Without this patch, maintainer builds of coreutils fail on Ubuntu 22.04 with diagnostics like "./lib/gl_openssl.h:79:1: error: 'MD5_Init' is deprecated: Since OpenSSL 3.0 [-Werror=deprecated-declarations]". From <https://wiki.openssl.org/index.php/OpenSSL_1.1.0_Changes> it appears that Gnulib needs to either define OPENSSL_API_COMPAT to a version less than 3.0, or use a compatibility layer, or assume OpenSSL 1.1.0 or later. The simplest workaround is to define OPENSSL_API_COMPAT for 1.1.1, the oldest OpenSSL release still supported. A better fix would be to rewrite the code to assume OpenSSL 1.1.1 or later, and stop using the older API. * lib/md5.h, lib/sha1.h, lib/sha256.h, lib/sha512.h, lib/sm3.h: Define OPENSSL_API_COMPAT to 0x10101000L to suppress the deprecation warnings on Ubuntu 22.04. --- ChangeLog | 18 ++++++++++++++++++ lib/md5.h | 3 +++ lib/sha1.h | 3 +++ lib/sha256.h | 3 +++ lib/sha512.h | 3 +++ lib/sm3.h | 3 +++ 6 files changed, 33 insertions(+)
