This is because `OPENSSL_NPN_NEGOTIATED` macro always exists even if NPN is disabled. I attached a patch which fixes this. ---Files-------------------------------- 0001-openssl-fix-build-when-NPN-is-disabled-by-OpenSSL.patch (5.43 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
