Installing Charm-crypto-0.42- python2.7 with openssl 1,1, I am getting following error

[ck-chaudhary]

charm/core/math/integer/integermodule.c: In function ‘bnToLongObj’:
charm/core/math/integer/integermodule.c:96:19: error: dereferencing pointer to incomplete type ‘BIGNUM’ {aka ‘struct bignum_st’}
96 | for(i = 0; i < m->dmax; i++) {

I have gone through issue# 209 but it seems different.

Try dowgrading to openssl 1.0.0

OpenSSL 1.0.0 was released like 3 years ago. I imagine a lot of vulnerabilities was closed since then. And even if we put that aside, still downgrading openssl is not a solution.
