std.net.curl problem
hi there,
i am a newbee with d , just trying get a hold of the language, 
i've written small fragment of code that simply retrieves a page 
from a website and prints it to the console, but on compiling it 
i get the following error

It looks like you're not linking against libcurl. You need to explicitly pass 
a flag to dmd to tell it to link. If you were on linux, it would be -L-lcurl. 
It's something similar for Windows, but I don't remember the exact syntax.

No, the undefined symbols are D (mangled) symbols. It's probably this
bug:
http://d.puremagic.com/issues/show_bug.cgi?id=7561

But that should be fixed in dmd 2.060:
https://github.com/D-Programming-Language/phobos/pull/613

@adi which dmd/phobos version did you use to compile your code?

Thanks jonathan  for the pointer if you could help me with the 
complete solution that would be great as i have no knowledge of c 
as such , i am using D version 2.0.60 and visuald as the IDE 
solution
