Hi,

My understanding is, a lib file is a collection of multiple obj files.

From a delphi app I want to call D coding without using a dll. Delphi does not know the concept of lib files but can link obj files.

Linking all single obj files of DRuntime, phobos and my library might be possible but I wonder whether there is a better way.

Therefore the question, if I have a d lib file which contains all the obj files of DRuntime, phobos and my custom code, is it possible to convert it to exactly 1 obj file?

Or must 1 obj file correspond to exactly 1 d module?

Kind regards
Andre

This is exact.

This should work if you pass the static library files to the linker. It is exactly its job to select what's used from the archive. So you would have to pass your stuff and optionally phobos2 as a static library (but this would also work if linking against phobos2.dll)

BTW I have an example here [1], but it's for FreePascal and under linux, and in the end i've decided to use dynamic library (but with static linking) [2]

The only thing I found so far is, Delphi does not support linking .lib files.
(Mac os 64 bit compiler though seems to support it).

I understand from you, that FreePascal is able to link .lib files.

Was my impression false and I can link .lib files with Delphi?

Kind regards
Andre

No (sorry for the false hope) I also find this (‑‑linker-option for iOS only).
Very surprising.

Looks like you would have to use a dll. Note that with static linking of the dll

  cdecl; external 'mydll';

You don't have to use a loader.
