And hacking the Makefile a lot to specify command line arguments in the compiler program definition itself, so that the /usr/include/g++ files that came with the old compiler are not used for "make release" and other types of make targets where DESTDIR is fairly mandatory. See /usr/src/share/mk/bsd.prog.mk, ~line 14: .if defined(DESTDIR) && !defined(BOOTSTRAPPING) CFLAGS+= -I${DESTDIR}/usr/include CXXINCLUDES+= -I${DESTDIR}/usr/include/g++ .endif See also /usr/src/share/mk/bsd.lib.mk, ~line 40. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
