Section 27.8 of the manual, "Per-Object Flags Emulation", describes a way to accomplish this using libraries, but is that really the ideal solution? =A0It seems like a very hacky solution compared to supporting some syntax for, say, x_c_CFLAGS variables (or something that works with sources used multiple times.. perhaps a_x_c_CFLAGS), as in my example above. =A0That would be much cleaner, I would think, compared to requiring the user to create and link against useless intermediate libraries. Can this be considered for automake 1.12? Also, has anyone verified that there really is no difference between adding additional .o's to the link and .a's containing those .o's? For instance, how does this interact with LTO (link time optimization)?
