11	11		To install Lazarus you install three things:
12	12
13	13		- fpc - the Free Pascal compiler
14	14		- fpc-src - the source code for Free Pascal
15	15		- Lazarus -the IDE for Free Pascal
16	16
17	17		### Versions

19	19		You must install the correct version of Free Pascal for the version of Lazarus you choose. The versions below are correct.
20	20
21	21		## Ubuntu 11.10 (Oneiric Ocelot)
22	22
23	23		### What you want
24	24
25	25		Matching versions of Lazarus and Free Pascal are in the repository (20/02/12). They are
26	26
27	27		- Lazarus 0.9.30-2.
28	28		- Free Pascal 2.4.4
29	29
30	30		In Synaptic they are called Lazarus 0.9.30-2Build1, fpc, and fp.
31	31
32	32		### Find and install the packages
33	33
34	34		In the Software Centre search for and install:
35	35
36	36		- IDE for FreePascal - SDK metapackage - search under lazarus
37	37		- Free Pascal - SDK metapackage - search under fpc
38	38		- FreePascal - SDK source code metapackage- search under fpc
39	39
40	40		With Synaptic, install everything beginning with Laz, fpc or fp.
41	41
42	42		### Problem 1
43	43
44	44		Once you have installed Lazarus, it will not work. Even if you add no code at all and compile and run everyone's favourite 'Blank form' project (having first saved it of course) you will get this error message:
45	45
46	46		`Project project1 raised Exception class EInterface critical with message: ....`
47	47
48	48		### Solution (10 mins): Remove the Ubuntu taskbar menu and overlay scrollbars
49	49
50	50		- Remove the taskbar
51	51
52	52		Open a terminal and try
53	53
54	54		`sudo apt-get remove appmenu-gtk3 appmenu-gtk appmenu-qt`
55	55
56	56		Give your password These can be re-installed if needed with the same command but put 'install' in place of 'remove'.
57	57
58	58		- Remove the Ubuntu overlay scrollbars
59	59
60	60		Open synaptic and search for 'liboverlay-scrollbar'.
61	61
62	62		Uninstall the 2 packages highlighted. They can be re-installed if needed with Synaptic
63	63
64	64		`You now need to restart Ubuntu and hope.`
65	65
66	66		The 'blank form' project should now run with no errors.
67	67
68	68		### Problem 2
69	69
70	70		Add a button to your 'blank form' project. In the Events tab of theObject Inspector , try to open the 'Click' event handler. You will get the error message
71	71
72	72		`unit not found: Classes`
73	73
74	74		or
75	75
76	76		`unit not found: Sysutils`
77	77
78	78		### Solution (10 mins): Reconfigure Lazarus as sudo
79	79
80	80		This can be solved as follows:
81	81
82	82		- Open Lazarus as sudo
83	83
84	84		Open a terminal and start Lazarus as sudo with
85	85
86	86		`gksudo StartLazarus`
87	87
88	88		Give your sudo password
89	89
90	90		- Rescan the Pascal source directory
91	91
92	92		In Lazarus choose
93	93
94	94		`Tools -> Rescan FPC source directory`
95	95
96	96		- Rebuild Lazarus
97	97
98	98		In Lazarus choose
99	99
100	100		`Tools -> BuildLazarus with profile:Build all`
101	101
102	102		- Close Lazarus.
103	103
104	104		You should now be able to open Lazarus normally and create a project with a button that is clickable!'
105	105
106	106		'Hello World' here we come.
107	107
108	108		Oh Joy!
