A very complex example is what OpenMPI uses, a rather simple one would be this untested example: -- configure.ac snippet -- AC_ARG_ENABLE([pdp], [AS_HELP_STRING([--disable-pdp], [disable pdp library]) # foolib is needed by pdplib so AC_CHECK_LIB([foolib], [foofunc], [], [enable_pdp=no]) AM_CONDITIONAL([ENABLE_PDP], [test "$enable_pdp" != no]) -- Makefile.am snippet -- if ENABLE_PDP lib_LTLIBRARIES = libpdp.la libpdp_la_SOURCES = foo.c ... endif Hope that helps.
