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.
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/<process-id>/maps.
Where is ldd on Linux?
Ldd is a Linux command line utility that is used in case a user wants to know the shared library dependencies of an executable or even that of a shared library. You might have noticed many files starting with lib* in /lib and /usr/lib directories of your Linux machine. These files are called libraries.
How do you use ldd?
How to use the ldd command? 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 ldd output mean?
DESCRIPTION top. ldd prints the shared objects (shared libraries) required by each program or shared object specified on the command line. An example of its use and output is the following: $ ldd /bin/ls linux-vdso. so. 1 (0x00007ffcc3563000) libselinux.
You need to use the ldconfig command to create, update, and remove the necessary links and cache (for use by the run-time linker, ld.so) to the most recent shared libraries found in the directories specified on the command line, in the file /etc/ld.
Do static libraries have dependencies?
If a static library’s code contains references to some shared library items, these references will become dependencies in the resulting executable. The same holds if you link a library instead of executable.
What does ldd do in Linux?
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.
What does Strace do in Linux?
strace is a diagnostic tool in Linux. It intercepts and records any syscalls made by a command. Additionally, it also records any Linux signal sent to the process.
What is ldd in chemistry?

What is Ldconfig in Linux?
ldconfig creates the necessary links and cache to the most recent shared libraries found in the directories specified on the command line, in the file /etc/ld. … ldconfig checks the header and filenames of the libraries it encounters when determining which versions should have their links updated.
What is glibc Linux?
What is glibc? The GNU C Library project provides the core libraries for the GNU system and GNU/Linux systems, as well as many other systems that use Linux as the kernel. These libraries provide critical APIs including ISO C11, POSIX. … The project was started circa 1988 and is more than 30 years old.
What is Linux vDSO So 1?
DESCRIPTION top. The “vDSO” (virtual dynamic shared object) is a small shared library that the kernel automatically maps into the address space of all user-space applications. Applications usually do not need to concern themselves with these details as the vDSO is most commonly called by the C library.
