Hi, I am installing root for the first time, have downloaded all the prerequisite. Then while using make -j4 I’m getting following message:

[ 65%] Building CXX object interpreter/llvm/src/tools/clang/lib/CodeGen/CMakeFiles/obj.clangCodeGen.dir/BackendUtil.cpp.o
{standard input}: Assembler messages:
{standard input}:2903: Error: unknown pseudo-op: `.wea'
c++: fatal error: Killed signal terminated program cc1plus
compilation terminated.

please guide me regarding solution of this problem as I don’t know why it’s arising.

ROOT Version: 6.28.04
Platform: Ubuntu 22.04.2

Welcome to the ROOT forum.

I am not sure what the problem could be. Can you give more details on the procedure you used? As it seems an error in the interpreter may be @vvassilev and @Axel can help.

Hi @roy11 !

First of all: why do you try to build ROOT? You can install ROOT through conda, through your package manager, or if none of that works by download a pre-built binary. Compiling yourself should be the last option :slight_smile: (You don’t compile Python yourself either :wink: )

Now, if compiling is really what you need to do then: the error message you get indicates a mismatch between your compiler and your binutils package, which usually means “your system is broken” or your compiler isn’t installed correctly.

Cheers, Axel

Thank you for helping, I was following the instruction I found regarding installation of root in Windows with WSL, I was not aware of the fact that it can be installed via conda. I hope now I’ll be able to get it done. Thank you.
