You want to use the second argument of AC_OUTPUT_COMMANDS to transmit that value: AC_CHECK_HEADERS([signal.h]) AC_OUTPUT_COMMANDS([ if test x$ac_cv_header_signal_h = xyes; then echo '#include <signal.h>' >> libdir/comon.h fi ],[ ac_cv_header_signal_h=$ac_cv_header_signal_h ]) See http://sources.redhat.com/autobook/autobook/autobook_97.html for details.
