your code just return result value,

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.
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.

[CSFML](https://www.sfml-dev.org/download/csfml/) library dlls in

I will try to make it work... Meanwhile, if someones spots what I
am doing wrong, please reply to this post.

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...

Re: Failed to archive JPEG (ArchiveMember): Invalid UTF-8 sequence (at index 1)

Read it with `std.file.read()` instead of `readText`. Then you can get rid of those useless dup.representation calls too. Thank you for such a quick reply! It solved my issue!
Failed to archive JPEG (ArchiveMember): Invalid UTF-8 sequence (at index 1)
Please, help me solve the annoying error above. I've been
refactoring and rewriting code for my archive utility called
[zippo](https://github.com/rillki/zippo) and I face this error
when it tries to archive a JPEG image.
I tracked it down to the following function that helps me add a
new member to `ZipArchive`.
```D
void zipAddArchiveMember(ref ZipArchive zip, in string file) {
import std.conv: to;
import std.file: readText;
import std.string: representation;
ArchiveMember member = new ArchiveMember();
member.name = file;
writefln("%s", file);
member.expandedData(file.readText().dup().representation());
member.compressionMethod = CompressionMethod.deflate;
zip.addMember(member);
}
```
Am I missing something?

Via `lflags` section? What if I put them in a different folder instead of the project's directory? Yes. The path goes in the lflags directive using whatever the linker-specific flag is. I assume for lld it's `-Lpath`. For MS link it's `/LIBPATH:path`. I've added lfags: ``` "lflags": ["/LIBPATH:C:\\Users\\Username\\Desktop\\test\\source\\"] ``` But now it cannot find the following: ``` msvcrt120.lib OLDNAMES.lib shell32.lib ``` I think `lfags` overrides the default search path and I need to add it manually as well. But what is that path on Windows?

If you don't, it will use the lld linker it ships with. Either way, you need to raylib to be compiled with he same version of the MS Build tools so that you don't have conflicts the the vs runtime. Indeed, DMD used the lld linker.

I got it working with `raylibdll.lib`! SOLUTION: 1. `dub init` 2. `dub add raylib-d` 3. download `raylib` pre-compiled [binaries](https://github.com/raysan5/raylib/releases) for Microsoft Visual Studio (msvs) 4. put `raylib.dll` and `raylibdll.lib` into your project's folder (into the same directory, where you have `dub.json`) 5. add `"libs":["raylibdll"]` section into dub.json Compile and run. It should work.

Do you have any ideas? raylib.a isn't going to get you anywhere. You'll run into issues mixing MinGW-compiled libraries. If raylib doesn't ship precompiled VS binaries, then, assuming you have Visual Studio (or the MS Build tools) installed, you should compile Raylib with that same version. Then you'll have a new raylib.dll and a raylib.lib. Add raylib.lib to your dub config via the "libs" directive. I have downloaded the pre-compiled binaries from the official [Raylib ](https://github.com/raysan5/raylib/releases/tag/3.7.0) repo. I'm not using Visual Studio. Only dub and a text editor.
