I’ve never seen this happen in the decade or so I’ve been doing cross builds. I’ve seen gcc breakage, but always from stupid C or C++ tricks, not from how we have things setup. > The prefixing/sysroot isn’t being setup properly, which means that you have to use $PATH to tell gcc and friends which tool you want to use (which make buildworld, etc does). One way to fix this (if we used autoconf in the base system build) would be to reconfigure it with a particular sysroot: > > $ ./configure --help | grep -A 3 sysroot > --with-build-sysroot=sysroot > use sysroot as the system root during the build > --with-sysroot=DIR Search for usr/lib, usr/include, et al, within DIR. > --with-gnu-ld assume the C compiler uses GNU ld default=no > --with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib > --without-libiconv-prefix don't search for libiconv in includedir and libdir > $ svn info configure | grep ^URL: > URL: svn+ssh://ngie@svn.freebsd.org/base/head/contrib/gcc/configure The native-xtools builds should be setup to use the right binaries. I don’t think this is sean’s problem.
