Hello,

I am wanting to create my own C bindings to CSFML, and I have 
been extremely struggling with this.

There is no resources or tutorials for how to do this so I am 
basically on my own.

First thing I looked at was `dstep` which helps translate C 
header files to D language, so I ran `dstep` and translated the C 
header files to D language. This went well. I ended up wrapping 
all the code in an `extern(C)` call.

Now, I am trying to 'link' CSFML to my bindings but have been 
struggling to do so.

I tried to add the following to `dub.json`:

```
"libs": ["csfml-audio", "csfml-graphics"]
```

But it came back with an error:

```
/usr/bin/ld: 
/home/tom/Desktop/sfmld-backend/out/production/sfmld-backend/
bj/sfmld-backend.o: in function `_Dmain':
/home/tom/Desktop/sfmld-backend/source/graphics.d:(.text._Dmain[_Dmain]+0x3a):

undefined reference to `sfRenderWindow_display'
collect2: error: ld returned 1 exit status
Error: linker exited with status 1
```

I am really confused as to how I even am supposed to get the 
library name in the first place, which is another thing that is 
confusing me.

Any help with this would be appreciated.

It is up to the library author to choose a name. The extensions 
is `.so/.dll/.dylib` for shared libraries on nix/Windows/Mac and 
`.a/.lib/???` for static libraries.

The second part, this looks like sfml graphics depends on sfml 
render or window or something like that, you'd better check 
`readelf -d sfml-render.so | grep 'NEEDED'` if you have dynamic 
libs to get a clue what it might need, or go search library that 
contains missing symbols by hand.
