构建llgo + llvm时失败

Question

I was trying to build the llvm project from the sources. I'm interested in using (instrumenting) the go frontend. I followed steps from llgo repo. It fails when executing

make install

at 91%.

Alternatively, I followed building clang 8, llvm 8 on ubuntu 18.04. I managed to build clang+llvm. I tried to build llgo but failed terribly. What am I missing?

I'm using Ubuntu 18.04.2 LTS.

You seem to lack RAM for linking. Try running make without -j argument, switching CMAKE_BUILD_TYPE to Release and using gold or lld instead of BFD ld.
