Instead of the pattern above, what will probably work is to use the conditional to select between an installable libtool library or a libtool convenience library, so that libtool is used in both cases. For example (untested): if LIBRARY_BUILD lib_LTLIBRARIES = libprog.la else noinst_LTLIBRARIES = libprog.la bin_PROGRAMS = driver endif libprog_la_SOURCES = a.c b.c d.c driver_SOURCES = driver.c driver_LDADD = libprog.la > if LIBRARY_BUILD > a.lo: a.c b.lo > b.lo: b.c > d.lo: d.c a.lo b.lo > else !LIBRARY_BUILD > a.o: a.c b.o > b.o: b.c > d.o: d.c a.o b.o > driver.o: driver.c a.o b.o d.o > endif !LIBRARY_BUILD Then with the above change, the "else" case of this conditional is now not required. Note that regardless of what you do, these prerequisites look very odd as they say that object files depend on other object files (which would imply that b.o is somehow required to update a.o: very unusual in a C program). Moreover, Automake already provides prerequisites from object files to their C source files, so listing the .c files here is redundant.
