You have to link libcurl via argument:

  dmd hello.d -L-lcurl

Thank you for answering. But it didnt work.

I get:
#dmd hello.d -L-lcurl
/usr/bin/ld: cannot find -lcurl
collect2: ld returned 1 exit status

Curl is installed, as also libcurl3.

I forget to mention that i am using "DMD64 D Compiler v2.062".
Is std.net.curl working in this Version? Because it also didnt 
work on my Windows 7 System.

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

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

You need to install the development curl package:

$ sudo apt-get install libcurl4-openssl-dev
or
$ sudo apt-get install libcurl4-gnutls-dev
or
$ sudo apt-get install libcurl4-nss-dev

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.

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