But Windows isn't really the HOSTCC, its a cross-compile target. Setting my HOSTCC to a cross compiler seems just as confusing as setting up 2 cross-compile targets to me. The process of building would also still be slightly more complex to me: export CROSS_COMPILE=powerpc-linux- export MINGW_COMPILE=i586-mingw32msvc- make vs export HOSTCC=i586-mingw32msvc- make mkimage_win32 export HOSTCC=gcc make Best, Peter _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
