Well, `bin/` and `libs/` are in the same directory.
When dub runs the exectuable, it sets the current working
directory to the project's root directory by default.
`setCustomLoaderPath` passes whatever you give it directly to
the system API unmodified. You've passed a relative path. By
default, the system API associates relative paths with the
current working directory.
So given a project root directory of `$ROOT`, and your
executable in `$ROOT/bin`, the system is looking for the
libraries in `$ROOT/libs` and *not* in `$ROOT/bin/libs`. If the
libs are in the former, everything loads. If they're in the
latter, then it's going to fail.
If you cd into `bin` and run the executable manually, then libs
in `$ROOT/bin/libs` will load, as your current working
directory is `bin`.
The quick fix for this is to add `"workingDirectory" : "bin"`
to your dub.json. Then your relative paths will be relative to
`$ROOT/bin/`.
I tried `bin/libs/` as well as you describe here. It did not work.

Actually, it is quite strange that it fails to load the
[CSFML](https://www.sfml-dev.org/download/csfml/) library dlls in
`libs/` (I download CSFML2.5) since that is what I do with
[GLFW/OpenGL](https://github.com/rillki/d-glfw-opengl-project-template) example as well for Windows 10.
**Even this fails: `loadSFMLGraphics("libs/csfml-graphics.dll")`**

I've tried your project out two ways, one that succeeds and one
that fails. I'm guessing you've put your 'libs' directory is
'bin/libs'. Am I right? If so, then the following should help you.
When dub runs the exectuable, it sets the current working
directory to the project's root directory by default.
`setCustomLoaderPath` passes whatever you give it directly to the
system API unmodified. You've passed a relative path. By default,
the system API associates relative paths with the current working
directory.
So given a project root directory of `$ROOT`, and your executable
in `$ROOT/bin`, the system is looking for the libraries in
`$ROOT/libs` and *not* in `$ROOT/bin/libs`. If the libs are in
the former, everything loads. If they're in the latter, then it's
going to fail.
If you cd into `bin` and run the executable manually, then libs
in `$ROOT/bin/libs` will load, as your current working directory
is `bin`.
The quick fix for this is to add `"workingDirectory" : "bin"` to
your dub.json. Then your relative paths will be relative to
`$ROOT/bin/`.
Bear in mind that when using relative paths like this, any file
reading is bound to break if someone runs your executable from
outside its directory. You can test this by going into `$ROOT`
from the command line and executing
`bin/d-sfml-project-template`. Then you'll be doing the same
thing dub does, i.e., your working directory will be `$ROOT`.
The way to guarantee your relative paths are always relative to
the executable are to either set the current working directory to
the executable's path, or to prepend all relative paths with the
executable's path before handing them off to the system.
There are two ways you can get the full path to the executable in
Phobos/DRuntime: via `std.file.thisExePath`, or
`core.runtime.Runtime.args[0]`. (The former is failing to compile
for me on Windows right now due to a bug in the Phobos Win32 API
bindings. I'll look into it.)
Strip the file name from the returned path, then you can use it
as required.

I tried following the instructions, it builds successfully,

In particular, `loadSFML, loadSFMLGraphics, loadSFMLXXX`
fails. Here is

Not without error messages. The first thing you should do is
use the error API in bindbc.loader to print them out. That
should tell you what the problem is.
I forgot about that). Here are the errors that occur on Windows:
```
csfml-system.dll, The specified module could not be found.
csfml-audio.dll, The specified module could not be found.
csfml-audio-2.dll, The specified module could not be found.
csfml-audio-2.0.dll, The specified module could not be found.
```
Why can't it find these libraries? I tell where to look for them:
```D
version(Windows) {
import bindbc.loader;
setCustomLoaderSearchPath("libs"); // tried using absolute
path as well
}
```
That is strange...

I installed it on my Linux system without using a loader and with
static SFML. I just used apt-get and dub. I did the following in
order:
1. sudo apt-get install libsfml-dev libcsfml-dev
2. dub init dsfml bindbc-sfml
3. cd dsfml
4. edit dub.json and add:
```java
"libs": [
"csfml-audio",
"csfml-graphics"
],
"subConfigurations": {
"bindbc-sfml": "staticBC"
},
"versions": [
"SFML_Audio",
"SFML_Graphics"
],
```
5. dub
**app.d**
```d
import bindbc.sfml;
void main()
{
sfContextSettings* settings;
sfEvent event;
auto window = sfRenderWindow_create(
sfVideoMode(750, 500),
"Japanese Flag",
sfWindowStyle.sfDefaultStyle,
settings
);
auto flag = sfCircleShape_create();
flag.sfCircleShape_setRadius(150);
flag.sfCircleShape_setPosition(sfVector2f(225, 100));
flag.sfCircleShape_setFillColor(sfRed);
while(window.sfRenderWindow_isOpen())
{
while(window.sfRenderWindow_pollEvent())
{
if(event.type == sfEventType.sfEvtClosed)
{
window.sfRenderWindow_close();
}
}
window.sfRenderWindow_clear(sfWhite);
window.sfRenderWindow_drawCircleShape(flag, null);
window.sfRenderWindow_display();
}
}
