Just mentioning, cause it took me some time to find the necessary packages:

sudo dnf install g++ libcurl-devel libconfig-devel libmicrohttpd-devel

And it seems you have to pass -fpermissive to g++ (i.e. in the Makefile), to allow the compilation to go through. Or to fix the "invalid conversion error".

Hi,
Could you remove ".onion" in the new url: TorHostxxxxxxx.onion.torgate.test to TorHostxxxxxxx.torgate.test, i'm not a developer, and tried to edit the code, but it's not working on some sites with url rewrite (like http://zqktlwi4fecvo6ri.onion/wiki/index.php/Main_Page ).
Also, options curl_connect_timeout and curl_timeout in config file would be nice, since those don't seem to have default value.

Cheers!
