You need to install the development curl package:

That´s it.
Thank you!

Curl is installed, as also libcurl3.

Is std.net.curl working in this Version? Because it also didnt 
work on my Windows 7 System.


Do you know what the libcurl library is actually called on your 
system? (try "find /usr -name "*curl*.so*" " or "find /usr -name 
"*curl*.a*" )


if the name you find is e.g. "libcurl3.so" then you'll have to 
use the linker flag -lcurl3 instead of lcurl


p.s. Please don't be offended if you're already fully aware of 
this, it's just better to make sure the basics are covered first.

Try providing the directory that the curl library file is in:

#dmd hello.d -L-L/wherever/libcurl/is/in -L-lcurl

These functions are defined in libcurl. Make sure you have installed 
libcurl if it wasn't installed as a dependency for curl.

You have to link libcurl via argument:

  dmd hello.d -L-lcurl
