Bug ID: 41214
Summary: Undefined reference when I link libc++
Product: libc++
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: All Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: praveenvellieng...@gmail.com

Hi,
When I compile this example
[https://reviews.llvm.org/diffusion/L/browse/llvm/trunk/examples/HowToUseJIT/HowToUseJIT.cpp
]from the trunk, the linking fails.
Command used to compile :
clang++ -stdlib=libc++ -fuse-ld=lld howto.cpp `llvm-config --cxxflags
--ldflags --libs`
the linker throws up
ld.lld: error: undefined symbol:
llvm::EngineBuilder::EngineBuilder(std::__1::unique_ptr<llvm::Module,
std::__1::default_delete<llvm::Module> >)
But when I link libstdc++ instead of libc++, error was gone.
Is this a known bug?
Is there any workaround for this?
My clang++ -v shows:
clang version 9.0.0,
Target: x86_64-unknown-linux-gnu.
