The compiler and my test-application compiled fine. I flashed my device but there I don't see anything. At the moment I can't debug with JTAG, so I'll have to fix that first before I can say more.

Well maybe ExportAll compiler feature should be suggested?
But please try this
unit Unit1;
{$mode objfpc}{$H+}
interface
procedure proc1; stdcall;
procedure proc2; stdcall;
implementation
procedure proc1; stdcall;
begin
writeln('hello');
end; exports proc1;
procedure proc2; stdcall;
begin
writeln('hello 2');
end; exports proc2;
end.
Notice how I put exports in several places...
It works on win32..
Try linux?
Now for your executable, load it like so:
program p;
{$mode objfpc}{$H+}
procedure proc1; stdcall; external 'd2.dll';
procedure proc2; stdcall; external 'd2.dll';
begin
writeln('First proc from lib..');
readln;
proc1;
readln;
writeln('Second proc from lib..');
proc2;
readln;
end.

It only partially works. Please see the bug report I mentioned earlier:

Does this just mean I have to compile my library with -B every time? If
that is the case, then I don't mind.
I prefer to have a more manageable unit structure at the cost of an
extra compiler option, than dealing with
lots of includes or a very large exports section.
Regards,
Torsten.

end.
I tried and it didn't seem to work, however perhaps it could be related
to that I'm trying to create a library for arm-linux on android.
I've been following the guides from
http://wiki.lazarus.freepascal.org/Custom_Drawn_Interface/Android which
i know probably is trying to
do something that's not possible.
Anyway, thanks to both of you for the help so far.
Regards,
Torsten.

Try adding EXPORT keyword after the stdcall.
I forgot to put that in there, that's what i used, but I figured it was
not needed so I deleted it before I sent my message. I thought export
keyword was not used for exports..

interesting, I tried BUILD ALL in lazarus ide and it works, but I also
tried not building all and using the EXPORT keyword along with EXPORTS
section, and that requires no build all. Whereas without the EXPORT
keyword it only works if you build all. This is on win32.
So the export keyword does something on win32?
You said that EXPORT keyword is for emx and os/2 ...
But maybe I should look into the compiler sources to see if it does
something else.. it seems to cause the dll to work without a build all..

.
.
It's intended to be supported under OS/2 and EMX indeed. However, the
compiler probably won't do much with EXPORT under EMX and OS/2 either
as of now (it doesn't work due to issues with the GNU linker
available for OS/2).
