Don't have a Makefile to show, but I've done the following in the past when I have dub dependencies but need to use my own build system:

- Create a subdirectory containing a dummy empty dub project (containing
  nothing but an empty main()), whose sole purpose is to declare dub
  dependencies that I need.
- Run dub to retrieve and compile said dependencies, with --vverbose so
  that shows the actual compile commands (for extracting the pathnames
  of the compiled artifacts).
- Copy-n-paste the compiled objects paths into my build system as object
  files / libraries to link against.

In theory, the second step above can be automatically parsed to extract the needed paths, or even recompile after altering the command-line options, but I never got that far because I've since shelved the project (for reasons unrelated to dub).

We have a few build formats that dub can generate for you automatically:

```
visuald - VisualD project files
sublimetext - SublimeText project file
cmake - CMake build scripts
build - Builds the package directly
```

Unfortunately none of them are make, it would be nice to have that if you are looking to contribute!

Wait, dub can generate all those? I only knew about visuald

build is just dub and doesn't emit any project files.

But yes, it has two others (although idk how much they get used, or how complete).

If cmake works, then cmake could generate a normal makefile :)

Kind regards,

Using the first two all the time.
IIRC VisualD projects respect --combined
