Error compiling mosquitto with OpenSSL 1.1.1

[acode-x]

Hi,

I am currently using OpenSSL 1.1.1 with extended support. I noticed that the recent changes in PR #3050 always compiles mosquitto with OpenSSL 1.1.0, regardless of the available version.

OS: Ubuntu / Alpine Linux
Mosquitto versions: 2.0.19 and 2.0.20

Could you please help with same.

Thanks!

Thanks for the report. What errors do you get when compiling? The PR you reference just sets the API compatibility level. There aren't checks in the openssl source or headers that would be impacted by increasing the API compatibility level to 1.1.1, so I don't know what could be happening.
