Your arc.ini is incorrect.
Code:
[External compressor:oo2reck,oo2recm,oo2recs]
header = 0
packcmd = {compressor} e <stdin> <stdout>
unpackcmd = {compressor} d <stdin> <stdout>
This is the packcmd given. {compressor} translates the name of the method into the exe file used for the method.
Put the oodle core in the same folder as the oodle precompressor. It will automatically use it.
Then your method: oo2recm+oo2recs+srep+lolz
