I am trying to compile/build L4Linux for an ARM-based platform.
When I execute make then I get an error saying Makeconf.l4conf cannot be found.
These are the steps I have followed to build L4Linux.

I figured that this was because I did not point to the L4Re build directory. Now I have changed that appropriately, and the build runs a bit further. Now I am getting the following error:
# make O=build/ Package libio-io was not found in the pkg-config search path. Perhaps you should add the directory containing `libio-io.pc' to the PKG_CONFIG_PATH environment variable Package 'libio-io', required by 'libio', not found Getting required compilation flags failed. L4OBJ: /root/l4re-core-2011042112/src/l4/testbuild L4_REQUIRED_MODS: stdlibs log l4re_c-util libio shmc /root/l4linux/l4linux/arch/l4/Makefile:306: *** Aborting.. Stop. make: *** [sub-make] Error 2
To build L4Linux, you need the packages that are summarized with the 'l4linux_requiremnts' keyword at the repomgr.
To build a Linux for ARM, the build command looks as follows:
$ make O=... L4ARCH=arm CROSS_COMPILER=arm-linux- arm_defconfig
Change path to corresponding l4re-objdir: $ make O=... L4ARCH=arm CROSS_COMPILER=arm-linux- menuconfig
Build: $ make O=... L4ARCH=arm CROSS_COMPILER=arm-linux- -j2
Which should result in a vmlinuz file in the Linux build root directory.
I've updated http://wiki.tudos.org/Quickstart to include a section on building L4Linux on ARM.
