There's just a few oddballs that I need to override. This is again my fault for not being more explicit and oversimplifying my goals. For most of the project, automake handles things well. I use xx_LIBRARIES, _SOURCES, etc and AR and RANLIB do what they need to do very well. For a few libraries, however, things get screwy. Here's one example of what I did to try to overcome that which I didn't understand: lib_LIBRARIES += libmoldname.a libmoldname_a_SOURCES = isascii.c iscsym.c iscsymf.c toascii.c strcasecmp.c strncasecmp.c wcscmpi.c libmoldname_a_AR = \ $(DLLTOOL) --as $(AS) -k -U --dllname msvcrt.dll --def $(top_srcdir)/moldname-msvcrt.def --output-lib $@ ; \ $(AR) $(ARFLAGS) Now, you can see that I am essentially trying to use DLLTOOL to work in a .def file before calling $(AR), and then $(RANLIB) follows naturally. This works, but there is probably a more "correct" way of doing it. Any ideas?
