9	9		### Why install from .debs?
10	10
11	11		The easiest way to install Lazarus on Ubuntu is via the software Centre or Synaptic. However if that is unsuccessful or the version of Lazarus in the repository is too old and you want a newer version then you can 'install from debs'.
12	12
13	13		### .deb files
14	14
15	15		.deb files are the ideal files for installing on Ubuntu. You need to download the Lazarus .deb files you want. They will usually be on SourceForge. There will be a Lazarus .deb and a Free Pascal .deb. They will match each other.
16	16
17	17		## In Particular: Lazarus 0.9.30 on Ubuntu 10.04
18	18
19	19		### Get The files
20	20
21	21		<https://sourceforge.net/projects/lazarus/files/>
22	22
23	23		#### Repository
24	24
25	25		The versions in the Ubuntu repository are
26	26
27	27		- Lazarus 0.9.28
28	28		- Free Pascal 2.4.0
29	29
30	30		These are too old.
31	31
32	32		#### SourceForge
33	33
34	34		The versions on SourceForge are
35	35
36	36		- Lazarus 0.9.30
37	37		- Free Pascal 2.4.2
38	38
39	39		These are what I want.
40	40
41	41		#### Find SourceForge .deb files
42	42
43	43		The names of the .deb files I need to download are
44	44
45	45		- lazarus-0.9.30-i386.deb.tar (71.1MB)
46	46		- fpc-2.4.2-0.i386.deb.tar (38.5 MB)
47	47
48	48		You can search for these directly in a Search engine with something like
49	49
50		-	~~`Lazarus 0.9.30 .deb SourceForge`~~
	50	+	```text
	51	+	Lazarus 0.9.30 .deb SourceForge
	52	+	```
51	53
52	54		#### Download and Extract
53	55
54	56		Download these two files. Double click on them and accept the offer to extract.
55	57
56	58		- Extract Free Pascal into folder 'a'
57	59		- Extract Lazarus in folder 'b'.
58	60		- Move the folders onto the Desktop
59	61
60	62		#### Inside the folders
61	63
62	64		Once done, there are 21 .deb files in folder a and 12 .deb files in folder b. Two common mistakes when installing Lazarus are
63	65
64	66		- not installing Free Pascal first
65	67		- not installing Free Pascal source code.
66	68
67	69		However, notice that Free Pascal source code is one of the files in folder a. Therefore, this will NOT need to be downloaded and installed separately.
68	70
69	71		### Install Free Pascal
70	72
71	73		This should be done first.
72	74
73	75		Open a terminal.
74	76
75	77		``` bash
76	78		cd Desktop
77	79		cd a
78	80		dpkg -i *.deb
79	81		```
80	82
81	83		This last command will install Free Pascal and Free Pascal source code.
82	84
83	85		#### Errors
84	86
85	87		Ideally, everything would run smoothly and the installation would complete without error. However when I did it, there were a number of errors. These errors are sometimes 'show-stoppers' so they should be sorted out if possible. The most common error is a missing dependency, as happened to me.
86	88
87	89		#### Missing Dependencies
88	90
89	91		This means that a package that Lazarus expects to be installed on your system already is not there. The missing packages were:
90	92
91	93		- libgtk2-dev
92	94		- libogg-dev
93	95		- libvorbis-dev
94	96		- libmodplug-dev
95	97		- a52cat
96	98		- \+ a few others. If you look through the output in the terminal you will see which packages failed to install and why it was.
97	99
98	100		#### Install missing dependencies
99	101
100	102		Open Synaptic. Search for each of the missing packages and install them.
101	103
102	104		##### a52cat
103	105
104	106		This package is not in the Ubuntu 10.04 repository. We have to leave it and hope for the best.
105	107
106	108		#### Reinstall Free Pascal
107	109
108	110		Repeat the previous installation procedure with: Open a terminal.
109	111
110	112		``` bash
111	113		cd Desktop
112	114		cd a
113	115		dpkg -i *.deb
114	116		```
115	117
116	118		Free Pascal will now install fairly smoothly.
117	119
118	120		##### fp-units-multimedia
119	121
120	122		Only the multimedia unit will not install. This is due to the missing a52cat package. However it may not be critical.
121	123
122	124		#### Check the installation
123	125
124	126		You can check the Free Pascal installation in three ways:
125	127
126	128		- Run it
127	129
128	130		Open a terminal
129	131
130		-	~~`fpc`~~
	132	+	```text
	133	+	fpc
	134	+	```
131	135
132	136		it should open in the terminal.
133	137
134	138		- Look in Synaptic and check that fpc and fpc-src have been installed.
135	139		- Find the files
136	140
137	141		You can see where the files are stored with
138	142
139	143		``` bash
140	144		sudo dpkg -L fpc
141	145		```
142	146
143	147		### Install Lazarus
144	148
145	149		This is similar to Free Pascal
146	150
147	151		Open a terminal.
148	152
149	153		``` bash
150	154		cd Desktop
151	155		cd b
152	156		dpkg -i *.deb
153	157		```
154	158
155	159		and the installation will proceed.
156	160
157	161		#### Errors
158	162
159	163		An error occurs installing package lcl-qt4-0.9.30.
160	164
161	165		##### lcl-qt4-0.9.30
162	166
163	167		From the terminal output you can see that the unit can not be installed due to a dependency on ... However, if you read the information that appears in Synaptic for this package then it says
164	168
165	169		"Actually this is an empty package but ..."
166	170
167	171		I think we can safely ignore it.
168	172
169	173		#### Test
170	174
171	175		Open Lazarus and try to create a simple 'Hello World' application with a button click. It worked with mine and the installation is complete.
172	176
173	177		##### Check with Synaptic
174	178
175	179		You can check that Lazarus has been installed with Synaptic
176	180
177	181		##### Fix Broken packages
178	182
179	183		Unfortunately, I now have 2 broken packages on my Ubuntu system, fp-multimedia and lcl-qt4. I choose 'Edit/Fix broken Packages and the fp-multimedia unit goes green but the lcl-qt4 package goes bright red - not normally a good sign. However if you select
180	184
181		-	~~`Apply`~~
	185	+	```text
	186	+	Apply
	187	+	```
182	188
183	189		then Ubuntu will fix the multimedia package and remove the qt4 package. Everything is then in order.
184	190
185	191		### Final test
186	192
187	193		Create a Hello World application with a button and a label. If this works then things are looking good. Lazarus is installed.
