Re: Trying to build libssh

[Jakub Jelen <jjelen@xxxxxxxxxx>]

Hi,
you seems to have some non-standard OpenSSL version installed. There
is a patch (already part of master) that detects the FIPS_mode() macro
and gracefully falls back if not found:

https://gitlab.com/libssh/libssh-mirror/-/commit/0d4658740b4a7f94cdbbfaa6d4d7dbc047660d4c

If it will work for you, I will backport it to th 0.10.x branch for a
next release.
