Hi, the project I am working on uses GNU autotools as build system and has the following structure:
app/ lib/ modules/ configure.ac Makefile.am We use one central Makefile.am to avoid the recursive use of make. This central Makefile.am contains all information related to app/ and lib/. However each module defines its build system information in an own Makefile.am that is located in modules/. A typical module-Makefile.am looks like this: ---------- module Makefile.am ---------- lib_LTLIBRARIES += modules/update/app/libupdate.la modules_update_app_libupdate_la_SOURCES = modules/update/app/update.c app_app_LDADD += modules/update/app/libupdate.la ---------------------------------------- By default each module Makefile.am should be included to the central Makefile.am. Furthermore it should be possible to disable modules per configure option. That is to not include the corresponding module Makefile.am. My first approach was to include an intermediate file generated by configure. This file (e.g. Makefile.modules) is always included by Makefile.am. Each configure run changes the content of Makefile.modules according to the module configuration. This solution works for in-tree builds, but there are problems with VPATH builds and the make distcheck target. Anyway I want to get rid of this intermediate file. Therfore I'm searching a way to include the module Makefile.am's to the central Makefile.am, but without knowing which or how many modules exists. Since includes with wildcards (as in GNU make), don't work in automake, I've no idea how to realize that. I use automake 1.11 and autoconf 2.13. Is there a way to realize the explained functionality? Thank you, Tim
