Steps to find shared library dependency in Linux:
- Launch your preferred terminal application.
- Get absolute path of the program you want to check.
- Print shared object dependencies using ldd.
- Find dynamic library required by program using readelf.
- Read library requirement of running processes from /proc//maps.
How do I check .so dependencies in Linux?
- Linux. Linux uses the “ldd” command to show the libraries that are linked to an executable or another shared library:
- OS X. Use the “otool” command on OS X to show the libraries that are linked to an executable or another shared library:
- Windows. There is no command line tool for printing the dependencies on Windows.
How do you test for ldd?
Basic usage of ldd is fairly simple – just run the ‘ldd’ command along with an executable or shared object file name as input. So you can see all shared library dependencies have been produced in output.
How do I check program dependencies?
Simply run the program, click on File > Open and select the file that you want to check. A hierarchical tree diagram will be displayed on the program. A powerful feature found on Dependency Walker is the ability to detect all kinds of dependencies including the dynamic loading, delay loaded, injected and etc.
What does LDD?
ldd (List Dynamic Dependencies) is a *nix utility that prints the shared libraries required by each program or shared library specified on the command line. It was developed by Roland McGrath and Ulrich Drepper.
How to check shared library dependencies of an executable?
Check shared library dependencies of a program executable. To find out what libraries a particular executable depends on, you can use ldd command. This command invokes dynamic linker to find out library dependencies of an executable. > $ ldd /path/to/program.
How to check the dependencies of objdump binary?
It’s important to note that this doesn’t mean that all the symbols needed by the binary being passed to objdump will be present in the libraries, but it does at least show what libraries the loader will try to load when loading the binary. ldd -v prints the dependency tree under “Version information:’ section.
Is there any way to list library dependencies of a non-native binary?
The ldd is not a normal binutils utility, like strip or ar, that can be built alongside gcc for cross compiling, but instead, it is a cryptic shell script that apparently can only run on native platform. So, using the cross-target binutils tools, is there any way to get a list of the dynamically linked dependency for of a foreign binary?
How to inter-referencing shared libraries with dependencies?
The whole idea of inter-referencing shared libraries (i.e. creating APIs), is that the symbols in the deeper layers are hidden (think of peeling onions) and not used. .. i.e. don’t refer to symA in your main.cpp, but only to symB instead (and let symB to refer symA only).
