llgo fails when' Performing build step for 'libgo'

[Moeketsi Raselimo]

I have tried build the llgo following this REAME.txt . The only differences are in the cmake command and make. I ran the following instead

cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DLLVM_BUILD_DOCS=OFF -DCMAKE_INSTALL_PREFIX=/usr/local/clang_8.0.0 ../llvm

and 

 

make-j 8

I'm using a machine with the following specs: Ubuntu-18.04.2 LTS with 16GiB RAM.  

GCC version: gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0 

Cmake version : 3.10.2

go version: go1.12.4 linux/amd64

I'm getting the following errors.

I'm having the same problem with f181dd99cf1c4e94f1e191b4ffb7357571af9039 of llvm-project (from GitHub). From the log, the actual error itself appears to be:

llgo: /home/felix/Downloads/llvm-project/llvm/lib/IR/Attributes.cpp:233: llvm::Type *llvm::Attribute::getValueAsType() const: Assertion `isTypeAttribute() && "Invalid attribute type to get the value as a type!"' failed.

When building in parallel, this identical error appears for each source file.
