Hello! I'm trying to get a native Ada compiler working on ARM, but have ran into a few (primarily Makefile) problems.
Before the problem, a little background: I successfully built a cross compiler to build Ada programs from my laptop (x86_64) to the target system (Debian ARMEL). My process was pretty hackish involving a minimal install of Debian to a SD card that my embedded system (BeagleBoard) can boot from. I then copied the entire filesystem to a local directory on my laptop. Building the cross compiler became trivial when using --with-sysroot and --with-build-sysroot pointing to the copied filesystem. Now the problem: When attempting to build the native toolchain the Makefiles continually refer to my local toolchain instead of the cross compiler. Clearly, this fails to build the system and frequently it errors out with problems such as alignment warnings and invalid object format. To resolve some of the issue I modified "gcc/ada/Make-lang.in" by changing all instances of "$(GNATMAKE) -q x*" to "gnatmake -q x*" to properly build the bootstrapping toolchain. It seems that at this time in the Makefile GNATMAKE and the rest of the chain are the cross compiler, when they need to be the local toolchain. Later, and yet unresolved, the native ARM toolchain built with the Makefile under "gnattools/" attempts to use my local toolchain's include and libraries to construct it. This seems to be a problem that should be resolvable by getting the variables straightened out. Unfortunately, I don't know which variables are wrong and what they are set to. Grep isn't really helping me either. -Jake An example of the problem. Shortly thereafter it fails with one of the alignment warnings.
