This allows me to experimentally break stuff without having to check it in first. It also give me a way to build bootable images for when (not ?if?!) I mess things up properly on the RPI. It has the advantage also of being quicker than the usual release build. > > > > (The hacks, as they stand now, are attached.

If I fix that with a symlink, clang then objects to the -ffixed-r8 option. Clang has an equivalent -ffixed-r9, but the u-boot that is mandated for FreeBSD/Arm/RPI use doesn?t have the R9 fix. > > > > Questions: > > > > 1) Are you aware of any of this? > > Yes. > > > > > 2) Do you have a quick fix idea (preferably not involving GCC)? > > No. <sigh> > > Right now, the ?get it working? answer is to install GCC XDEV tools. > > Though I tried that on a clean system last weekend and it > still failed to build.
