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.
Why do I need to run Ldconfig?
It checks the header and file names of the libraries it encounters when determining which versions should have their links updated; it ignores symbolic links when scanning for libraries. Ldconfig should normally be run by the super-user as it may require write permission on some root owned directories and files.
How do I run Ldconfig?
while ldconfig is inside /sbin which is outside the PATH, so you have then either to run the commands by absolute path like /sbin/ldconfig or correct your path.
What is Ld so Conf D?
so. conf. d and libraries from the trusted directories, /lib and /usr/lib, and any others supplied on the command line. The ldconfig command creates the necessary links and cache to recently used shared libraries in /etc/ld.
How do you run make install?
Your general installation procedure will therefore be:
- Read the README file and other applicable docs.
- Run xmkmf -a, or the INSTALL or configure script.
- Check the Makefile .
- If necessary, run make clean, make Makefiles, make includes, and make depend.
- Run make.
- Check file permissions.
- If necessary, run make install.
What file is read by the program Ldconfig?
The program ldconfig(8) by default reads in the file /etc/ld. so. conf, sets up the appropriate symbolic links in the dynamic link directories (so they’ll follow the standard conventions), and then writes a cache to /etc/ld. so.
What package contains Ldconfig?

Which of the following is a configuration file that the Ldconfig file uses when checking for shared libraries available?
The main configuration file for the ldconfig command is the /etc/ld. so. conf file. This configuration file contains shared library configurations or provides a link to the other shared library configurations which are located under the “/etc/ld.
How do I install Linux installer?
Create a Self-Extracting Installer in Linux
- Install makeself cd /opt/app wget https://megastep.org/makeself/makeself-2.1.5.run chmod 755 makeself-2.1.5.run ./makeself-2.1.5.run cd makeself-2.1.5 cp *.sh /usr/bin.
- Example.
Do you need to run make before make install?
When make is called with no parameters, it runs the first target, which usually simply compiles the project. make install maps to the install target, which usually does nothing more than copy binaries into their destinations.
Where is Ldconfig located?
Rebuild Cache ldconfig is located at /etc/ld.
What means make install?
When you do “make install”, the make program takes the binaries from the previous step and copies them into some appropriate locations so that they can be accessed. Unlike on Windows, installation just requires copying some libraries and executables and there is no registry requirement as such.
What is ldldconfig in Linux?
ldconfig is a program that is used to maintain the shared library cache. This cache is typically stored in the file /etc/ld.so.cache and is used by the system to map a shared library name to the location of the corresponding shared library file.
Why doesn’t ldconfig have a link to the library folder?
There’s no point in having that link unless you also have all the other development files (headers etc) for the library, so there’s no point in ldconfig automatically creating it.
How does the ldconfig cache work?
The cache is used by the run-time linker, ld.so or ld-linux.so. ldconfig checks the header and filenames of the libraries it encounters when determining which versions should have their links updated. ldconfig will attempt to deduce the type of ELF libs (ie. libc5 or libc6/glibc) based on what C libs, if any, the library was linked against.
How do I find a specific library in Linux?
/etc/ld.so.conf. File containing a list of colon, space, tab, newline, or comma-separated directories in which to search for libraries. /etc/ld.so.cache. File containing an ordered list of libraries found in the directories specified in /etc/ld.so.conf.
