meck fails while running 'meck:expect'

README.md

Here's a test project with 2 files that shows the problem.

You need 2 modules

• in the first module you should have a eunit test
• in the second module you should meck any function from the first module

When you run eunit, the meck fails at 'meck:expect' with 'undefined' exception.

How to reproduce:

./rebar get-deps
./rebar compile
mkdir -p .eunit
erlc -o .eunit/ *.erl
erl -pa deps/meck/ebin/ -pa .eunit/ -eval "eunit:test([t1,t2])" -s init stop

Though, if checked separately, tests pass:

  Test passed.
