Set LD_LIBRARY_PATH on Linux for NIF shared library resolution#217
Merged
Conversation
When using custom_erts with a glibc-linked ERTS (e.g. from builds.hex.pm), NIF .so files may depend on system shared libraries like libgcc_s.so.1. The BEAM process doesn't search standard system library paths by default, causing dlopen to fail. Add common system library paths to LD_LIBRARY_PATH so NIF shared objects can find their dependencies.

This all makes sense to me! I'll kick off CI tests, and merge after they pass |
