I'm still pretty confused how the automake variables work. Perhaps someone could answer my questions. 1. I get it that they are just existing per Makfile in one directory. But what is then meant when the documentation talks about global variables? Does global mean they are predefined?
2. When I actually add e.g. AC_SUBST([SOMETHING]) into a configure.in - what is the AC_SUBST doing? 3. Does the order of assigning variables make any difference? AM_CFLAGS = blub SUBDIRS = . somedir AM_CFLAGS = whatever Assuming that AM_CFLAGS is also accessible by the subdirectories, - would AM_CFLAGS have the value "blub" or "whatever"?
