I have installed yun-gcc and libcurl but it is not possible to compile and link my sources because <curl/curl.h> (or just <curl.h>) is not present on the yun.
It seems that opkg does not install all required files which should come together with libcurl.
If for example I install the libcurl4-openssl-dev package on my Linux Mint PC, I get all required files, including a lot of documentation and example-sources (and it works !).
Does something similar exists for the Yun ?
