993e51bc22introduced a <pkg>_DL_VERSION in addition to <pkg>_VERSION. This variable, purely internal to the package infrastructure, allows to store the *raw* version name, as defined in the package .mk file. However, as this version string can contain slashes, it is not appropriate to be part of the build directory name of the package. This is why <pkg>_VERSION is defined to be the same thing as <pkg>_DL_VERSION, except that slashes are replaced by underscores. However, the initial implementation didn't take into account the case of host packages. So763822e874was committed to fix this. But unfortunately, this commit got it wrong again: it forgot the case where <pkg>_VERSION is set, but not HOST_<pkg>_VERSION. In this case, HOST_<pkg>_DL_VERSION remained empty. This can be seen for example by building host-sstrip. This problem has been noticed by Julien Boibessot <julien.boibessot@free.fr>, who also helped in fixing the issue. Thanks! The fix is simply to ensure that <pkg>_DL_VERSION is properly set in all cases: when HOST_<pkg>_VERSION is defined, when only <pkg>_VERSION is defined, and when no version is defined.

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 sort of
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 (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
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 linux-menuconfig
$ make HOSTCC=gcc-4.3 uclibc-menuconfig
$ make HOSTCC=gcc-4.3 busybox-menuconfig
