Re: Another opportunity for a major design win has presented itself
If option -shared is selected, will it automatically generate as PIC, or do you have to also specify -fPIC? When I used gfortran, it was -shared only on windows, on linux both options: -shared and -fPIC. Was obtained empirically.

I want to get the next release out, first, and then we'll get the shared library thing working.

Pull requests only needs to be merged to druntime I guess :) (b) improve language safety without degrading efficiency (c) improve quality as always Of course, these things benefit pretty much all D users anyway. Initially, (a) is the most important.

To get the design win, we need to: (a) get dynamic linking and loading to work Which platform? Loading a single dynamic D library or multiple libraries? What language will the hosting app be written in? What are the parameters for the dynamic library interface? ie. extern C? D functions? UDTs as well? Might exceptions be thrown across the library boundary? Portions of this work better than others and it would help to know where to focus our efforts.

Initially, (a) is the most important. Consider that there are apparently problems when linking and loading D libs into C/C++ apps. I was told that the GC won't work correctly, but I'm no longer sure exactly why. If we can safely link+load shared D libs into C/C++ apps, it is not only useful to have right now, but it also opens up a safe migration path for C/C++ users to start using D with their existing C/C++ apps, and if it works well, they may start using D fully. --rt

A D app consisting of a main D exe with multiple D DLLs that can be loaded/unloaded at runtime will work.

Re: Another opportunity for a major design win has presented itself
The compiler currently has an option -shared for generating a shared library. It also has an option -fPIC for generating position independent code. If option -shared is selected, will it automatically generate as PIC, or do you have to also specify -fPIC? --rt

It is like the news: Things boil up, get covered for a week and disappear from public sight for a year. It has been an issue but people have probably arranged with static linking for now or not started to write a particular program in D. I remember I've tried to use structs with const members for a while for example, but arranged with making every field mutable. Now the topic showed up again after months. -- Marco
