To build and use the buildroot stuff, do the following:
|
|
|
|
|
2007-08-01 02:11:48 -06:00
|
|
|
1) run 'make menuconfig'
|
2005-02-07 16:01:20 -07:00
|
|
|
2) select the packages you wish to compile
|
2004-10-09 00:27:44 -06:00
|
|
|
3) run 'make'
|
|
|
|
4) wait while it compiles
|

|
|
|
5) Use your shiny new root filesystem. Depending on which sortof
|
|
|
|
root filesystem you selected, you may want to loop mount it,
|
|
|
|
chroot into it, nfs mount it on your target device, burn it
|
|
|
|
to flash, or whatever is appropriate for your target system.

|
|
|
|
You do not need to be root to build or run buildroot. Have fun!

Offline build:
|
|
|
|
==============
|
|
|
|
|
|
|
|
In order to do an offline-build (not connected to the net), fetch all
|
|
|
|
selected source by issuing a
|
|
|
|
$ make source
|
|
|
|
|
|
|
|
before you disconnect.
|
|
|
|
If your build-host is never connected, then you have to copy buildroot
|
|
|
|
and your toplevel .config to a machine that has an internet-connection
|
|
|
|
and issue "make source" there, then copy the content of your dl/ dir to
|
|
|
|
the build-host.

Building out-of-tree:
|
|
|
|
=====================
|
|
|
|
|
|
|
|
Buildroot supports building out of tree with a syntax similar
|
|
|
|
to the Linux kernel. To use it, add O=<directory> to the
|
|
|
|
make command line, E.G.:
|
|
|
|
|
|
|
|
$ make O=/tmp/build
|
|
|
|
|
2010-06-21 15:07:12 -06:00
|
|
|
And all the output files (including .config) will be located under /tmp/build.

|
|
|
More finegrained configuration:
|
|
|
|
===============================
|
|
|
|
|
|
|
|
You can specify a config-file for uClibc:
|
|
|
|
$ make UCLIBC_CONFIG_FILE=/my/uClibc.config
|
|
|
|
|
2007-09-02 11:44:09 -06:00
|
|
|
And you can specify a config-file for busybox:
|
|
|
|
$ make BUSYBOX_CONFIG_FILE=/my/busybox.config
|
|
|
|
|
2008-06-23 07:40:34 -06:00
|
|
|
To use a non-standard host-compiler (if you do not have 'gcc'),
|
2006-12-22 05:11:06 -07:00
|
|
|
make sure that the compiler is in your PATH and that the library paths are
|
|
|
|
setup properly, if your compiler is built dynamically:
|
|
|
|
$ make HOSTCC=gcc-4.3.orig HOSTCXX=gcc-4.3-mine
|
|
|
|
|
|
|
|
Depending on your configuration, there are some targets you can use to
|
|
|
|
use menuconfig of certain packages. This includes:
|
|
|
|
$ make HOSTCC=gcc-4.3 linux26-menuconfig
|
|
|
|
$ make HOSTCC=gcc-4.3 uclibc-menuconfig
|
|
|
|
$ make HOSTCC=gcc-4.3 busybox-menuconfig
|
