Work continues by the Apache developers on getting Apache 2.4 working with OpenSSL 1.1.0.
What seems to work so far:
httpd, yes mod_ssl will now build and seems to work fine with OpenSSL 1.1.0.
What does seems not to work yet:
abs, it builds but at this point it doesn't seem to work, not for me anyway.
apr_crypto_openssl.dll doesn't build (it's a different project of the ASF than the server) so there is no chance for mod_session_crypto at this time.
I have VC14 x86 & x64 preview builds for testing.
If anyone would like to take one for a spin reply to this post and I'll send you a link.
