Dear all, I stumbled across this mails when looking for information regarding OpenSSL on zOS. Currently, I am working on getting OpenSSL 1.1.1c running on zOS. So far I created my own config "target" inside 10-main.conf based on the old configuration that was used pre OpenSSL 1.1.0. Still, I was not able to get that far yet and was wondering how you proceeded regarding this issue? Apart from some github issues and the likes regarding EBCDIC patches I was unable to find much advice on how to configure the build and how to tackle common issues. One config target for zOS OS390 was created a while back but then removed again from OpenSSL 1.1.1. With my config target I made it to the compile step but still face build issues. Reaching a complete build like Wendell Nichols would already by a great step. Are any of you aware of zOS specific OpenSSL development branches that I have yet to find? Or is this mainly done in private repositories/branches and not offered for PRs to the OpenSSL repository? Any advice is greatly appreciated. -- Sent from: http://openssl.6102.n7.nabble.com/OpenSSL-User-f3.html
