I don't know what is supported by OpenSSL, but it didn't build on several old
but still supported distros. I'll dig out the details I can easily get if
The HISTORY section of a modern (1.1.0g) man page says:
EVP_MD_CTX_create() and EVP_MD_CTX_destroy() were renamed to
EVP_MD_CTX_new() and EVP_MD_CTX_free() in OpenSSL 1.1.
The old code used the old names. When I was working on that area, I was
working from a modern man page so I used the modern names. The old names are
/usr/include/openssl/evp.h:# define EVP_MD_CTX_create() EVP_MD_CTX_new()
So (slightly) old code still builds on modern systems.
(That man page is buggy in that it doesn't mention the corresponding init=>
So rather than switch to the old names, I hacked in a couple of reverse
aliases that make the new code work on (slightly) old systems.
I don't think it's worth changing waf. I don't know how to determine the
correct minimum version number. It might be appropriate to add a link to
attic/digest-find already prints out the version number. I just added the
These are my opinions. I hate spam.
