Well, now that you have a complete working toolchain, you can start building
all the components for your disk image for your pocket Linux system. A good
place to start would be to get ARM packages from the Debian site. If you want
to build 'glibc' from scratch to put on your own disk image, here is one way
of doing it.
1) Create a ramdisk using '/dev/ramX' or use the loopback device and format
an 'ext2' filesystem on it.
2) Un-pack your 'glibc' sources again.
3) Put your cross-compilation environment in your path and run the configure
script for 'glibc' only this time using '--prefix=/usr'. This will
configure 'glibc' in a special way that will install the libraries in
'/lib' like it is on a "normal" Linux system. (By telling it the prefix
is /usr AND that the target is a Linux variant, glibc figures out that
you are creating it to be the main C run time library on the system)
4) Go ahead and do a 'make' and let it finish. STOP THERE!
5) WARNING!!! Now that 'glibc' has been built you are now ready to install
it. If you were to do a 'make install' it would overwrite your host PC
libraries and you would be screwed. Instead you want to do the install
using 'make install_root=[path-to-mounted-disk-image] install'. This
will then install 'glibc' to your disk image.
6) Continue putting whatever else you want on your image.
7) Unmount disk image. Hurray, you are done.
Hope this helps.
