-EXPORTED_SYMBOL_FILE = $(PROJ_SRC_DIR)/../resources/lldb-framework-exports +#EXPORTED_SYMBOL_FILE = $(PROJ_SRC_DIR)/../resources/lldb-framework-exports That should fix both errors you're seeing. By the way, here's an updated version of my libInterpreter Makefile patch--new and improved, now with update to the test suite Makefile. It also avoids the need for printf(1) entirely--it just uses one echo(1) statement for the module list in the __init__.py files. Chip
