So RH is adding about, but it's actually only this that is triggering the error:
-flto=auto
Going to read up on what that does which causes:
error: call to ‘_curl_easy_setopt_err_write_callback’ declared with
attribute warning: curl_easy_setopt expects a curl_write_callback
argument for this option [-Werror=attribute-warning]
60 | curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION,
| ^
lto1: all warnings being treated as errors
Thanks.
