digitalmars.D - D and shared librery

Hi,

I didn't find resources on what are actually supported with D and 
shared library.

I need to reduce binary size, so I would like to ship all 
dependencies as shared

I read on some forum that shared library is conflicting with 
garbage collection of the druntime ?

I absolutely need shared library due to space constraints (and 
multiple binaries  ),so I need to know if D should be abandoned.

Thanks

You should abandon D if you require (hard no compromise):

1) Shared libraries (D, not e.g. C)
AND
2) Languages features like classes (and with it type info)
AND
3) Cross platform support (Windows mostly is the problem atm)

Some may say, but it works for me! But it doesn't work for most users. 
It simply hasn't been designed as an experience.

Shared libraries are working fine on Linux and OSX.
For example, on ArchLinux LDC builds shared libraries by default.
Maybe you have recently run into an issue on Windows and are 
frustrated because of this?


 AND
 2) Languages features like classes (and with it type info)


What's wrong about D's classes?


 3) Cross platform support (Windows mostly is the problem atm)

 users.

I hear a lot of frustration here, but even though one might hit a 
bump here and there, it doesn't mean that D hasn't been designed 
to have a nice experience.

Did you post your issues to the #dbugfix campaign?

For macOS LDC is required.

I haven't heard about issues with this.
Also the garbage collection is enabled lazily since 2.080.
Druntime itself can be linked as a shared library too btw.

On which OS/architecture do you plan to ship your binaries?
D doesn't have full support for creating Windows DLLs, but 
there's active work on this:

I'am targeting linux-gnueabi on ARM, but currently doing some 
local test on my x86 linux.

Using ldc2 do you have some example ? (building a shared library 
and linking it in another app)

Thanks
