I did a update of my macports environment and got automake 1.14 installed. The Changelog contains this:
Unsupported and changed behaviour in automake starting from version 1.14 • The AM_PROG_CC_C_O macro has been deprecated, and its use now is a no-op. Instead, the compile script is now required for all builds, and the tests executed by this macro have been bolted on the AC_PROG_CC basic macro instead. Removal of this macro is scheduled for version 2.0. • The dist-shar and dist-tarZ options have been deprecated and are scheduled to be removed for version 2.0. When enabling 1.14 in autogen.sh I get this: boost/Makefile.am:19: warning: source file 'libs/regex/src/c_regex_traits.cpp' is in a subdirectory, boost/Makefile.am:19: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. What is the correct move? I've added the subdir-objects option and this works. Stephan
