By default, the AC_LIB_LINKFLAGS_BODY macro will search in $prefix/include and $prefix/lib, where $prefix is given through the --prefix option. This is needed for the quite frequent use of people that build many GNU packages into the same $prefix directory. By specifying --without-libFOO-prefix you disable this search directory, so that the search will only consider /usr/include and /usr/lib (and possibly others that the compiler uses, through CPPFLAGS etc.). > Further, does this macro handle 64-bit libraries in $prefix/lib64? No. Excellent point. I need to work on that. Is there a standard convention that would tell me whether to look in lib or lib64? Seems to be OS dependent, CPU dependent (seen on x86_64 and sparc64 but not on alpha), and compiler mode dependent (whether sizeof(long) == 8 or == 4), no?
