OK, I patched autoconf, reinstalled it, then regenerated libiberty's configure, and overrode ac_cv_prog_cc_cross (both your way and via the environment when running 'make' -- belt and suspenders.) That helped! libstdc++-v3/ltconfig still misbehaves, but at least I only had to click one dialog box instead of twenty. See below for the patch. I suspect overriding cross_compiling to 'yes' in the environment when running 'make' would convince ltconfig to not misbehave. I'll try it as soon as this build finishes. (That may be a while; building gcc on an 800MHz Celeron running Win2K and Cygnus takes about five times longer than on a nice dual 1.2GHz Linux machine...) - Dan --- /usr/share/autoconf2.13/acgeneral.m4.orig Thu Aug 22 18:26:58 2002 +++ acgeneral.m4 Thu Aug 22 19:03:12 2002 @@ -1510,11 +1510,13 @@ EOF if AC_TRY_EVAL(ac_link) && test -s conftest${ac_exeext}; then [$2]=yes - # If we can't run a trivial program, we are probably using a cross compiler. - if (./conftest; exit) 2>/dev/null; then - [$3]=no - else - [$3]=yes + if test "$[$3]" != yes; then + # If we can't run a trivial program, we are probably using a cross compiler. + if (./conftest; exit) 2>/dev/null; then + [$3]=no + else + [$3]=yes + fi fi else echo "configure: failed program was:" >&AC_FD_CC ------ Want more information?
