Statically link it.

How can I do that? I have compiled my program with this command: 
"dmd -L-lphobos2 -L-lcurl test.d
"

Excuse me for that dumb question but I'm really new to compiled 
languages. I've written some code in Java but it's not the same.

Sorry for being noob but how I can do it?

You just gave me an idea to compile in shared libraries and then 
to extract them on run.
I'll let you know when I got some code.
(Btw this is not a good idea but definitely will work for license 
reasons, although this could be a rather gray zone. Should be 
confirmed.).

So I modified my Bin2D which allows compiling in resources[1].
Now it can produce an output file that when compiled in gives two 
new functions.
These functions essentially extract the files for you.
One of those is for temporary directory[2].

Little bit off topic but it can be utilised for packaging up 
shared libraries into your executable and then extracting on run.

E.g.
$ dub build
$ cd bin
$ ./Bin2D outputFile.d=outputModule lib1.so lib2.dll
Just an example usage. Note not on dub repository.

Just another option for ya.

Thank you for taking time and writing this tool but I don't 
really understand how to use it. Can you please explain it little 
bit more? So I have my main.d file with source code and I compile 
it with this command: "dmd -L-lphobos2 -L-lcurl main.d". How will 
I get all the libraries into one executable with Bin2D?

First I may have forgotten that phobos links with curl not loads 
at runtime.
So if your wanting to use shared libraries like this over static 
still.
You can basically compile normally.
Then $ Bin2D output.d=output main curl.so
Where main is the executable you built with dmd.
You will need to add a main function to output.d e.g.

import std.process;
void main() {
     string[string] files = outputBin2D2FS();
     execute(files["main"]);
}

Note that the usage of std.process is from memory.

Although I would highly recommend using static instead if you can.

On Linux, doesn't all distributions ship with libcurl by default? For 
Windows I found this:

I have no idea if it works for D.

Link statically with it, which is does by default. Just compile with:

dmd -L-lcurl test.d

Apparently you need to install the libcurl dev package. The linker can't 
find libcurl.a.

I've installed libcurl4-openssl-dev 7.29.0-1ubuntu3.1 before I

I don't see way explicitly linking with Phobos would make a difference, 
since the compiler will link with Phobos implicitly. That assumes you 
have libphobos2.a in /usr/lib/i386-linux-gnu or /usr/lib/x86_64-linux-gnu.

Did you try to use -static option of compiler? It forces to link 
application with static libraries instead of shared.

If you give the exact file name for the static library (e.g. 
/path/to/libcurl.a), then it should link against the static version of the 
library. Also, -L-static might help, as it tells the linker to only link 
static libraries.
