The shell path for a user in macOS or OSX is a set of locations in the filing system whereby the user has permissions to use certain applications, commands and programs without the need to specify the full path to that command or program in the Terminal. This will work in macOS Mojave, Sierra and all older OSX operating systems; El Capitan, Yosemite, Mavericks and Lion.

Linux: LDLIBRARYPATH; Windows: PATH; TOMLAB for Mac OS X does not currently require the corresponding variable to be set, due to all binaries having hard-coded paths to their respective dependencies. This, on the other hand, demands that binary files in the TOMLAB directory are not moved from their locations. Mac OS X 10.8 (Mountain Lion) installation with brew. Gerris installation on Mountain Lion is pretty straightforward using brew (using a different package manager, e.g. Macports, should not be a problem - see the Wiki's history).

So instead of running something like this, with a path to the command:

You can just type the command, regardless of where you are in the filing system:

Your shell path is a bunch of absolute paths of the filing system separated by colons :

This will start installing LabVIEW Runtime.Method 4With the LabVIEW Professional Development System, use the Application Builder in a LabVIEW Project to create an installer file. Click on LabVIEW Runtime as highlighted below. Select the required Version and Bitness then Click the Install button.

You can find out whats in your path by launching Terminal in Applications/Utilities and entering:

And the result should be like this…

So this is stating that you can run Unix style applications or commands located in 5 default locations of a certain path in the filing system:

• /usr/bin
• /bin
• /usr/sbin
• /sbin
• /usr/local/bin

These directories are not visible by default in the filing system but you can make them visible.

Adding a Temporary Location

You can add extra locations to your path, in the mysql example above it’s location /usr/local/mysql/bin which is not in the default path, you can add it in Terminal like so:

So here I have copied my existing path and added the new location on the end. Test it by running echo $PATH again in the Terminal.

One of the disadvantages of this is that the new location will only be honored for that particular Terminal session, when a new Terminal window is launched it will have the original default path again.

Adding in a Permanent Location

To make the new pathstick permanently you need to create a .bash_profile file in your home directory and set the path there. This file control various Terminal environment preferences including the path.

Move into home directory

Create the .bash_profile file with a command line editor called nano

Add in the above line which declares the new location /usr/local/mysql/bin as well as the original path declared as $PATH.

Save the file in nano by clicking ‘control’ +’o’ and confirming the name of the file is .bash_profile by hitting return. And the ‘control’+’x’ to exit nano

So now when the Terminal is relaunched or a new window made and you check the the path by

You will get the new path at the front followed by the default path locations, all the time

Rearranging the default $PATH

If you needed to rearrange the paths in the default $PATH variable, you can just do that and leave off $PATH.

So lets say you want /use/local/bin at the beginning to take precedence you can add the default path like so inside .bash_profile

And then you can slot in other paths as required.

How to Load a Java Native/Shared Library (.jnilib)

There are several ways to make it possible for the Java runtime to find and load a native shared library (.jnilib) at runtime. I will list them briefly here, followed by examples with more explanation below.

Ubuntu Ld Library Path

1. Call System.load to load the .jnilib from an explicitly specified absolute path.
2. Copy the shared library to one of the paths already listed in java.library.path
3. Modify the LD_LIBRARY_PATH environment variable to include the directory where the shared library is located.
4. Specify the java.library.path on the command line by using the -D option.
5. Put the .jnilib in /Library/Java/Extensions/.

1. Call System.load to load the shared library from an explicitly specified absolute path.

This choice removes all uncertainty, but embeds a hard-coded path within your Java application. Example:

2. Copy the shared library to one of the paths already listed in java.library.path

To view the paths listed in java.library.path, run this Java code:

Note: The java.library.path is initialized from the LD_LIBRARY_PATH environment variable.

The loadLibrary method may be used when the directory containing the shared library is in java.library.path. To load 'libchilkat.jnilib', call System.loadLibrary('chilkat'), as shown below.

3. Modify the LD_LIBRARY_PATH environment variable to include the path where the Chilkat shared library is located.

Osx Ld_library_path

For Bourne Shell, K Shell or Bash, type:

For C Shell, type:

4. Specify the java.library.path on the command line by using the -D option.

For example:

Additional Notes:

From developer.apple.com: 'JNI libraries are named with the library name used in the System.loadLibrary() method of your Java code, prefixed by lib and suffixed with .jnilib. For example, System.loadLibrary('hello') loads the library named libhello.jnilib. Java HotSpot also recognizes .dylib as a valid JNI library format as of Mac OS X v10.5.'
