I am trying to compile ChatScript but I get this error message:
json.cpp:474:23: fatal error: curl/curl.h: No such file or directory
When I try apt-get install curl it says:
curl is already the newest version (7.47.0-1ubuntu2.7).
I also tried to install curl-devel and libcurl but I get:
E: Unable to locate package ...
Why this error happens and how can I fix it? I am using Ubuntu-server 16.04 sunxi-arm7.
