The library has an unresolved symbol:

$ nm ./work/HEAAN-2.1-39-gb2edd4c/HEAAN/lib/libHEAAN.so | c++filt | grep operator
                 U NTL::operator<<(std::basic_ostream<char, std::char_traits<char> >&, NTL::ZZ const&)

Have you compiled and installed NTL properly? NTL is not HEAAN nor part of it, but needed.

Answer 3 · 2020-02-19T16:00:06.000Z

Have you compiled and installed NTL properly?

It is linked with libntl.so but this symbol isn't present there.

Answer 4 · 2020-02-19T18:04:25.000Z

Well, for me it works.
Have you added ntl after heaan or before? Order matters.

This doesn't happen any more.
