Re: [Help-gsl] unable to link and run a simple program

[Mohammad Akhlaghi]

Hi Vasu,

This is a dynamic linker problem. Linking with shared libraries is done 
every time you run a program. The compiler has indeed found the 
libraries and that is why your `a.out' has been created.

The dynamic linker looks into the `LD_LIBRARY_PATH' shell variable to 
find the libraries. So you have to put `/myinst/lib/' in this variable.

You can do this with a command like below. You can also put it in your 
`~/.bashrc' to be available at startup of your interactive bash sessions.

export LD_LIBRARY_PATH="/myinst/lib/:$LD_LIBRARY_PATH"

For more on custom installation paths, you can see the explanations in 
the link below.
