How to install LLVMgold.so for clang+llvm binary package?

Question

I would like to use llvm control flow integrity and I used the clang+llvm binary packaged version 7.0.1 shipped for Ubuntu 14.04. When I use clang++ with options '-fsanitize=cfi -flto -fvisibility=hidden' I get the following error:

/usr/bin/ld: /home/username/llvm-7.0.1/bin/../lib/LLVMgold.so: error loading plugin: /home/username/llvm-7.0.1/bin/../lib/LLVMgold.so: cannot open shared object file: No such file or directory

Any idea how can I fix that without compiling the source code with option that enables gold?

Answer 1

I received a similar error when linking with clang 13.0.0-2.

/usr/bin/ld: /usr/lib/llvm-13/bin/../lib/LLVMgold.so: error loading plugin: /usr/lib/llvm-13/bin/../lib/LLVMgold.so: cannot open shared object file: No such file or directory
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I ran apt search for llvmgold and found llvm-13-linker-tools recommended. Installing this made the issue go away.

sudo apt-get install llvm-13-linker-tools

I got clang simply via sudo apt-get install clang. Try looking for the llvm-7 equivalent.

I received a similar error warning when trying to compile Python from sources with --with-lto option on Ubuntu 14. The easiest thing to do was to just remove the --with-lto flag during configuration.
