When compiling test.d, the compiler needs to find the function signatures/struct declarations and so on that rely on the other modules. To do that, you have to include the other modules for the compiler to read. You can do that by: dmd test.d math.a -Isrc ./test When you are using -I flag, the included files are NOT compiled, but can be thought of as being used as headers in C/C++. One other note, note that you should include 'src' folder, and the files would be found properly using the module - filesystem mapping.

The -I flag comes closest to solving the issue. Ideally I would like to be able to alias my src folder to dragonfly in the module system while compiling smaller libs. But if that's not possible then adding a dragonfly folder to src and using -Isrc to point the compiler towards the right folders will work just fine. Off to play with libraries. :)
Building library
Hey I've just started getting into D and so far I'm just messing around with it in a small math library. However I've run into an issue while trying to build a library and linking it with my main file. My current file and module layout is test.d src/math/vector.d - module dragonfly.math.vector src/math/quaternion.d - module dragonfly.math.quaternion Compiling with $ dmd test.d src/math/vector.d src/math/quaternion.d ./test works perfectly and runs the way I would expect. I then tried to compile a library as described http://ddili.org/ders/d.en/modules.html, so basically $ dmd src/math/vector.d src/math/quaternion.d -lib -ofmath -w $ dmd math.a test.d ./test But this fails with the following error test.d(5): Error: module vector is in file 'dragonfly/math/vector.d' which cannot be read I realize I placed my files in a 'src' dir instead of 'dragonfly', but shouldn't explicitly declaring the module name in vector.d and quaternion.d fix that?

When you do `dmd math.a test.d`, you don't give dmd a file that contains the module dragonfly.math.vector. math.a does contain the object code, but it misses stuff like function signatures. For this information dmd needs source files for each module. If you change the directory structure to mirror the module structure, dmd finds the necessary files itself. Or you can specify all source files yourself on the command line, along with the library file. Since the library file already contains the object code, you can also give dmd files that omit the function bodies. You may know this concept from C: header files (.h). In D it's interface files (.di).
