'Installing' eCos sources is simply unzipping a snapshot or getting it from
CVS. The 'packages' subdirectory then becomes your 'repository'. The command
line configuration tool builds a set of Makefiles for your target. Then you
simply run 'make' to build the target library, which you then link with your
application - the Makefiles will pick the appropriate sources from the
repository.

You can either build the configuration tool yourself using native gcc or
download a pre-built binary - I have always used a pre-built binary on
Linux. Alternatively you can use the GUI based configuration tool. See the
website for more details.

That's where you're going wrong. Reading 'configure.in' and 'README.host'
may help you understand more.

You only need the native compiler to build the configuration tools (as
mentioned, you can alsoget these prebuilt from the eCos website). You need
the cross-compiler when you run 'make' as I have described.

Hope this helps
