Works fine now, thanks!

Addtional dependencies have been added by the following commit: https://git.savannah.nongnu.org/cgit/dkgpg.git/commit/?id=797580e66434d639a29de11b94297aef90dfe6a7

I've successfully run the tests with -j<n> for n = 1..8.

Program t-dkg-sign with parties P_1, P_2, and P_3 ("Test2", "Test3", "Test4") fails with the following error messages:

P_2: second ZNPoK in Step 2d failed for P_1
P_2: third ZNPoK in Step 2d failed for P_1
P_2: there are extracting complaints of v_j against P_1 but ignoring P_1
P_2: signers (index from DKG) in Step 2f: P_2 P_3
P_2: not enough cooperative players (< 2t+1) for signing

It seems that parallel execution of t-dkg-refresh causes this error, because shares of parties P_0, P_2, and P_3 have been refreshed.

I will add some more dependencies soon.

The tests are happy if I drop the '-j5'.

Thanks for reporting. I've fixed that bug by adding required dependencies to Makefile.am with the following commit:

https://git.savannah.nongnu.org/cgit/dkgpg.git/commit/?id=5aa9fc591b5971cc5a89b6a33c2a0a3aab9ed243

Please, can you confirm that it works?

Running e.g. 'make -j check' fails because some tests depend on key material being generated as a side-effect of running other tests, and this dependency is not taken into account when running the tests in parallel.
