digitalmars.D.learn - Packages and module import

reply Russel Winder <russel winder.org.uk> writes:
I had assumed that a directory of modules was a package. So for
example:

	A/a.d
	A/b.d

were two modules in package A. Especially given there is a module
statement at the beginning of each module:

A/a.d has  module A.a;
A/b.d has  module A.b;

Now A.b needs to access something from A.a. I had assumed that the
import should be fully qualified. So in A.b.d:

	import A.a: thing;

This all works when building the library.

Am I just missing something simple?

It is not especially, it is ONLY because of the module statement.

The directory layout is a convention so tools can find the module 
file, but only the module declaration line in the code itself 
defines the authoritative name.

Odds are, linux_dmx.d is missing the `module 
libdvbv5_d.linux_dmx;` line.

Any import statements and module statements need to use the same 
name. The layout in the file system is secondary to this.

You are right. I was certain I had correct module statements in all the
modules, but I hadn't.

To my amateur eyes, first command-line build looks like a linking 
of object files into a .so. The second command-line build looks 
like compilation is taking place. Seems like the command-line 
used to compile the library is missing.

Not sure if this will help, but are you aware that DStep can add a 
package to the module declaration using "--package"?

Cool :). I recommend having a look at the changelog and the usage 
information (--help).
