This morning I installed, compiled, and ran a simple example program using the GNU Scientific Library. This took me a while to figure out, so I’ll share the process here. I am assuming that the reader, like the author, has only vague familiarity with C.

• Install Homebrew, their site has a line of code you can run from the command line.
• Install Xcode from the Apple Applications menu.
• Install GSL, the GNU Scientific Library, using Homebrew. This will install GSL at /usr/local/include.

Apr 19, 2021 Apple hides the Library folder by setting a file system flag associated with the folder. You can toggle the visibility flag for any folder on your Mac. Apple chose to set the Library folder's visibility flag to the off state by default. Here's how to change it. In OS X 10.7 Lion and OS X 10.8 Mountain Lion, Apple has decided to hide the /Library folders. As most users will not require access to these during their day-to-day activities, this makes sense. Hiding the /Library folders means there is less risk of an accidental deletion or change being made to a critical file. The user Library folder is hidden by default in macOS. Use one of the following methods to make the user Library content visible. Method 1 In the Finder, hold down the Option key when using the Go menu.

• Hammer out a sample program on your favorite editor (Vim) and name it main.c or something.

1. While Apple's previous iPod media players used a minimal operating system, the iPhone used an operating system based on Mac OS X, which would later be called 'iPhone OS' and then iOS. The simultaneous release of two operating systems based on the same frameworks placed tension on Apple, which cited the iPhone as forcing it to delay Mac OS X 10.
2. /Library/Containers contain the home directories of sandboxed apps. Sandboxed apps are for example the apps you download from the Mac App Store. Sandboxing means that they are 'isolated' from the rest of the system, so that a single app is not able to do unjust harm to other parts of the system.

• Compile the code. This should produce an object file in your working directory called main.o.

• Link the object file to produce an executable, a.out. Here, the -L flag provides the path to the library, and the -l flag provides the name of the library that you’d like to link.

• Run the executable a.out from the command line.

This should produce the following output:
