> Isn't the only difference the fact that the document conditionally > sets the --host flag No, it can cause problems because the "native" build tries to use a cross-compiler. Instead of running gcc, the build runs i486-linux-gnu-gcc or powerpc-linux-gnu-gcc. Equally, omitting --build entirely is also incorrect to ensure the correct build is specified. > I'm not sure if that makes a big difference, though I could easily be > wrong. IMHO, yes this is wrong and in line with the other cross-building support bugs, (http://lists.debian.org/debian-devel/2007/11/msg00116.html) I have created a patch that correctly handles the --build and --host statements within dh_make. Therefore, as discussed on debian-devel, please fix dh-make to implement the correct cross building support in new packages. -- Neil Williams ============= http://www.data-freedom.org/ http://www.nosoftwarepatents.com/ http://www.linux.codehelp.co.uk/
