1
00:00:00,000 --> 00:00:02,583
(bright music)

2
00:00:05,070 --> 00:00:05,903
Frank: In this video,

3
00:00:05,903 --> 00:00:07,410
we'll go over the steps necessary

4
00:00:07,410 --> 00:00:09,360
to install the command line tools,

5
00:00:09,360 --> 00:00:11,670
which includes the C plus plus compiler

6
00:00:11,670 --> 00:00:14,160
on the Mac OS 10 platform.

7
00:00:14,160 --> 00:00:16,560
In order to do this, we need to have a terminal window

8
00:00:16,560 --> 00:00:19,410
so let's go over to Spotlight search and type in terminal

9
00:00:20,970 --> 00:00:22,800
and we'll get a terminal window running.

10
00:00:22,800 --> 00:00:27,420
At this point, we want to type X code dash select

11
00:00:27,420 --> 00:00:28,870
dash dash install

12
00:00:31,740 --> 00:00:32,583
and press enter.

13
00:00:33,930 --> 00:00:36,960
If you get a dialogue box that pops up as I do,

14
00:00:36,960 --> 00:00:38,820
that means that the command line tools

15
00:00:38,820 --> 00:00:42,360
and the compiler are not currently installed.

16
00:00:42,360 --> 00:00:43,620
If you get a message saying

17
00:00:43,620 --> 00:00:45,840
that they are currently installed, then you're done.

18
00:00:45,840 --> 00:00:47,220
You can move on to installing

19
00:00:47,220 --> 00:00:49,980
the integrated development environment.

20
00:00:49,980 --> 00:00:52,440
In this case, I have the choice of installing

21
00:00:52,440 --> 00:00:55,590
the full X code integrated development environment

22
00:00:55,590 --> 00:00:58,170
or simply install the command line tools.

23
00:00:58,170 --> 00:01:00,330
I'm only going to install the command line tools

24
00:01:00,330 --> 00:01:02,070
which again includes the compiler,

25
00:01:02,070 --> 00:01:03,423
so I'll select install.

26
00:01:05,069 --> 00:01:06,870
I'll agree to the license agreement,

27
00:01:10,320 --> 00:01:12,600
and the software will be downloaded and installed.

28
00:01:12,600 --> 00:01:14,253
It's a pretty quick process.

29
00:01:17,460 --> 00:01:19,710
After a few minutes, you'll see a message saying

30
00:01:19,710 --> 00:01:21,210
the software was installed,

31
00:01:21,210 --> 00:01:22,800
and the installation is complete.

32
00:01:22,800 --> 00:01:25,800
You can test out the installation by simply typing

33
00:01:25,800 --> 00:01:30,213
G plus plus dash dash version at the terminal,

34
00:01:31,410 --> 00:01:32,640
and you'll see the version number

35
00:01:32,640 --> 00:01:34,260
of the C plus plus compiler

36
00:01:34,260 --> 00:01:36,420
which means it's all set and good to go.

37
00:01:36,420 --> 00:01:39,180
At this point, you'll keep the command line tools up to date

38
00:01:39,180 --> 00:01:40,320
through the app store,

39
00:01:40,320 --> 00:01:41,913
so you could select app store,

40
00:01:44,190 --> 00:01:45,123
updates,

41
00:01:46,020 --> 00:01:48,240
and you can see your command line tool updates

42
00:01:48,240 --> 00:01:49,320
will appear here.

43
00:01:49,320 --> 00:01:50,513
Right now I've got no updates available

44
00:01:50,513 --> 00:01:53,370
because I just installed the latest.

45
00:01:53,370 --> 00:01:54,203
That's it.

46
00:01:54,203 --> 00:01:55,320
We've installed the command line tools,

47
00:01:55,320 --> 00:01:56,970
our compilers are all set up,

48
00:01:56,970 --> 00:01:57,990
and we're good to go.

49
00:01:57,990 --> 00:01:59,340
The next step is to install

50
00:01:59,340 --> 00:02:01,290
the integrated development environment.
