Dear list, I have a program that when cross compiled need a program that must be built on the build platform (assuming cross compiling when build != host and host == target). Like I've read on the autotool book, on the autoconf manual and on the autoconf forum I've tried to use the CC_FOR_BUILD substituition variable and the config.guess and config.sub invoking AC_CANONICAL_BUILD/AC_CANONICAL_HOST/AC_CANONICAL_TARGET. After this macros, running ./configure using --build=i686-pc-linux-gnu --host=powerpc-7450-linux-gnu, CC_FOR_BUILD is empty. But this is not my only problem because I need to use AR, RANLIB and LD from the Makefiles and I can't find AR_FOR_BUILD and co. Have you got any suggestions?
