00:00:05,050 --> 00:00:10,000
In this video, we'll go over the steps necessary to install the command line tools, which includes

2
00:00:10,000 --> 00:00:13,390
the C++ compiler on the MAC OS ten platform.

3
00:00:14,110 --> 00:00:16,430
In order to do this, we need to have a terminal window.

4
00:00:16,450 --> 00:00:22,630
So let's go over to Spotlight, search and type in terminal and we'll get a terminal window running.

5
00:00:22,750 --> 00:00:28,990
At this point, we want to type X Code Dash, select dash, dash install.

6
00:00:31,690 --> 00:00:32,680
And press enter.

7
00:00:33,850 --> 00:00:39,790
If you get a dialog box that pops up as I do, that means that the command line tools and the compiler

8
00:00:39,820 --> 00:00:41,620
are not currently installed.

9
00:00:42,250 --> 00:00:45,820
If you get a message saying that they are currently installed, then you're done.

10
00:00:45,820 --> 00:00:49,000
You can move on to installing the integrated development environment.

11
00:00:49,840 --> 00:00:55,870
In this case, I have the choice of installing the full Xcode integrated development environment or

12
00:00:55,870 --> 00:00:57,970
simply install the command line tools.

13
00:00:58,030 --> 00:01:01,990
I'm only going to install the command line tools, which again includes the compiler.

14
00:01:01,990 --> 00:01:03,460
So I'll select install.

15
00:01:05,019 --> 00:01:06,880
I'll agree to the license agreement.

16
00:01:10,270 --> 00:01:12,610
And the software will be downloaded and installed.

17
00:01:12,610 --> 00:01:14,140
It's a pretty quick process.

18
00:01:17,470 --> 00:01:22,090
After a few minutes, you'll see a message saying the software was installed and the installation is

19
00:01:22,090 --> 00:01:22,630
complete.

20
00:01:22,660 --> 00:01:31,540
You can test out the installation by simply typing G plus plus dash dash version at the terminal and

21
00:01:31,540 --> 00:01:36,250
you'll see the version number of the C++ compiler, which means it's all set and good to go.

22
00:01:36,370 --> 00:01:41,130
At this point, you'll keep the command line tools up to date through the App Store so you could select

23
00:01:41,140 --> 00:01:41,950
App Store.

24
00:01:44,180 --> 00:01:49,160
Updates and you can see your command line tool updates will appear here.

25
00:01:49,190 --> 00:01:52,610
Right now I've got no updates available because I just installed the latest.

26
00:01:53,300 --> 00:01:53,860
That's it.

27
00:01:53,870 --> 00:01:55,340
We've installed the command line tools.

28
00:01:55,340 --> 00:01:57,930
Our compilers are all set up and we're good to go.

29
00:01:57,950 --> 00:02:01,070
The next step is to install the integrated development environment.
