IIRC, you'll also need to export the curl symbols from the .exe for std.net.curl consumption, by adding `ldc\curl.exp` in the compiler command-line too.

Reminder of my requirements: - I am using d2sqlite3 and std.net.curl in a Windows 64 D program - Want to create a single exe file that I can distribute to other people without the need to distribute the related DLL's Progress to date: sqlite3: - I found a static compiled version of sqlite3.lib. So I am now able to link sqlite3 into my exe. curl: - No luck with curl yet. - As per comment from @pilger -- I got the sample DerelictSDL2 program working after adding "derelict-sdl2": "~>3.0.0-beta" to dub.json and "import derelict.sdl2.sdl;" to app.d - I see the exe is bigger, so I assume it it added to the relevant curl DLL -- but the separate Windows DLL file is still required to execute the exe. So it is not finding the imported DLL file! Is it possible to distribute an .exe file without the required libcurl DLL? Many Thanks

Many Thanks, Willem you can statically link libraries just like in other languages if you use dub it's as easy as this: ```json "sourceFiles-windows": [ "../_clibs/glfw3.lib", ] ``` if you use plain dmd, then it's simple ``` dmd main.d mylib.lib ``` You are correct. But that only works if you got the static libs. If you only have the dynamic libs you have to resort to embedding them (if you don't want to ship them separately).
