epoint2_set No irreducible basis defined #82

Open BambooAce opened 4 years ago

BambooAce commented 4 years ago

epoint *p2 = epoint_init(); big x2 = mirvar(0); big y2 = mirvar(0); cinstr(x2, "6C997F3E7F2C66A4A5D2FDA13756A37B1"); cinstr(y2, "4A38D11829D32D347BD0C0F584D546E9A"); epoint2_set(x2, y2, 0, p2);

When call epoint2_set , the process crash, and display No irreducible basis defined

Hello

You need to make a call to

prepare_basis(m,a,b,c,TRUE);

before calling epoint2_set()

where m is the size of the field (as in 2^m) and a,b,c describe the trinomial or pentanomial basis for the field.
