00:00:05,330 --> 00:00:06,010
Hello everyone.

2
00:00:06,360 --> 00:00:10,299
In this video, I'll be installing
the compiler and the development

3
00:00:10,300 --> 00:00:15,100
tool chain that we're going to use
on the Mac to develop C++ programs.

4
00:00:15,450 --> 00:00:18,450
Now there's a couple of things that can go
on here, we can install them from scratch,

5
00:00:18,450 --> 00:00:19,760
which is what I'm going to do here.

6
00:00:20,150 --> 00:00:23,180
They may be already installed on
your system, in which case you're

7
00:00:23,180 --> 00:00:25,900
going to get a message saying that
they're already installed and I'll

8
00:00:25,930 --> 00:00:27,400
walk you through both those scenarios.

9
00:00:27,770 --> 00:00:29,319
So what I want to do here is

10
00:00:29,320 --> 00:00:32,500
I want to open up a Terminal session,
so you can just press command

11
00:00:32,500 --> 00:00:36,970
space bar and type in terminal, and
that'll open up a terminal shell.

12
00:00:37,380 --> 00:00:40,120
And I'm just going to hit command plus
a few times just to make it a little

13
00:00:40,130 --> 00:00:42,650
bigger, make it easier to see, all right?

14
00:00:42,650 --> 00:00:47,129
So at this point, we're going to type
in sudo, that's sudo followed by a

15
00:00:47,130 --> 00:00:54,130
space and then xcode dash select dash
space again and then dash dash Install.

16
00:00:54,799 --> 00:00:59,300
So again, sudo space, xcode
dash select space dash dash

17
00:00:59,300 --> 00:01:00,840
install and I'll press enter.

18
00:01:01,650 --> 00:01:04,319
And it's going to ask you for your
password, so just type in your password.

19
00:01:04,780 --> 00:01:08,289
Let me try that again, all right.

20
00:01:08,289 --> 00:01:11,320
So now, if the tools have not been
installed, you're going to get a pop

21
00:01:11,320 --> 00:01:14,490
up like this that says, we're going to
install the tools and that's exactly what

22
00:01:14,490 --> 00:01:16,250
I want to do, I'm going to click install.

23
00:01:16,540 --> 00:01:19,590
If the tools are already installed,
then you're going to get a message

24
00:01:19,590 --> 00:01:21,990
in the terminal saying that
they're already installed nothing,

25
00:01:22,000 --> 00:01:22,939
you don't need to do anything.

26
00:01:23,230 --> 00:01:26,670
Just consider the tools installed
and move on to the next video.

27
00:01:26,990 --> 00:01:29,080
So, I'm going to select install.

28
00:01:30,150 --> 00:01:33,550
I'm going to scroll through my
license agreement and agree to it.

29
00:01:35,540 --> 00:01:37,580
And I was just going to go
off and install the software.

30
00:01:37,580 --> 00:01:40,539
This process could take a couple of
minutes, it could take a lot longer.

31
00:01:40,860 --> 00:01:44,929
It really depends on your computer,
as well as your Internet connection.

32
00:01:45,420 --> 00:01:49,009
So, I'm going to pause the video here
and I'll come back as soon as it's done.

33
00:01:51,539 --> 00:01:52,730
Okay, so we're done.

34
00:01:52,950 --> 00:01:56,910
The process took just over ten
minutes on my machine, just so you

35
00:01:56,920 --> 00:01:58,470
have an idea of how long it can take.

36
00:01:58,789 --> 00:02:01,909
Again, it might take longer
or it might be a lot faster,

37
00:02:02,090 --> 00:02:03,230
depending on a lot of things.

38
00:02:03,469 --> 00:02:04,289
So we're done.

39
00:02:04,760 --> 00:02:07,649
I'm going to click done, now I'm going to
close this window and I'm going to open

40
00:02:07,650 --> 00:02:09,530
it again just, so we get a fresh one.

41
00:02:09,550 --> 00:02:14,500
Again, I'm going to press command space,
and then I'm going to type terminal and

42
00:02:14,510 --> 00:02:15,800
make this thing a little bit bigger.

43
00:02:16,410 --> 00:02:21,520
And now, I want to type g++
space dash dash version.

44
00:02:22,309 --> 00:02:26,840
And when I press enter, I get the
information about the compiler that we'll

45
00:02:26,840 --> 00:02:28,530
be using, which is this guy right here.

46
00:02:29,420 --> 00:02:32,840
If you went through the installation,
just like I did, this should pop up.

47
00:02:32,960 --> 00:02:35,420
If you started the installation
and it said that the command line

48
00:02:35,420 --> 00:02:36,959
tools were already installed.

49
00:02:37,219 --> 00:02:41,400
When you type g++ dash dash version,
you should get something very similar.

50
00:02:41,609 --> 00:02:44,090
Obviously the versions are going
to be different depending on when

51
00:02:44,090 --> 00:02:46,810
you install this and what the
latest version and so forth is.

52
00:02:46,830 --> 00:02:51,109
But if we're at this point, we've got our
compiler installed and we're good to go.

53
00:02:51,690 --> 00:02:55,350
In the next video, we'll install
CodeLite on Mac and then we'll

54
00:02:55,350 --> 00:02:56,779
be good to go to start coding.

55
00:02:57,530 --> 00:02:58,549
I'll see you in the next video.
