere with clang-11?
OK let’s see. @smd could you upload the file CMakeCache.txt? What does cmake --version say?
It’s strange that CMake sets -std=c++1z, I would have expected -std=c++17.
std::make_unique exists since C++14, so indeed, rootcling isn’t built with the proper C++ standard. Is this on an existing build directory? Can you do make -j4 clean; rm CMakeCache.txt; cmake -DCMAKE_INSTALL_PREFIX=../root_install/ ../root_src/ -DCMAKE_CXX_STANDARD=17 -Dhttp=ON -Droot7=ON; make -j 12 - does that help?
