I will try to add a little clarity to the problems that some people have
encountered with brickOS under cygwin.
If you get make strip errors it is almost certainly because your utilities
were built without .exe extensions. This will happen if your makefiles do
not know that you are building on a cygwin plaform (i.e., a windows
machine). Running the configure script should correctly set EXT=.exe in
Makefile.common which will cause your utilities to be built with a .exe
extension. The configure script figures the extension out based on whether
your cross compiler has an extension. If configure did not correctly set
EXT=.exe then there is something not quite right with your cross compiler setup.
To use the pre-built hitachi cross compiler tools all you have to do is
extract the ZIP to your cygwin directory (usually c:\cygwin) using something
like WinZip. Once you've done that, running configure with brickOS newConf2
will properly find your cross compiler and will setup the Makefiles
appropriately.
If you get errors when you run firmdl or dll about not being able to open a
file then your utilities were built without -D_WIN32 which means that that
the compiler thought you were building on a Unix box of some sort. The
utilities won't work on a windows machine if they were not built with _WIN32
defined. The newConf2 release of brickOS incorrectly overwrites the value
of CFLAGS so that the utilities are not correctly built unless you edit
Makefile.common after running configure and correct the CFLAGS line in the
BUILDING_HOST_UTILS section.
Hope this helps,
