http://www.mkssoftware.com/docs/man3/curs_termcap.3.asp

extern(C):
int tgetnum(const(char) *capname);

calling a method from main
writeln(tgetnum(toStringz("li")));


I receive an error message
Undefined symbols for architecture x86_64:
   "_tgetnum", referenced from:
       _main in RSConsole.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to 
see invocation)


Does anyone know what the problem is?
Maybe there are other methods to get and set sizes of the Mac OS 
X console?

Try adding -lncurses or -lcurses to the command line. tgetnum is 
found in the curses library which isn't linked in automatically 
by default.

Try adding pragma(lib, "curses"); (or ncurses) to your file with 
main in it, i think ldc supports that.

pragma(lib, "curses");

extern(C):
int tgetnum(const(char) *capname);

hmm segfault error :(

It works fine on my 32-bit Debian with ldc2 and dmd.

I use
ldc2 main.d -L-lcurses
or
dmd main.d -L-lcurses

and following source code:

import std.stdio;

extern(C) int tgetnum(const(char) *id);

int main()
{
     writeln(tgetnum("li"));
     return 0;
}

Note that you don't need to apply toStringz to string literals 
since they implicitly cast to const char*.
