How would you propose we implement this: - in a pre-configure hook (but that will catch the failure late in the build) ? - in a make ifeq-block (so we can catch it early in the build) ? The second solution is more appealing to me, but might be a bit more complex to implement. > - add (BR2_i386 && BR2_HOSTARCH='i386') to the config.in to exlude > such combination. But that would prevent the combination on systems that are setup with support for building 32-bit programs, which is a pity... Regards, Yann E.
