Hello,

I'm not able to do a static link of a dylib (with the latest lazarus + fpc build).

I'm using the following code:

function MyDyLibFunction: int; cdecl; external 'mylib.dylib';
begin
  MyDyLibFunction;
end;

If I use the LoadLibrary function to load the 'mylib.dylib' I'm getting a valid TLibHandle. Also the nm list MyDyLibFunction function (with _ prefix) in the library.

Can anyone give a pointer on how to make fpc statically link my shared library in mac osx?

Thanks,

You cannot statically link a dynamic library. I guess you want to dynamically link it, but at compile time rather than manually at runtime using LoadLibrary(). To do so, add {$linkib mylib} to the source. This will also work on other platforms.

Hi,
Thanks for the reply. That seems to work, but I think there is a bug in the FPC. When I do a {$linklib myfile.dylib} , it is not picking up the myfile.dylib, the compiler is looking for libmyfile.so . I had to rename the library from myfile.dylib to libmyfile.so .

Your library was simply named wrongly if it was called myfile.dylib. If you want the compiler and linker to find a dynamic library, its name must start with lib, so libmyfile.dylib (because to the linker you can only say -lmyfile, and then it automatically searches for libmyfile.dylib; maybe it also searches for libmyfile.so nowadays, I don't know).
