Configure error: checking if libcurl supports https... no

Sun, Aug 29, 2021 10:22 AM

Hi,
What you need is the libcurl library, not the program curl (which you 
have installed):

     sudo apt-get install libcurl4

and probably (if not installed automatically by apt):

     sudo apt-get install libcurl4-openssl-dev

Now it should work.

PS. you may always check which package provides a particular file by using:

     apt-file find libcurl

Regards,
Adam Wysoki?ski
