I don't any experience with cross compilation, but AIUI what you try to achieve doesn't fit in the Autotools model. What you have to do is to provide a generic build instruction: --8<---------------cut here---------------start------------->8--- bin_PROGRAMS = event event_SOURCES = event.c --8<---------------cut here---------------end--------------->8--- Then when running './configure' you have to define the "--build", "--host", and "--target" options according to the architecture you want compile [1][2]. If you want to automate this process for multiple architectures, you have to create a script running './configure ... && make' multiples times I am closing this bug. If you have questions regarding cross compilation with Automake feel free to ask them on <autom...@gnu.org>.
