Please run "dub remove-local C:\Users\Darren\D stuff\opengl\lib". whenever dub gets used. Then if I run what it says I get: "Missing path to package." Is there a way to return this to a default setting? If you have not changed anything in the dub.json file, then run "dub build" to rebuild the packages OR try clearing the dub cache and rebuild. I'm not really familiar with C++ - D bindings (I never wrote C++ code beyond printing a helloworld to the screen). The How To tutorials at https://wiki.dlang.org/Tutorials may help you with bindings and linking process.

I think I need to start before that, haha.
I might need more of a step-by-step guide. I'm a complete
beginner to programming, not just D. I worked through
Programming in D, where I was just compiling with dmd, then
when I decided to learn OpenGL I seem to be using dub for
everything.
There have been a few libraries I've wanted to use but
couldn't because they didn't have a pre-compiled binary, which
is all I've been able to get working through sheer trial and
error. Some sites say to use things like CMake and cygwin,
but I'm uncomfortable using things I have no idea about.
Dub is like a package manager for D (like what npm is to
node.js). All dub libraries are hosted at code.dlang.org. When
you see a library at code.dlang.org you want to use, you could
either type "dub install packagename" whilst in the dub project
ROOT or specify dependencies in the dub.json file.
You can then run "dub run" which will take care of fetching and
building dependencies/libraries from code.dlang.org (including
linking and running the binary).
For example, there is a web framework called vibe.d. If I want
to use vide.d, I can specify dependencies as;
dependencies: {
"vide-d":"^0.7.29"
}
In my app.d file (which is available for any dub project
created using "dub init projectname") I can import vibe.d using;
import vide.d;
void main() {
...
}
I can now compile and run the program with "dub run" or "dub
build" to only build and link without running.
Thank you! This does seem to work for packages listed on the dub
page (tested it with gl3n).
Would you be able to tell me how to install libraries that aren't
written in D? A lot of what I need to use are written in C/C++,
and I've use dub for bindings to those binaries. But what if I
need to compile/build those libraries from scratch, or use/link a
static library?
I'm not sure if there's a simple answer to this question but I
could do with guidance with how to use those libraries with D
(other tutorials just focus on C++ with Visual Studio, etc).

Hey, all
I keep hitting roadblocks and that's mainly due to not knowing how to
include libraries. So far I've been getting by with downloading .dll's
and including the necessary dependencies in the dub.json file and having
that build/run my project. I'm sure I'm making a mess of that, too, but
it works and now I need to learn how to include static libraries (and
probably understand github and other dub features).
Right now, for example, I want to use the gl3n package:
https://github.com/Dav1dde/gl3n
What do I need in order to build libraries, and have dub include them
when I import modules? Can I keep all of the libraries in one place so
I'm not copy-pasting them (like in lib and bin folders that I keep seeing)?
As you can tell, I'm still very new to all of this and I have no idea
where to start. Thank you for your time!
Ok lets start at the very beginning with straight dmd.
You have a total of two things you can pass in, an import directory and
source files.
Source files are compiled in and import directories are basically a way
to tell the compiler that certain symbols can exist but it won't create
them.
Now from this you abstract away into dependencies such as packages /
subpackages.
This is where dub comes in, it will fetch (known) projects with dub
definition files (dub.json/sdl), place them into a folder under your
profile directory and allow you to build against them and automatically
provide them as import directories as required.
So how do you do that? Simple.
"dependencies": {
"mypackage": ">=0.0.0"
}
Inside of a dub.json file (sdl is a little different check
code.dlang.org for more help on the subject).

Using libraries for (Postgre)SQL for bilingual (C++ and D) project
Hello! I have a project, which consists of 2 parts: web part (based on vibe.d) and core part (C++/Qt 5.5.x). Core will be used in a shared object (c-style exported functions). Both parts must interact with PostgreSQL. Core dynamic library will be contributor to my database (INSERTS/UPDATES), while vibe.d part will use SELECTs for views. Which C++ and D libraries for SQL queries should be used in order to minimize boilerplate code? I don't mind against ORM, using plain old objects (PODs) with special attributes. BTW, I've read about https://github.com/chrishalebarnes/quill.d.
