Hai all,

Compiling MonetDB Mercurial source on macOS Catalina (10.15.4) results in the following error:

/Users/jennie/monet/Nov2019/common/utils/mcrypt.c:476:3: error: 'CC_MD5_Final' is deprecated: first deprecated in macOS 10.15 - This function is cryptographically broken and should not be used in security contexts. Clients should migrate to SHA256 (or stronger).

How can I get rid of this error? Disable -Wdeprecated-declarations? Or disable MD5 but use SHA256 instead?

Thanks! Jennie
