You should try to use https://github.com/BindBC/bindbc-opengl
and
https://github.com/BindBC/bindbc-sdl. There seems to be an
issue with
derelict packages (mainly with the gl3 one)
And as far as I know derelict should be replaced by bindbc
anyway in future.
And if you plan to have *.so libs you should add "targetType"
: "dynamicLibrary", to you dub.json
OK, thanks. That is useful to know. But just to not turn the
topic elsewhere I should make clear that:
1) I'm not speaking about OpenGL and SDL specifically (that was
just small example which I tried first)
2) I'm more concerned about how to D compiler links
dependencies when it compiles simple .d program (with lot of
dependencies).
I think if I can make it link everything dynamically, It would
considerably reduce both size of binary target (whether it is
executable or .so) and compilation speed (since it would not
re-compile dependencies).
What I want is to recompile and run quite large
programs/projects composed composed of many little
sub-programs/sub-libraries from Python+D in fast cycles (<< 1
second), because that would make debugging workflow much more
pleasant and efficient (in comparison to Python+C/C++ or Julia).
If you are building individual files, use ldc2 with
--link-defaultlib-shared flag:
arun@home-pc:/tmp$ cat a.d
void main() { import std; writeln("Hai"); }
arun@home-pc:/tmp$ ldc2 a.d
