Unable to copy SDL2.framework into /Library/Frameworks directory

[gfuggetta]

Dear Lazarus team,

I am very new in the use MacOs (I have started using Big Sur three days ago).

I have the Lazarus source code of my software which currently compiles for Windows and Linux.

To compile my software for MacOs I would need to copy the following four frameworks into the System frameworks folder.

Library/Frameworks/SDL2.framework

Library/Frameworks/SDL2_mixer.framework

Library/Frameworks/SDL2_ttf.framework

Library/Frameworks/SDL2_image.framework


So,I downloaded the four corresponding versions of .dmg MacOS installer files. When I opened them, I found the four directories listed above (e.g. SDL_image.framework, etc..). Unfortunately, when I tried to copy one by one the the four "framework" to the place where all other SDL frameworks are stored (/Library/Frameworks directory), the access was denied. 

Consequently, the Lazzaus Mac Os compiler is writing this message:
Error: Id:framework not found SDL2.

I am the only user on this machine, so I should have the rights as administrator.



Is there an alternative simple way I should use to be able to copy these four frameworks to the framework directory perhaps using the terminal (e.g. sudo, etc...)?

Please note: I am a beginner in using Mac Os. So it would be nice if you could write in simple words the procedure to solve the issue. Many thanks

Best wishes

How did you install them in Windows and Linux...
Should be the same way

Any app-specific frameworks should be included in your app bundle.
ie. project1.app/Contents/Frameworks/SDL2.framework

and then use the command line utility install_name_tool thus:

Code: [Select]

cd project1.app/Contents/MacOS
install_name_tool -add_rpath "@executable_path/../Frameworks/." project1
Full details in the Wiki at macOS Dynamic Libraries.

Thank you very much,

I will try what you have written.

Library/Frameworks/SDL2_mixer.framework
Library/Frameworks/SDL2_ttf.framework

OK, to compile the application you need to either copy the SDL2 frameworks to /Library/Frameworks or tell the linker where to find them.

To copy them to /Library/Frameworks you will need to open am Applications > Utilities > Terminal, change to the directory in which the frameworks are located and copy them to the destination using eg:

 sudo rsync -rv SDL2* /Library/Frameworks

Alternatively, to tell the linker where to find them, in the Lazarus IDE go to Project > Project Options > Compiler Options > Compilation and Linking and there you will have to check the option "Pass options to linker with -k, delimiter is space" and enter the following:

 -F/path/to/SDL2_frameworks

(The trick here is NOT to enter -k at all as Lazarus does this automatically).

Of course you will probably also need the {$linkframework whatever} directive(s) in your Pascal unit(s).

When it comes to distributing your application, you will need to include the frameworks as previously indicated in the application bundle.
