Building (and including libraries) without dub
Building simple programs without dub is easy, just pass a list of .d source files to `dmd` or `ldc2`. What if I want to include a 3rd party library? Surely before dub existed, people were incorporating other libraries in their projects. I want to learn how this works from first principles. I've been working with dynamic/interpreted languages for too long, I forgot what it's like to build native programs without a dependency manager. Any help would be appreciated!

If you use Linux then: ``` dmd -L/path/to/lib -llibrarynamewithoutlibprefix ``` or example ``` dmd myapp.d -L../otherproject/lib -lcool ``` line above compiles `myapp.d` file and links it with library `libcool` that is place in directory `../otherproject/lib`

So if I may make a guess, when you include a dependency in a dub project, what it ends up doing is compiling the dependency separately into a lib file then statically link the lib with your project?

What if I want to include a 3rd party library? It is also easy, just pass the list of its d source files to the compiler as well. Quite trivial, really.

Note that yesterday I pushed a PR to dmd that allows you to import 3rd party libraries without having to list all their d source files on the command line (https://github.com/dlang/dmd/pull/7099). So long as the compiler knows where to find them (using -I), if you specify -ci (compile imports) it will automatically treat all unknown imports as if they were specified on the command line.

sometimes pragma("lib", ...) very usefull (if i understand you
correctly)
