Makefiles and config.m4

I'm buiding new extension and I got problems with config.m4. I have external object files that should be linked into PHP binary. I ran configure and after that I added those object files to main Makefile PROGRAM_LDADD = libphp4.la $(EXT_PROGRAM_LDADD) myexternal.o myexternal2.o myexternal3.o etc I have made file external.obj in directory ext/progress that contains all object files to be added so it can loopped and the $PROGRESS_DIR can be added before file names (for right path) How can make configure to do that for me? Now my config.m4 look like this: PHP_ARG_WITH(progress, for progress support, [ --with-progress Include progress support]) if test "$PHP_PROGRESS" != "no"; then if test -r $PHP_PROGRESS/; then # path given as parameter PROGRESS_DIR=$PHP_PROGRESS fi if test -z "$PROGRESS_DIR"; then AC_MSG_RESULT(Progress DLC path not given.) AC_MSG_ERROR(Please give Progress DLC path.) fi PHP_ADD_INCLUDE($PROGRESS_DIR/probuild/esqlc) LIBS="$LIBS -L$PROGRESS_DIR/probuild/4gl -lm -ldl -lavcall" PHP_EXTENSION(progress, $ext_shared) fi
