java.lang.RuntimeException: Unexpected "end-of-file"

Hi

I follow the tutorial and I am trying to run:

./pepper_compile_and_setup_V.sh mm_pure_arith mm_pure_arith.vkey mm_pure_arith.pkey

and I get the following error:

Thanks in advance

Hmm, did you modify apps/mm_pure_arith.c? It looks like the compiler is failing to parse that file. I can reproduce your error if (for example), if I delete this line: https://github.com/pepper-project/pequin/blob/2b172e3615a5f1cf0c1977883d47dd4bc6b17d7e/pepper/apps/mm_pure_arith.c#L30

But it should compile if you use the checked-in version.

You are right my mistake. For some strange reason the file was empty. Probably I shouldn't tried after a lot of hours reading about zkSNARKs theory :).

Sorry for posting.
