/demo/ers-etrs code running error

another-ed commented 8 months ago

Hi! I'm studying https://eprint.iacr.org/2021/1240, so I downloaded the relic-0.6.0 library and installed the GMP library. After that, I executed make in the demo/ers-etrs directory. It was compiled successfully, but it got following errors when I run it,

It seems that cp_ers_ext function has some errors. Notes I initially used git clone https://github.com/relic-toolkit/relic.git, but encountered the same issue as #279 during the compilation.

I pushed a number of fixes to HEAD that should close the issue. Can you please try again?
