[U-Boot-Users] New user question(s)
Hello,
I'm attempting to build u-boot for the evb64260 brd. I'm doing so on a WinNT4 host with a Cygwin environment and a powerpc-elf cross compiler ( a Linux env is not an option ). This is fun but it's become apparent that I don't know what the heck I'm doing :^). Most of my problems seem to occur as a result of include files missing, in the wrong place, or incorrect. Here's an example of warnings/errors;

So I'm thinking my Cygwin environment is not set up correctly, or I've missed something else. In any case, has anyone built u-boot in a Win/Cygwin environment, and if so, would you have any suggestions? Any general ideas or suggestions would be appreciated as well.
Thanx,
Anders

Sincere condolences.

Please reconsider. The effort you will have to spend to get this working under Windoze is probably more expensive then investing in a standard PC running Linux.
Especially when you consider using Linux one day you will _have_ to go that route.

I think you know perfectly what you're doing: not using the right OS.
Best regards,

Please note that u-boot contains code that is supposed to run on the build host (rather than on the target), so you also need a native cygwin compiler which creates code for your x86-WinNT box. The "tools" directory above is such a directory containg tools for the host.
On a regular Linux system, you usually call the make like this:
make CROSS_COMPILE=powerpc-linux- all
The Makefiles then know where to use the "$(CROSS_COMPILE)gcc" and where to use the regular host "gcc". Be sure not to mix that up.
In general, I see no reason why u-boot should not be compilable under Cygwin. Getting there can well be a bit bumpy, though :-)
