ROOT Version: 6.34.08
Platform: Android Termux Arm 32-bit
Compiler: clang-9
Dear ROOT people, I would like to ask for some help compiling ROOT for arm/termux.
LLVM builds fine, but ROOT itself has issues.
I am compiling it like this:
-DCMAKE_CXX_COMPILER_LAUNCHER=ccache
-Dxrootd=OFF
-Dbuiltin_xrootd=OFF
-Dqt=OFF
I managed to compile it until 52%, compilation log not attached, because the forum will not let me either upload anything or post a link to an external upload server:
