Here is the information about my system and the compiler I use:

Linux version 4.9.0-5-amd64 (debian-kernel@lists.debian.org) (gcc version 
6.3.0 20170516 (Debian 6.3.0-1
8) ) #1 SMP Debian 4.9.65-3+deb9u2 (2018-01-04)

clang version 5.0.1-svn325091-1~exp1 (branches/release_50)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

I have problem with building llvm-6.0.0 with libcxx. I downloaded all of them from llvm download page and put the source code like there:

llvm-6.0
 build
 llvm-6.0.0
 ...(other stuff)
 tools
 clang
 projects
 libcxx 
 libcxxabi

And here is the command I used:

#!/bin/bash
#References: https://libcxx.llvm.org/docs/BuildingLibcxx.html
cd build
#The option for llvm starts from line 5, for libcxx starts from line 15

I tried to fix this problem by:

1. Use cmake --build . --target clean to remove the built files and run cmake --build . again.




2. Follow the instruction given above, change directory into lib, and run ranlib libLLVMSupport.a.

But none of these worked: I ran cmake --build . again, and they gave:

make: *** [all] Error 2

I checked the timestamp of lib/libLLVMSupport.a in method 2, and found it was not changed, means it was not regenerated by cmake --build ..

How to fix this?

Why don't you leave the archives as separate files? and then link the application to all the required archive(s).

I have finally found out what really caused this error.

The cmake was using gnu golden linker, and the archieve libLLVMSupport.a was composed of LLVM IR code, no wonder it went wrong.

After I switched to using ld.lld-5.0, all errors were gone.
