An issue with EVP_PKEY_CTX_get0_pkey()?

[Blumenthal, Uri - 0553 - MITLL]

The problem manifests itself when I attempt to compile Ruby gem "openssl-3.1.0" (I doubt it relates to OpenSSL release 3.1.0, but I'm not sure).

It seems to be related to the fact that 'struct evp_md_ctx_st' is not available?

Here's the offending lines (I don't see any problem with them):

EVP_MD_CTX *ctx;
EVP_PKEY *pkey;

GetHMAC(self, ctx);
pkey = EVP_PKEY_CTX_get0_pkey(EVP_MD_CTX_get_pkey_ctx(ctx));

Here's the error message:

I'd appreciate any help or advice. Is it an OpenSSL problem? An openssl-3.1.0-rubygem problem? Do I need to report it on some Rubygems list?

Thanks!

There are two ways to design a system. One is to make it so simple there are obviously no deficiencies.
The other is to make it so complex there are no obvious deficiencies.
