Bug ID: 45838
Summary: duplicate symbol error when using llvm-ar and
llvm-ranlib to build bash 5
Product: tools
Version: trunk
Hardware: PC
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: llvm-ar
Assignee: unassignedbugs at nondot.org
Reporter: zapster at zapster.cc
CC: llvm-bugs at lists.llvm.org
Building bash 5 on MacOS using llvm-ar and llvm-ranlib fails with "duplicate
symbol" error.
To reproduce the error, get the bash 5 source code (e.g. from here
http://ftpmirror.gnu.org/bash/bash-5.0.tar.gz) and build it using llvm-ar
llvm-ranlib:
tar -xf bash-5.0.tar.gz
mkdir bash-5.0/_build
cd bash-5.0/_build
AR=/path/to/llvm_build/bin/llvm-ar RANLIB=/path/to/llvm_build/bin/llvm-ranlib
../configure
make -j
This will result in an error similar to the following:
gcc -L./builtins -L./lib/readline -L./lib/readline -L./lib/glob -L./lib/tilde
-L./lib/sh -Wl,-why_load -g -O2 -Wno-parentheses -Wno-format-security -o

I've tried this with various llvm version (9.0.0, 10.0.0 and master). Also,
when switching one of the tools (llvm-ar or llvm-ranlib) to the system tool the
error is gone. The compiler does not matter (tried gcc 8 and various clang
versions).
This file was originally filed against the GraalVM LLVM Runtime toolchain,
which uses the llvm binutils:
