Hi,
When we call emcc without an input file, we usually get a warning. I
noticed that when I call emcc from a Makefile, I always get these errors,
compilation does not stop but I get these "no input files" errors. Is that
the expected behavior?
Is there something I can do to stop getting this error, or investigate more?
