Hello everybody,

I'm trying to compile a c programe that uses libcurl under Ubuntu 12.04,
Libcurl is correctly installed (I hope). but the linking is not working

gcc -lcurl functions.o main.o -o myprogram

I'm gettings these errors :

functions.c:(.text+0x5): undefined reference to `curl_easy_init'
functions.c:(.text+0x23): undefined reference to `curl_easy_setopt'
functions.c:(.text+0x2b): undefined reference to `curl_easy_perform'
functions.c:(.text+0x38): undefined reference to `curl_easy_cleanup'

Does anyone have an idea how can i fix it ?
Thanks ! :)

dpkg --list | grep curl
