You can simply run this command :
$ ldconfig -v | grep 'your_library_name'
The output will tell whether your library is installed or not. You can use
wildcards to grep the library in case you dont know the exact name of
library.
one tip :
In case you are using Debian based distro and you already installed the
required package which contains the library required for your application to
run using 'apt-get install' command. You can simply find the installed path
of all the files contained in that package by running-
$dpkg -L pkg_name
It will list absolute path of all the files installed by that pkg.

Re: Checking Installed library
Hi Rishi, I am using this particular line: > > AC_CHECK_LIB(xml2,xmlParseFile,,AC_MSG_ERROR(oops! no function xmlParseFile > function in xml?!?),) in my configure.in for autoconf > It should work fine for you in most of the cases. But I really doubt if this the best possible way to achieve what you want. But I really wonder why autoconf doesn't adds a check for libraries that you use in you sources. Neways, I would suggest you that you post the exact steps that you are trying to provide others with a better picture of what you goal is and how you are trying to achieve it. > The use of macro is > > AC_CHECK_LIB : Checks whether a function exists in the given library > (library names without the leading lib, e.g., for libxml, use just xml here) > > It seems that it is not path dependant.

Currently I am using a macro which checks wether a function is present in the mentioned library. like printf can be checked in libc I used a function "xmlParsefile" and "libxml2" library and this works fine. The logic behind this is that when the function is present in the library then the library is also present on the system (is it correct ??) -- Regards, Rishi B.

Re: Checking Installed library
i think u should refer to the autoconfigure and check how they do
these things, all the open source package use configuration file to
check the library dependence.

Checking Installed library
Hello All,
I want to check whether a particular library is installed or not using a
shell command.
I want to write a install script which will first check whether the
libraries required to compile my code are available on the system or not.
something like #check_library libxml2 (on shell)
or
retval = check_library("libxml2"); will do.
