Isn't there a way to compile it using gdi32.dll instead of statically linking the whole gdi library? The resulting 91K exe is a bit much.

Actually gdi32.lib has little actual code in it.  It just provides symbolic linkage to the DLL.  Also you probably need to look a the space a simple hello world takes up, some people remark that the D runtime is a little large.  It's all a trade off.  Most runtimes don't have a GC in them.

Wow... you're right... I didn't realize how large the hello world sample really was.

Having said that however... getting back to my original question, is there any way to compile it using gdi32.dll instead of statically linking the whole gdi library?

read the reply, gdi32.lib is the lib to link your app to gdi32.dll
gdi.dll is 218K on my machine (win2K)  check your gdi32.dll if its more than
90K the obviously your app does not have it statically linked.

the size of your app is due to the size of the phobos+gc libs which are statically linked.

Again: gdi32 *code* is not linked into an application. gdi32.lib is a "stub library", which contains no real code, but simply loads *the functions you use from the DLL* into your application at startup. It doesn't actually increase the executable size.

Your example is not really large. Consider: if you compile hello-world with DMC, you get about 45K executable. It contains a few parts of C library. Now, phobos partially wraps C library, and also adds a couple of dozen kilos for a GC and somesuch. Now, there you have it. it simply *can't* be much smaller than that.

I assume DMC links C standard library into the executable, else the minimal program size would go down to 8 kilobytes. LCC-Win32 and some versions of MingW use M1cro$oft's msvcrt.dll, which is almost 300K large and is distributed with W1nd0w$, and is a C standard library implementation.

Unless the library is moved into a DLL, the size won't go down.

BTW, is there an *easy* way to make shared libraries of object code, which would probably work with only one compiler, but would requiere no changes in source? Delphi allows to use its DLL derivate, simply create a "package" and specify "use run-time packages" instead of "link with packages" when compiling applications.

-i.

Why is phobos.lib really linked in the hello world sample program if none of
its
function is used? I think that the linker should exclude functions which are
not used.
Even the GC should be excluded if no objects are allocated.

Can we develop a more powerful linker without giving up the classic
compile/link model?
Anyway, I think that a cleverer linking system is worth the drop of that
model.

Thanks Ilya... your very kind, considerate, and thorough reply is most welcome. I now understand.

Thanks again... Gary.

The gc adds some code (maybe 40k). A big chunk comes, however, from all the unit tests in phobos.lib. Those should be removed from a release build, it is built now with all the debug checks and unit tests on.
