With "some macro", you mean "some prepended or appended makefile.am snippet" here, right? > If, for example, there would be some > logic consisting of OUTPUT_HEADER OUTPUT_CONTENT OUTPUT_FOOTER > could someone overwrite one of them to add some lines? > I guess this probably could be more flexible (but no idea if this > makes any sense in this context). Well, my idea of the above would be that if you used AM_MAKEFILE_APPEND([bot1]) AM_MAKEFILE_APPEND([bot2]) AM_MAKEFILE_PREPEND([top2]) AM_MAKEFILE_PREPEND([top1]) then that would amount to the same as if you had added this to your Makefile.am: include $(top_srcdir)/top1 include $(top_srcdir)/top2 ... rest of Makefile.am contents ... include $(top_srcdir)/bot1 include $(top_srcdir)/bot2 In that way, adding more lines would be easy. However, overwriting lines from 'top1' after that AM_MAKEFILE_PREPEND would not be easy. In order to achieve something like that, we'd have to have a scheme to identify included snippets by number or name, and maybe priority. Do you have a good use case for this overwriting (that would justify this complication)? Thanks, Ralf
