OpenSSL 4.0 removed the ENGINE API. <openssl/engine.h> still exists as a source-compatibility stub, so both binaries fail to link: ld.lld: error: undefined symbol: ENGINE_load_builtin_engines ld.lld: error: undefined symbol: ENGINE_by_id ld.lld: error: undefined symbol: ENGINE_init ld.lld: error: undefined symbol: ENGINE_ctrl_cmd_string ld.lld: error: undefined symbol: ENGINE_load_public_key The ENGINE use is confined to the "pkcs11:" input branch of each tool, so compile that branch out on OpenSSL 4 and diagnose the unsupported input instead. Reading certificates and public keys from PEM files, which is what the kernel build and most other users do, is unaffected. Providers supersede engines, but none exposes an equivalent of the pkcs11 engine's LOAD_CERT_CTRL command, so there is nothing to port to yet.
