What is the ldd command?
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. If some shared library is missing for any program, that program won’t come up.
How do I find my ldd library?
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 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.
What does Ldconfig mean?

What is vDSO used for?

How do I disable vDSO?
In Ubuntu 16.04 vDSO can be disabled system-wide by adding the kernel parameter vdso=0 in /etc/default/grub under the parameter: GRUB_CMDLINE_LINUX_DEFAULT . IMPORTANT: Parameter GRUB_CMDLINE_LINUX_DEFAULT might be overwriten by other configuration files in /etc/default/grub.

Why is Lego Digital Designer not working?

Is Stud io better than LDD?
In our opinion, when comparing these two softwares, BrickHello put it best: “LDD is a 2 storey building that is easy to climb up and the view is just okay, while Stud.io is a 50 storey building that takes a while to climb, but is takes time to reach the top but you eventually see the spectacular view”.
What is Ldconfig Ubuntu?
