I don't think there's any such thing as "static dll"s and "dynamic
dll"s.  I think you have your terminology mixed up.

A "static library" is a bundle of code and data, and so is a "dynamic
link library" (which are commonly called "DLLs").  The difference is
that a static library is designed to be linked into a program at compile
time, and a DLL is designed to be linked into a program at run time.

Static libraries are generally .lib files, whilst DLLs are .dll files.

The only other thing to be careful of is that there are various kinds of
.lib files, not all of which are compatible with each other.  For
instance, DigitalMars' linker doesn't work with .lib files compiled for
current versions of Visual C++.  DLLs, on the other hand, tend to work
fine once you're got an interface for them.

Hope that helps.

imho, sometimes this terms used (may be not correctly?) to distinguish dll
loading method.

"static dll" sometimes means "compiler-handle dll loading". in this case you
just say to compiler, that you want to use exterlanl function in some dll. then
compiler generate exe such manner, that OS or helper code must load needed dll
while exe starting. in windows it create import section in exe file, so windows
must load dll or generate error else.

"dynamic dll" sometimes means "programmer-handle dll loading". in this case
programmer write own code to find and load need dll and unload it if it not
needed. in windows it can be done with LoadLibrary() api function.

i am repeat, that i can mistake and termynology misunderstanding.

I've been trying to statically link a d program with a dll that calls d code
(http://www.digitalmars.com/d/dll.html) and i can't get it to work. I tried the
example that comes with the compiler and works fine but it looks like it
doesn't work with namespaces. For example replace the module namespace in the
example from mydll to mydll.example.

Have somebody get it to work this way?

I've got one more question related to this. I must import something in my
program to access the dll, what should i import? the entire module's namespace?
ie: mydll.example. or the name of the dll. I'm having a bit trouble here.
