Downloading the zip file referenced earlier and using a simple main.c
$ clang -x c -o main.o -c main.c
$ clang main.o -o main
$ otool -L main
main:
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 1213.0.0)
adding the framework right from the unzipped zip and then otool’ing it
$ clang main.o -F ~/Downloads/Mac-Framework-master -framework Paddle -o
main
$ otool -L main
main:
@executable_path/../Frameworks/Paddle.framework/Versions/A/Paddle
(compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 1213.0.0)
That’s that @executable_path from the library, using otool -D on it ...
$ otool -D ~/Downloads/Mac-Framework-master/Paddle.framework/Paddle
/Users/rols/Downloads/Mac-Framework-master/Paddle.framework/Paddle:
@executable_path/../Frameworks/Paddle.framework/Versions/A/Paddle
now update it and check it again
$ install_name_tool -id @rpath/bananas/are/tasty
~/Downloads/Mac-Framework-master/Paddle.framework/Paddle
$ otool -D ~/Downloads/Mac-Framework-master/Paddle.framework/Paddle
/Users/rols/Downloads/Mac-Framework-master/Paddle.framework/Paddle:
@rpath/bananas/are/tasty
and re-link main and then otool it again
$ clang main.o -F ~/Downloads/Mac-Framework-master -framework Paddle -o
main
$ otool -L main
main:
@rpath/bananas/are/tasty (compatibility version 1.0.0, current
version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 1213.0.0)
That’s where it comes from - that’s how you can change it. Don’t know what
you’re seeing.
