Hi, recently I compiled openssl-1.1.1k on CentOS-8 but when I am using libcrypto.so.1.1 I get errors like: libk5crypto.so.3: undefined symbol: EVP_KDF_ctrl, version OPENSSL_1_1_1b Obviously RedHat added additional features into there own libraries, but using the same version/naming. See https://bugzilla.redhat.com/show_bug.cgi?id=1829790 I tried also to apply the patches, but they don‘t work with the latest source code https://git.centos.org/rpms/openssl/blob/c8/f/SOURCES/openssl-1.1.1-evp-kdf.patch The suggested solution renaming the libraries didn‘t work neither for me. But we want to use the latest version, including all security fixes, therefore I can‘t use the build-in version. Has anybody a solution for this? Is it planned to implement such features in official OpenSSL in the near future? Kind Regards, Lothar
