ok, I figured out how to get it to work. It's not broken (this time!) The port cross gcc compiler(s) in freebsd are compiled with --without-includes, which removes /usr/include from the search path. So unless we specify it, it can't find anything in include paths. However, if you do -I/usr/include, it is an absolute path. The sysroot isn't applied to it. One must use -I=/usr/include - then the sysroot stuff gets appended correctly. So now I have dnsmasq and dropbear cross compiling successfully against a freebsd-head mips sysroot. Next up, lua and some tiny http server.. (And yes, we should also fix those linker scripts. :-) -adrian _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
