It can be done, but you will need the latest Cygwin > package, DLLS and a lot of patience. Ditto. Cygwin is itself pretty solid, but building cross-compilers seems to push it beyond its limits. And when it runs, it's slooooooow. Of course, if you're used to Microsoft hosts, then you've learned to expect an occasional GPF, right? :^) > If you are targeting eCos then you must use the GCC source code from the the > eCos web page.

Do the "enhancements" in the eCos-specific gcc show up in the gcc archives anywhere, or are they only being distributed via the eCos web page?

On the page: http://sourceware.cygnus.com/ecos/install-linux.html it says that you can build the Linux synthetic target with anything later than egcs-1.1.1. To the contrary, I haven't been able to do this-- only the gcc sources listed on the web page recognize the -fvtable-gc and -fdata-sections options (and other new ones). > I don't have the info with me at the moment to give you all the commands you > need to run.

I'm going through the installation instructions line-by-line, and so far everything is working for me. This is my first full day with eCos, though-- I'm not exactly an eCos power-user, yet...
