Debugging With Erlang
First, make sure you have the compile flag (+debug_info) set when compiling your source, then fire up the debugger:
My Erlang Makefile:
EBIN_DIR := ebin SRC_DIR := src EXAMPLES_DIR := examples INCLUDE_DIR := include ERLC := erlc ERLC_FLAGS := +debug_info +native -W -I $(INCLUDE_DIR) -o $(EBIN_DIR) all: @mkdir -p $(EBIN_DIR) $(ERLC) $(ERLC_FLAGS) $(SRC_DIR)/*.erl clean: @rm -rf $(EBIN_DIR)/* @rm -f erl_crash.dump
The debugger can be a bit weird in that it doesn’t always find your ebin directory (if you’re compiling to a separate ebin dir)… it took me a bit to figure out. Also on the Mac it seems to either crash or not launch timetimes.If you found this post helpful, please consider sharing to your network.
