--- Comment #9 from Georg-Johann Lay <gjl at gcc dot gnu.org> 2012-12-03 13:37:35 UTC --- (In reply to comment #8) > OK, but the question is why this rule is invoked during the gnattools build? > Moreover, why does s-avr-mlib need to be rebuilt at this point since it has > presumably already been built for the target libraries? I don't know anything about the gnat build system and when I build avr-gcc I configure for C/C++. What's odd is that even if GCC is only configured for C/C++, I get messages about a missing gnatls. For example, running make in the gcc subdirectory of build prints $build/gcc> make /bin/sh: gnatls: command not found The build itself works fine but that message is confusing and shows that something is wrong with the gnat build system. gnat stuff should not be needed of the compiler is not configured for ada, should it?
