However, on multi-user research or development systems, you want each users to be able to have their own versions of libraries. Most Linux distributions allow this and have done so for many years.

Helped me as well — spt Yeah I agree with spt - I never knew that trick was possible.

Thank you Joachim Pileborg. I have reboot the system and now its path is set permanently. Toby Speight Anshul Anshul 1 1 gold badge 5 5 silver badges 18 18 bronze badges. Go to the home folder and edit. Execute this command sudo ldconfig. I do the following in Mint 15 through 17, also works on ubuntu server All users have the environment variable added.

When resolving shared object dependencies, the dynamic linker first inspects each dependency string to see if it contains a slash this can occur if a shared object pathname containing slashes was specified at link time. If a slash is found, then the dependency string is interpreted as a relative or absolute pathname, and the shared object is loaded using that pathname. If, however, the binary was linked with the -z nodeflib linker option, shared objects in the default paths are skipped.
Shared objects installed in hardware capability directories see below are preferred to other shared objects. If the binary was linked with the -z nodeflib linker option, this step is skipped.
This facilitates the creation of "turn-key" applications that do not need to be installed into special directories, but can instead be unpacked into any directory and still find their own shared objects. On some architectures, the Linux kernel doesn't provide a platform string to the dynamic linker. The objects in list are delimited by colons. This option is ignored when running in secure-execution mode see below.
The objects in list are delimited by colons or spaces. Secure-execution mode For security reasons, if the dynamic linker determines that a binary should be run in secure-execution mode, the effects of some environment variables are voided or modified, and furthermore those environment variables are stripped from the environment, so that the program does not even see the definitions.
Try if you can solve the problem by other means, e. So, what does it do? This can be used for testing new versions of a shared library against an already compiled application re-locating shared libraries, e.
Sounds very useful, where is the problem? In that way, a nasty person could get your application to load a version of a shared library that contains malicious code! Performance: The link loader has to search all the directories specified, until it finds the directory where the shared library resides — for ALL shared libraries the application is linked against!
If the path contains many directories, the number of failed calls will increase linearly, and you can tell that from the start-up time of the application. Improve this question.
