This does not buld because its "configure" requires that -llzo contains "lzolx_decompress". "vtun" does not build, evenm if liblzo is available. The LZO package currently used by buildroot does not contain ANY reference to "lzolx_decompress" "vtun" has been upgraded to 3.0.2 and now builds OK, but is yet to be tested on a target. The previous patch containing three diffs, has been broken up into three files. The second patch fails. This patch tries to replace a perl script ($(VTUN_DIR)/scripts/vtund.rc.debian) with a shell script with the same name. In vtun-3.0.2, vtund.rc.debian is a shell script which is fairly similar to the shell script provided by the patch. For now, it has been decided not to replace this shell script with the script generated by the patch for 2.6 vtun will thus be built with the 3.0.2 vtund.rc.debian. The start-stop-daemon parameters and other things in this script may be inappropriate for something based on busybox. I will leave the decision which script to use, the 2-6 script or the 3.0.2 script to someone else. Both files are kept in the directory, but should be removed once it has been decided what to do about this script. Signed-Off by: Ulf Samuelsson <ulf.samuelsson@atmel.com>
To build and use the buildroot stuff, do the following:
1) run 'make menuconfig'
2) select the packages you wish to compile
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
And all the output files will be located under /tmp/build.
More finegrained configuration:
===============================
You can specify a config-file for uClibc:
$ make UCLIBC_CONFIG_FILE=/my/uClibc.config
And you can specify a config-file for busybox:
$ make BUSYBOX_CONFIG_FILE=/my/busybox.config
To use a non-standard host-compiler (if you do not have 'gcc'),
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
