            Bug ID: 44099
           Summary: can't link a program with both llvm and libclang-cpp
           Product: Packaging
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: binary tarballs
          Assignee: unassignedbugs at nondot.org
          Reporter: mikulas at artax.karlin.mff.cuni.cz
                CC: llvm-bugs at lists.llvm.org

The binary tarball contains static libraries for LLVM and dynamic libraries for
clang. They can't be linked together.

How to reproduce:
1. download the tarball
http://releases.llvm.org/9.0.0/clang+llvm-9.0.0-x86_64-linux-gnu-ubuntu-16.04.tar.xz

2. unpack it to /opt/clang+llvm-9.0.0-x86_64-linux-gnu-ubuntu-16.04

3. create a "test.cpp" file with this content:
#include "llvm/Support/TargetSelect.h"
int main(void)
{
        llvm::InitializeNativeTarget();
        return 0;
}

4. run g++ test.cpp
`/opt/clang+llvm-9.0.0-x86_64-linux-gnu-ubuntu-16.04/bin/llvm-config --cppflags
--cflags --cxxflags --ldflags --libs --system-libs` -lclang-cpp

5. run ./a.out

you get this error:

: CommandLine Error: Option 'x86-machine-combiner' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options

The binary tarballs should contain the LLVM.so dynamic library to avoid this
error.
