4 | 1 | Xavier León | |
5 | 6 | Pau Escrich | You need some packages like: gcc, make, zlib, flex, quilt, subversion and some others. Also you need to install the devel packages of each of them. But don't worry about this, during the compilation process openwrt will tell you which one is missing. |
6 | 1 | Xavier León | |
7 | 4 | Pau Escrich | First of all we are going to download the sources: |
8 | <pre> |
||
9 | svn co svn://svn.openwrt.org/openwrt/branches/backfire |
||
10 | </pre> |
||
11 | 1 | Xavier León | |
12 | 4 | Pau Escrich | A good practice is to put download directory (where all packages will be stored) outside your source directoy. By this way you can use it for more source checkouts. |
13 | 1 | Xavier León | |
14 | 4 | Pau Escrich | <pre> |
15 | cd backfire |
||
16 | mkdir ../dl |
||
17 | ln -s ../dl |
||
18 | </pre> |
||
19 | |||
20 | Let's go to install all feeds (extra packages). |
||
21 | <pre> |
||
22 | scripts/feeds update -a |
||
23 | scripts/feeds install -a |
||
24 | </pre> |
||
25 | |||
26 | And now we can start with configuration process: |
||
27 | <pre> |
||
28 | make menuconfig |
||
29 | make kernel_menuconfig |
||
30 | </pre> |
||
31 | |||
32 | menuconfig: you can select the packages you want to have inside your system installed (*) or only avaiable to install (M) |
||
33 | kernel_menuconfig: this is the standard menuconfig of the linux vanilla kernel |
||
34 | |||
35 | Then we can start compilation: |
||
36 | <pre> |
||
37 | make V=99 |
||
38 | </pre> |
||
39 | First time it can have one or more hours. |
||
40 | |||
41 | If all goes fine. You will find the images ready to install inside: bin/ARCH/openwrt-* |
||
42 | |||
43 | For instance, if you want to use squashfs image using a USB pendrive, SD or CF: |
||
44 | <pre> |
||
45 | dd if=openwrt-*-generic-combined-squashfs.img of=/dev/sdX |
||
46 | </pre> |
||
47 | |||
48 | The first time openWRT boots, you can access using telnet to change the password. |
||
49 | |||
50 | <pre> |
||
51 | 1 | Xavier León | telnet 192.168.1.1 |
52 | passwd root |
||
53 | reboot |
||
54 | 4 | Pau Escrich | </pre> |
55 | 1 | Xavier León | |
56 | 4 | Pau Escrich | After that, telnet session will disappear. Then you can use ssh to manage the device. |

62 | Requirements: |
||
63 | Need packages: |
||
64 | * /bin/bash |
||
65 | * python |
||
66 | * perl |
||
67 | * lvm2 |
||
68 | |||
69 | Filesystem: |
||
70 | * /etc/resolv.conf cannot be a symbolic link |
||
71 | * /boot should be copied from build_dir/linux*/root.grub/boot (script in /home/xleon) |
||
72 | |||
73 | once copied in myplc, remember to do a sha1sum of the bootstrapfs-openwrt.... |
