00:00:05,360 --> 00:00:09,360
Hello everyone.
In this video, I'll be installing the C++ compiler,

2
00:00:09,360 --> 00:00:13,660
along with the build tools that we'll need to build C++ programs

3
00:00:13,660 --> 00:00:14,660
on Linux.

4
00:00:15,060 --> 00:00:19,560
The distribution that I'm using is Ubuntu 2204, which is Jammy.

5
00:00:19,560 --> 00:00:22,250
There are a lot of different Linux distributions out there,

6
00:00:22,250 --> 00:00:24,250
so depending on which one you're on,

7
00:00:24,250 --> 00:00:28,250
you can check out the different options here for Ubuntu, Fedora, so forth.

8
00:00:28,250 --> 00:00:30,130
As I said, I'm on Ubuntu,

9
00:00:30,130 --> 00:00:33,730
so open up your favorite browser and head over to Codelite.org.

10
00:00:34,130 --> 00:00:37,430
And then once you get there, select Docs

11
00:00:39,430 --> 00:00:41,030
and getting started.

12
00:00:42,230 --> 00:00:45,920
And then right where it says prepare your environment, select Linux.

13
00:00:47,720 --> 00:00:51,710
And there's basically one command we're going to run, which is pretty straightforward.

14
00:00:51,710 --> 00:00:54,510
Once you get to the Linux section, there's a lot of information here, right?

15
00:00:54,510 --> 00:00:57,310
Depending on whether you want to install Rust and

16
00:00:57,310 --> 00:00:59,110
Python and Brew and so forth.

17
00:00:59,110 --> 00:01:01,810
I'm not going to do any of that, I'm just going to install the essentials,

18
00:01:01,810 --> 00:01:03,610
which gives us everything we need.

19
00:01:03,610 --> 00:01:07,610
And you can see this box right here that says Install the essentials.

20
00:01:07,910 --> 00:01:09,510
So what you can do is

21
00:01:09,510 --> 00:01:12,280
Hover over this box and click that little icon right

22
00:01:12,280 --> 00:01:14,980
 there that's going to copy this information to the clipboard,

23
00:01:14,980 --> 00:01:17,340
and that's what we're going to execute on a terminal now.

24
00:01:17,340 --> 00:01:19,940
I'm done with this for now, I'm just going to minimize it.

25
00:01:19,940 --> 00:01:21,200
I'm going to open up a terminal.

26
00:01:24,200 --> 00:01:26,560
All right, so there's my terminal.

27
00:01:26,560 --> 00:01:29,460
Now at this point, all I really want to do is,

28
00:01:29,460 --> 00:01:32,660
paste what I just copied into the terminal and execute it,

29
00:01:32,660 --> 00:01:33,960
It's as simple as that.

30
00:01:33,960 --> 00:01:36,960
So I'm going to right click right here, paste,

31
00:01:36,960 --> 00:01:39,560
click the right arrow key and press enter.

32
00:01:40,060 --> 00:01:42,060
It's going to ask you for your password.

33
00:01:43,860 --> 00:01:44,860
And that's it,

34
00:01:44,860 --> 00:01:48,160
some of these tools might already be installed depending on the

35
00:01:48,160 --> 00:01:50,420
 type of distribution you installed originally.

36
00:01:50,420 --> 00:01:51,820
So it says, do you want to continue?

37
00:01:51,820 --> 00:01:53,120
Yes, I do want to continue.

38
00:01:54,020 --> 00:01:56,270
And there it goes, It's going to do its thing

39
00:01:56,270 --> 00:01:57,770
when it's finished and again,

40
00:01:57,770 --> 00:02:01,370
how long it takes really depends on what's already on your system.

41
00:02:01,370 --> 00:02:03,170
So it may take a little bit longer,

42
00:02:03,170 --> 00:02:07,730
I've already got most of the stuff on my system, so we're good, let me clear the screen.

43
00:02:09,030 --> 00:02:12,530
So if you type g++ -- version, you should get some information

44
00:02:12,530 --> 00:02:13,780
about your compiler.

45
00:02:13,780 --> 00:02:17,580
This is g++, which is the GNU C++ compiler.

46
00:02:17,580 --> 00:02:20,480
And the installed version is 11.3.

47
00:02:20,480 --> 00:02:23,980
The version you have installed might be different, might be 11.4,

48
00:02:23,980 --> 00:02:27,580
12.0, 10. whatever it is, that's fine.

49
00:02:27,580 --> 00:02:31,180
They're all going to support C++ 17, unless you've got a really

50
00:02:31,180 --> 00:02:33,780
old distribution, which is very unlikely.

51
00:02:35,140 --> 00:02:38,340
All right, so the next step is to install CodeLite.

52
00:02:38,340 --> 00:02:41,600
And then once we install CodeLite, we can configure CodeLite to work

53
00:02:41,600 --> 00:02:42,200
with the compiler,

54
00:02:42,200 --> 00:02:45,000
we just installed and we should be good to go.

55
00:02:45,000 --> 00:02:48,200
So head over to CodeLite.org again

56
00:02:48,200 --> 00:02:50,200
and in the Doc section,

57
00:02:50,200 --> 00:02:52,500
you'll see this downloads link right here.

58
00:02:52,500 --> 00:02:56,000
So I'm going to select that and I'm going to click latest.

59
00:02:56,600 --> 00:03:00,600
I've got the information here, how to install for Mac, Windows, Linux.

60
00:03:00,600 --> 00:03:04,960
And this is the one we're interested in right here, the Ubuntu area.

61
00:03:04,960 --> 00:03:08,760
Now, it's all going to be terminal driven, so

62
00:03:08,760 --> 00:03:10,960
 I'm going to make some room here for my terminal.

63
00:03:11,760 --> 00:03:16,260
And really what I want to have access to these collect and copy and paste them, okay?

64
00:03:16,260 --> 00:03:18,760
So, let me open the terminal again.

65
00:03:22,860 --> 00:03:25,060
And I'm going to move the terminal just over here

66
00:03:25,060 --> 00:03:27,860
 just, so we can get it just slightly out of the way.

67
00:03:28,660 --> 00:03:30,140
Perfect, all right?

68
00:03:30,140 --> 00:03:30,940
So what we're going to do is?

69
00:03:30,940 --> 00:03:32,540
We're just going to go through this

70
00:03:32,540 --> 00:03:35,940
and basically copy these commands into the terminal and execute them.

71
00:03:35,940 --> 00:03:37,940
So the first thing we need to do is?

72
00:03:37,940 --> 00:03:39,440
We need to set the public key,

73
00:03:39,440 --> 00:03:41,640
so again I'm going to click on this little

74
00:03:41,640 --> 00:03:45,140
icon right here, then come over to my terminal.Paste,

75
00:03:46,130 --> 00:03:49,630
press the right arrow just to make sure that that's un-highlighted

76
00:03:49,630 --> 00:03:50,930
 and press enter.

77
00:03:50,930 --> 00:03:53,130
It's going to ask you for your password again.

78
00:03:55,120 --> 00:03:58,620
Notice the warning that it's deprecated, don't worry about it,

79
00:03:59,420 --> 00:04:00,920
that's a normal warning.

80
00:04:06,520 --> 00:04:09,520
All right, we're done with that, then I'm going to come down here.

81
00:04:11,720 --> 00:04:14,920
And depending on which distribution you have and again,

82
00:04:14,920 --> 00:04:17,920
there's a lot of Linux distributions out there.

83
00:04:17,920 --> 00:04:19,519
I'm using Jammy,

84
00:04:19,519 --> 00:04:22,820
which is 22.04, If you're using these other releases,

85
00:04:22,820 --> 00:04:25,020
you can use these lines here.

86
00:04:25,020 --> 00:04:26,710
So basically what I'm doing is?

87
00:04:26,710 --> 00:04:30,700
I'm going to execute this command because it's already my jammy command right here.

88
00:04:30,700 --> 00:04:32,390
But if you've got one of these,

89
00:04:32,390 --> 00:04:34,490
 you can just replace this part

90
00:04:34,490 --> 00:04:36,390
with whatever distribution you have,

91
00:04:36,390 --> 00:04:39,690
whether it's bulls eye or kinetic or whatever else you have.

92
00:04:39,690 --> 00:04:41,690
So, I'm just going to copy this.

93
00:04:42,590 --> 00:04:44,090
If you're a Linux user,

94
00:04:44,090 --> 00:04:46,390
you probably know exactly what you're doing.

95
00:04:46,390 --> 00:04:48,890
So, let me right click on here and paste it.

96
00:04:49,490 --> 00:04:52,490
Press the right arrow again and press enter.

97
00:04:57,690 --> 00:04:59,290
And it'll just be a second.

98
00:05:03,690 --> 00:05:07,290
Okay, I'm done, I'm going to clear this terminal just to make a little room here.

99
00:05:09,090 --> 00:05:12,490
All right, so I'm going to scroll up here and just a couple of more commands to run.

100
00:05:12,490 --> 00:05:15,790
I'm just going to type these in, the first one is sudo apt update.

101
00:05:16,780 --> 00:05:20,180
sudo apt update.

102
00:05:20,180 --> 00:05:21,180
Press enter.

103
00:05:25,870 --> 00:05:28,470
Okay, that's done, I'll clear it once more.

104
00:05:29,070 --> 00:05:30,670
Okay, so now what we want to do is

105
00:05:30,670 --> 00:05:33,670
We want to install the latest version, which we know is 17.

106
00:05:33,670 --> 00:05:37,030
Don't do this right here for now, just come right down here and type

107
00:05:37,030 --> 00:05:38,330
this one right here.

108
00:05:39,690 --> 00:05:42,690
Just click the icon and paste it just to make it easier.

109
00:05:46,990 --> 00:05:48,890
Okay, clear it once more.

110
00:05:50,390 --> 00:05:52,690
And now here we're going to execute this command,

111
00:05:52,690 --> 00:05:55,940
except we're going to use the 17, instead of the 14.

112
00:05:55,940 --> 00:05:57,740
Because we know that that's the latest.

113
00:05:58,240 --> 00:06:01,240
So, let me paste that.

114
00:06:02,840 --> 00:06:08,530
And I'm going to change that 4 to at 7, just like that 17.0 star.

115
00:06:08,530 --> 00:06:12,030
And that will install CodeLite and all the other dependencies that it might have.

116
00:06:12,030 --> 00:06:14,830
So this one might take a little while, but once we're done,

117
00:06:14,830 --> 00:06:17,030
we've got CodeLite installed

118
00:06:17,430 --> 00:06:21,630
and the next step is to actually run CodeLite and configure it to work with the compiler.

119
00:06:21,630 --> 00:06:24,230
Okay, so we're done with that, so let's now

120
00:06:24,230 --> 00:06:27,230
open up CodeLite and configure it to work with the compiler.
