LibCurl: how do I compile the example code?

Question

I have install libcurl by running:

sudo apt-get install libcurl4-gnutls-dev

Now, the folder locates at my /usr/share/doc/libcurl4-gnutls-dev/examples$.

Say I want to compile ftpget.c. How do I do that?

Solution

1. copy the source file to a directory where you have write permissions (so that the compiler is able to create the executable) e.g.

   mkdir ~/src && cd ~/src
   cp /usr/share/doc/libcurl4-doc/examples/ftpget.c ./
   

2. compile and link the file using gcc

   gcc -Wall -o ftpget ftpget.c -lcurl
   

This will create an executable called ftpget which you should be able to run from the current directory using ./ftpget
