I am (in principle for this project) using what I get from LuaRocks.
$ luarocks show lua-curl
Lua-cURL 0.3.6-1 - Lua binding to libcurl
License: MIT/X11
Homepage: https://github.com/Lua-cURL
Installed in: /usr/local
Modules:
cURL (/usr/local/share/lua/5.3/cURL.lua)
cURL.impl.cURL (/usr/local/share/lua/5.3/cURL/impl/cURL.lua)
cURL.safe (/usr/local/share/lua/5.3/cURL/safe.lua)
cURL.utils (/usr/local/share/lua/5.3/cURL/utils.lua)
lcurl (/usr/local/lib/lua/5.3/lcurl.so)
I have verified that the problem is present also if I require 'lcurl'
rather than 'cURL'.
My system is Ubuntu 16.04.2 LTS .
