For specific variables, like CFLAGS, CPPFLAGS, you may do this by using target_CFLAGS = ... > My Makefile.am says something like > > lib_LIBRARIES = libmylib.a libmylib_gcc3.a > > libmylib_a_SOURCES = foo.c bar.c > libmylib_gcc3_a_SOURCES = $(libmylib_a_SOURCES) so in this case that would be libmylib_a_CFLAGS but for the compiler (CC, CXX, ..) this is not implemented. Rationale: if you change the compiler, you most likely need to have a separate configuration (configure, configure.ac) for it. That may be achieved by using a subpackage (see Automake docs on this subject). There is a workaround, however: you can override the value of CC in a Makefile.am. I use this, for example, to invoke a compiler wrapper (mpicc) in one subdir, and use the compiler itself in all others. The subpackage solution is much safer, however. > libmylib_gcc3.a: CC=gcc3 This will not work. It states that libmylib_gcc3.a depends on a file called "CC=gcc3", I believe, from recalling portable `make' syntax.
