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.
With the release of Mac OS X Lion way back in 2011, Apple removed easy access to the user's Library folder. Although arguably well-intentioned, this change was frustrating for longtime Mac power. 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. 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. Jul 25, 2011 Inside your Home folder is a Library folder (/Library), accessible only to you, that's used to store your personal application-support files and, in some cases, data. The files and folders in.
- 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.
- Hammer out a sample program on your favorite editor (Vim) and name it
main.cor something.
- 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-Lflag provides the path to the library, and the-lflag provides the name of the library that you'd like to link.
- Run the executable
a.outfrom the command line.
This should produce the following output:

Greece defense td mac os. Inside your home folder is a Library folder—commonly written in Unix syntax as ~/Library, which means 'a folder named Library at the root level of your home folder.' This folder is accessible only to you, and it's used to store your personal settings, application-support files, and, in some cases, data.
The files and folders in ~/Library are generally meant to be left alone, but if you've been using OS X for a while, chances are you've delved inside. Perhaps you wanted to tweak something using a tip from Macworld, Mac OS X Hints, or elsewhere on the Web. Or maybe a developer asked you to delete a preference file, or grab a log file, while troubleshooting a program. Whatever the case may have been, up until Lion (OS X 10.7), you simply opened your Home folder to access the Library folder.
But after upgrading to Lion, OS X 10.8 Mountain Lion, OS X 10.9 Mavericks, and yes even OS X 10.10 Yosemite, the first time you tried accessing your personal Library folder, you likely found…well, you didn't find. The folder was gone.
The disappearing Library folder
At least, that's how it appears. But rest assured, regardless of your version of OS X, your personal Library folder is right where it's always been, at the root level of your Home folder. It's just that, starting in Lion, and continuing in Mountain Lion, Mavericks, and Yosemite, Apple has made the folder invisible.
The reason for this move is presumably that people unfamiliar with the inner workings of OS X often open ~/Library and start rooting around, moving and deleting files, only to later discover that programs don't work right, application settings are gone, or—worse—data is missing. This is the same reason Apple has always hidden the folders containing OS X's Unix underpinnings: /bin, /sbin, /usr, and the like.
While I understand Apple's motives here—I've had to troubleshoot more than a few Macs on which an inexperienced user has munged the contents of ~/Library—a user can have plenty of valid reasons for needing to access the personal Library folder. Factories of steel mac os. Luckily, as I mentioned, the folder is merely hidden, using a special file attribute called the hidden flag. You just need to know how to make the folder visible again.
The setting you need to know
If you're still running Lion or Mountain Lion, making the ~/Library folder requires a little bit of work. No lift no gift mac os. (I came up with—no joke—19 ways to view the folder in Lion and Mountain Lion.) But in Mavericks and Yosemite, Apple has made the task much more convenient, providing an easily accessible setting for toggling the visibility of your user-level Library folder. Here's how to use it:
Open your home folder (/Users/yourusername) in the Finder. Depending on your Finder settings, this may be as easy as simply opening a new Finder window. Otherwise, choose Home from the Finder's Go menu (Go > Home); or press Shift-Command-H.
Still in the Finder, choose View > Show View Options (or press Command-J).
Near the bottom of the resulting View-Options palette is a setting called Show Library Folder. Enable this option. Your Library folder is immediately visible.
Close the View-Options palette.
You can access this setting at any time to toggle the visibility of your personal Library folder. For example, Macworld senior contributor Joe Kissell has found that applying an OS X update can make the folder invisible, requiring you to manually make it visible again.

Now that the folder is visible, just remember to be careful—because, as I mentioned above, deleting or moving the wrong file(s) inside this folder could cause an application to misbehave, to lose its settings, or even to lose data.
