如何获取.so文件的依赖项列表？

Question

Let's say i'm having libFoo.so compiled for android (arm). I'm not sure what STL implementation it was linked to (there are options ). How can i get dependencies (as .so list) for it to understand what files i should provide and load using System.load(...)/loadLibrary(...) ?

You can use the objdump tool and filter out the relevant part. In this case, eg arm-linux-androideabi-objdump -p libFoo.so | grep NEEDED arm-linux-androideabi-objdump -p libFoo.so | grep NEEDED .

The ldd tool as suggested normally also does this, but it tries to actually find all the files that would be loaded, and it is not always available in cross-compilation environments.
