dnl Like AC_TRY_EVAL but also errors out if the compiler generates dnl _any_ output. Some compilers might issue warnings which we want dnl to catch. AC_DEFUN([AC_TRY_EVAL2], [{ (eval echo configure:__oline__: \"[$]$1\") 1>&AC_FD_CC; dnl (eval [$]$1) 2>&AC_FD_CC; _out=`eval [$]$1 2>&1` && test "x$_out" = x; }]) dnl Like AC_TRY_COMPILE but calls AC_TRY_EVAL2 instead of AC_TRY_EVAL AC_DEFUN([AC_TRY_COMPILE2], [cat > conftest.$ac_ext <<EOF [#]line __oline__ "configure" #include "confdefs.h" [$1] int main(void) { [$2] ; return 0; } EOF if AC_TRY_EVAL2(ac_compile); then ifelse([$3], , :, [rm -rf conftest* $3]) else echo "configure: failed program was:" >&AC_FD_CC cat conftest.$ac_ext >&AC_FD_CC ifelse([$4], , , [ rm -rf conftest* $4 ])dnl fi rm -f conftest*])
