Hi all,

Whilst building an RPM for Fedora using copr (and on my local Fedora
35), this error is generated:

In function 'test_http_api_health_check_version',
    inlined from 'test_http_api_get' at tests/unit_tests/test_http_api.c:115:2:
tests/unit_tests/test_http_api.c:60:9: error: call to

warning: curl_easy_setopt expects a curl_write_callback argument for
this option [-Werror=attribute-warning]

https://copr.fedorainfracloud.org/coprs/ghenry/SentryPeer/

yet it's set like the example:

https://curl.se/libcurl/c/getinmemory.html
https://github.com/SentryPeer/SentryPeer/blob/main/tests/unit_tests/test_http_api.c#L60

Anyone seen this before? Builds fine from source and on Debian and
Ubuntu etc. I wonder if this is Red Hats build options for RPMs....
