A cross-platform betterC compatible shared library loader for D bindings
RiverD is a project to create static and dynamic binds to all C libraries. The intent is to make a standard loader and allow users to use or not -betterC, @nogc or even nothrow.
At the moment, our mixin builder don't support -betterC, so you need to make it manually (D compilers can't evaluate CTFE with GC dependent code using -betterC).
Using RiverD builder, you need to specify a types module containing all the types to be used on your C functions, a dynfun module containing __gshared symbols and import to types (for function types), a dynload module containing the import of dynfun module and this piece of code:
mixin(DylibLoaderBuilder!(dynfun));Additionally, you have statfun module for static linkage support containing extern(C) functions declarations.
Using RiverD loader manually you can adapt this code for dynload module:
void* dylib_load_libname() {
void* handle = dylib_load("libname.so");
if(handle is null) return null;
dylib_bindSymbol(handle, cast(void**)&libname_symbol, "libname_symbol"); //make this for every function symbol
return handle;
}void* libname_handle = dylib_load_libname(); // load
dylib_unload(libname_handle); // unload
bool loaded = dylib_is_loaded(libname_handle); // isloadedCheck out our wiki.
