I confirm this behaviour. You can stick the targets wordsize into BUILD_CFLAGS=-m32 or keep it passing in via HOSTCC, of course. I did not look to see if we could tweak byteswapping (or to work for the case where the host is able to run binaries of a lower wordsize via STANDALONE support). _______________________________________________ uClibc mailing list uClibc@uclibc.org http://lists.busybox.net/mailman/listinfo/uclibc
