I've spent the past couple of hours beating my head around this so I
thought I would see if I can get some help.
Considering the following directory structure:
a/
b/
compile.bat
c/
d/
my.dll
main.d
compile.bat:
dmd -run b/c/main.d -I../b -I../b/c/d/
pause
in main.d I have
pragma (lib, r"b/c/d/my.dll");
and I get Not a valid library file
Obviously there is, but is there something I'm missing?
I know I can put the dll in the system path and work on it from there,
but doing so ruins all portability I'm striving for, any pointers?

You need to create an import library (my.lib) and link to that. DMD
doesn't link directly to DLLs. In fact, most C and C++ compilers do not
do this on Windows, either. MingW is the only one I know of that accepts
DLLs on the command line in place of library archives.
