Unable to install LLVM

Beginners
#1

I’m trying to install LLVM-7.0.1 on BLFS 8.4 using commands (below) after extracting it in /sources/BLFS.

mkdir -v build &&
cd build &&

CC=gcc CXX=g++
cmake -DCMAKE_INSTALL_PREFIX=/usr
-DLLVM_ENABLE_FFI=ON
-DCMAKE_BUILD_TYPE=Release
-DLLVM_BUILD_LLVM_DYLIB=ON
-DLLVM_LINK_LLVM_DYLIB=ON
-DLLVM_TARGETS_TO_BUILD=“host;AMDGPU;BPF”
-DLLVM_BUILD_TESTS=ON
-Wno-dev -G Ninja … &&
ninja

I had run this command in /sources/BLFS/llvm-7.0.1-src

The Error is " internal compiler error: segmentation fault "
It fails at various .cpp files.

#2

This seems to be your host GCC crashing? Which version of gcc are you using?
Can you post maybe more context (a few lines of the log) around the error?

#3

I am using gcc 8.2.0
I think that the problem is due to bad ram and I have put my laptop on repair.
Therefore I cannot show any log files today but the problem mostly occurred in “utils/TableGen/_____ .cpp”
For example DAGISelMatcherEmitter.cpp or GlobalISelEmitter.cpp

#4

Thanks @mehdi_amini.
Finally it did compile.
As I thought the culprit was the faulty ram. I just removed a module which I guessed could be the faulty one and it did work!
