Putting a space there isn't even optional, it's wrong. The stuff after the space is not passed to the linker, it's interpreted by dmd.

I'm not sure if it's significant, but it's a difference. There are two ways in the doc you linked: dmd hello.d -L+gtkd.lib or dmd hello.d -Lgtkd.lib -m64 The second doesn't uses "+" but it has "-m64". Anyway even the example with "+" it doesn't working here either. Also, and this may be it, the link.exe that's distributed with dmd doesn't like forward slashes as path separators. You can try it with backslashes instead: dmd test.d -LC:\gtkd\src\build\GtkD.lib I had tried that before, without any success. -L doesn't take a space, either. Putting a space there isn't even optional, it's wrong. The stuff after the space is not passed to the linker, it's interpreted by dmd. In fact I already had understood what happened after your first answer, which "-L" with space wasn't been "evaluated" because DMD was reading a flag without arguments. So I could omit it there, but like I said, many examples out there uses: "-Lpath/to/whatever", and then you see many topics about people complaining about this. Bubba.

For example, I use "dmd -L/STACK:268435456" by default along with other options to increase the default stack size to 256Mb. Your comment is reasonable enough, but unfortunately the main problem is there are examples on the internet using this "-L" for this kind of thing. If go here: http://wiki.dlang.org/Compiling_and_linking_with_DMD_on_Windows#Static_Libraries_and_Import_Paths There is an example in: "Passing search directories for static library files to Optlink", which follows: C:\Project\main.d C:\Project\lib\mylib.lib where main.d depends on the mylib library, you can compile via: dmd -L+.\lib\ driver.d mylib.lib Yes there is a "+" plus sign and a "." dot there, but I believe people gets confuse and uses it as "-I". Clearly, the forward slash (/) is reserved for switches, so the program will have trouble parsing paths with forward slashes. About this in fact this was my mistake, because originally I had tried "\" and since it wasn't working so I change to "/" and that remains. Bubba.

I don't think that's right. Unless something awful is going in Windows dmd, that should be processed as two separate entities: "-L" passes nothing to the linker, and whatever you try to send the linker is interpreted independently by dmd. You can try removing the "-L" entirely. If it still works, then dmd is apparently able to handle things for you, and you don't need to go the linker yourself. What exactly are trying to pass to the linker? It took me 30 minutes until I find why my program wasn't compiling. (I found the tip on a forum elsewhere). Can you give a link to that?

I'm convinced that putting a space between "-L" and its argument is nonsense. The "-L" part just means "pass the empty string to the linker", which doesn't do anything. And the argument is interpreted by dmd then, not by the linker. What exactly are trying to pass to the linker? A lib: GtkD. That means a .lib file, right? dmd knows how to handle .lib files [1], so it's no surprise that things work when you pass the .lib file to dmd. The GtkD docs say to use -L though [2], so I suppose that should work too. Maybe show your exact complete command line, if you want to find out why it doesn't work for you.

Well this problem took only 30 minutes, because luckily I found the answer on the second link, but it could take hours. Bubba.
