Installation fails on macOS 11.0.1 Big Sur in tbb module

Hi all,

I am trying to test install ROOT 6.22.04 on macOS 11.0.1 Big Sur, but it fails when trying to compile TBB:

CMake Error at /Users/a/root_v6.22.04/root_v6.22.04-build/TBB-prefix/src/TBB-stamp/TBB-build-Release.cmake:49 (message):
  Command failed: 2

   'make' 'compiler=clang' 'cpp0x=1' 'CXXFLAGS= -mno-rtm -isysroot /Applications/' 'CPLUS=/Applications/' 'CONLY=/Applications/'

make[2]: *** [TBB-prefix/src/TBB-stamp/TBB-build] Error 1
make[1]: *** [CMakeFiles/TBB.dir/all] Error 2

With TBB-build-out.log:

Created ./build/macos_intel64_clang_cc12.0.0_os11.0.1_release and ..._debug directories

And TBB-build-err.log:

build/ "Warning: deprecated cpp0x=1 is used, stdver must be used instead. Building in stdver=c++0x mode."
../../build/Makefile.tbb:28: CONFIG: cfg=debug arch=intel64 compiler=clang target=macos runtime=cc12.0.0_os11.0.1

Any help is appreciated.

Compiler: Default from Xcode 12.2

Hi Andreas,

ROOT is not yet released on macOS 11 but we are building the head of development. Could you try with the latest master branch from git?


Or you can curl -O or curl -O to just grab a nightly binary!
