In that case, you must admit it is strange that gcc on FreeBSD amd64 has a-m32 support which does not work! I see two options that work equally well for me: - remove -m32 option on gcc amd64, distro will reduce - add /usr/include32 which gcc will use instead of /usr/include in case -m32 is passed (or something similar) NetBSD requires a 32bit OS version to compile and use 32bit programs. At least it is clear. Christian -----Original Message----- From: John Baldwin [mailto:jhb@freebsd.org] Sent: mercredi 25 janvier 2012 14:37 To: freebsd-amd64@freebsd.org Cc: C.

Yes, -m32 doesn't work currently as it uses the wrong set of headers (/usr/include/machine references amd64 headers, not i386 headers). -- John Baldwin
