How to use 3rd party framework depends from dylib for IOS in Delphi Firemonkey

问题

I'm using 3rd-party SDK, presented as libXXX.a, that needs

• libstdc++.dylib
• libz.dylib

15/05/2017 ANSWER. Finally I have found a time to write down my solution. If your 3rd party SDK depends from some dynamic libraries, do this:

1. For example dynamic library is called as "libSuperLibrary.dylib".
2. For example 3rd party SDK is called as "SuperFramework.framework".
3. Go to "Project - Options - Delphi Compilier - Framework Search Path"
4. Fill the field by path to your framework like "C:\path\to\my\frameworks\"
5. Go to "Project - Options - Linking - Options passed to the LD linked"
6. Fill the field by string "-ObjC -framework SuperFramework -lSuperLibrary
7. Compile

回答1:

IOS does not allow dynamic libraries. When building with XCode it automatically links the needed static libraries, but only in the final app, not if you build a static library. Instead you can tell Delphi to handle the dependencies.

In the pascal header file for libXXX.a (where you import the functions to Delphi) add dependency like this:

function  MyFunction; cdecl; external libXXX.a name 'myfunction' dependency 'stdc++'

I have used it my self with 'c++' (which corresponds to 'libc++.dylib') and 'stdc++' (corresponds to 'libstdc++.dylib'), but you will have to try your self if it works with the z library.
