digitalmars.D.learn - Making a DLL with a static library dependency

(D 2.033) I'm porting a DLL to D. The DLL depends on a static library, but  
when I put the library name on the command-line, dmd does not output any  
DLL file. If I remove the library name from the command-line, dmd gives  
linker errors and outputs an invalid DLL. How do I make a DLL with a  
static library dependency?

Actually, it depends on another DLL. The static library I need to link to  
is an import library for that DLL. I'll work on loading that DLL without  
the .lib file using the Windows API while I wait for an answer here.

I'm not sure if the Windows loader does such chained DLL loading.
But you can always use LoadLibrary & GetProcAddress for that purpose.

Well... dll that can't call any function from kernel32.dll is practically
useless.

It worked fine in C++.

(now using D 2.037) I used optlink separately from dmd to see whether the  
problem is in dmd or optlink. It turns out to be an optlink issue.  
Everything works fine when I link in phobos.lib and kernel32.lib, but as  
soon as I link in lua51.lib there is no dll output. Could this be because  
I compiled lua51.dll/.lib with Visual Studio? I'll try compiling Lua with  
dmc.

I fixed the problem by using implib on lua51.dll to generate a new .lib  
file. The DLL isn't working properly, but this is likely a different  
issue; so I'll open a new thread for that if necessary.
