Hello everyone,

I started to learn basics of SQLite last week for my small side project & I was quite impressed with its form factor. Long story short, I decided to call it directly from D Language after seeing "This one simple trick allows D programmer use llama.cpp, rust programmers hate him!" [1].

It simply worked with amalgamated sqlite files! What I did was to create a single line of code include file and import it to my D Language application, which is a port of the reference C Application in SQLite references [2]. I also compiled the static library using gcc & linked it together with the D Language binaries. Guess what? It worked.

I am still scratching my head about how I did this and if I made any mistakes because it feels quite un-natural to be able to link together an output compiled by gcc with dmd. If someone could please explain how & why this works, I'd greatly appreciate it!

I wrote a small blog post on how to replicate my work & source files are on my github if anyone's interested in this.

Best wishes,
Selim

Quite natural, actually.

D has been ABI compatible with C from the beginning. It uses the same object file formats and the same linkers that C compilers use. The earliest D users, at a time when there were no D libraries, could write their programs in D and incorporate the existing C ecosystem. A lot of the modules people shared back then were just bindings to C libraries.

Wow, I started using D only five years ago & genuinely didn't know this. Amazing. Thank you.
