First, the build was failing with:
cd .. && /bin/sh /home/test/brbuild/build/cgicc-3.2.7/support/missing --run autoheader
/home/test/brbuild/build/cgicc-3.2.7/support/missing: line 52: autoheader: command not found
WARNING: `autoheader' is missing on your system. You should only need it if
you modified `acconfig.h' or `configure.ac'. You might want
to install the `Autoconf' and `GNU m4' packages. Grab them
from any GNU archive site.
That was because the PATH doesn't contain $(HOST_DIR)/usr/bin. So we
pass $(TARGET_MAKE_ENV) when calling make.
Then, the build was failing because of the crappy configure.ac and
doc/Makefile.am this project has. configure.ac checks if doxygen is
available, and if it isn't, it sets DOXYGEN to /bin/echo. Then,
doc/Makefile.am does:
DATE=`date '+%-d %b %Y'` VERSION=$(VERSION) $(DOXYGEN) Doxyfile
cp $(IMAGES) cgicc-doc.css html
mv html/index.html html/index.html.bak
When DOXYGEN=/bin/echo, then the first line does not generate anything
in html/, and the third line fails.
Therefore, we add a patch that allows to pass a --disable-doc option,
which removes the check for Doxygen. If --enable-doc is passed, then
the configure script fails if Doxygen isn't found (but in the
Buildroot case, we always pass --disable-doc to avoid the doxygen
dependency).
We also take this opportunity to bump the version of libcgicc, and to
remove a patch that is no longer needed due to this version bump.

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
