Step 4 -- Set Run-time Library Path

At run-time, you need to tell the system where the API shared libraries reside.

On UNIX Systems

Set the library path as follows for the C and Bourne shells. In the commands shown, replace the terms envvar and pathspec with the appropriate values from the table below.

In the C shell, the command to set the library path is

```
setenv envvar pathspec
```

In the Bourne shell, use

envvar = pathspec:envvar
export envvar


Operating System	envvar	pathspec
HP-UX	`SHLIB_PATH`	`$MATLAB/bin/hpux`
Linux	LD_LIBRARY_PATH	`$MATLAB/bin/glnx86`
64-bit Linux	LD_LIBRARY_PATH	`$MATLAB/bin/glnxa64`
Solaris	LD_LIBRARY_PATH	`$MATLAB/bin/sol2`
MacIntosh	`DYLD_LIBRARY_PATH`	`$MATLAB/bin/mac:`$MATLAB/sys/os/mac

Here is an example for a Solaris system for the C shell:

setenv LD_LIBRARY_PATH $MATLAB/bin/sol2

and for the Bourne shell:

LD_LIBRARY_PATH=$MATLAB/bin/sol2:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH

You can place these commands in a startup script such as ~/.cshrc for C shell or ~/.profile for Bourne shell.

On Windows Systems

Set the Path environment variable to the path string returned by MATLAB in response to the following expression:

```
[matlabroot 'bin\win32']
```

To set an environment variable in Windows, click the Start button in the lower left corner of your desktop, point with the cursor to Settings and then Control Panel, and then click on System. Windows opens the System Properties dialog box. Click the Advanced tab, and then the Environment Variables button.

In the System variables panel, scroll down until you find the Path variable. Click on this variable to highlight it, and then click the Edit button to open the Edit System Variable dialog. At the end of the path string, enter a semicolon and then the path string returned by evaluating the expression shown above in MATLAB. Click the OK button in the Edit System Variable dialog box, and all remaining dialogs.
