I'm trying to build a customized u-boot (so that I can add the bootelf command, which is needed to chain Rafał's ubldr version of loader(8)). Of course, I'm trying to build this from TI's sources customized for this board, which means I'm not using the FreeBSD-customized sources from denx.de. Since ubldr is built with the native cross-tools, I've been trying to build u-boot the same way, but I've run into a few problems that make me wonder if it would make more sense to build u-boot with the cross-* ports instead, hence my question. (If I understand correctly, ubldr calls into u-boot, so the two need to be built compatibly, hence the question.) Sounds like I should keep poking at u-boot with the native cross tools…. Unfortunately, the native cross-version of ld is crashing, and I have not yet been able to successfully build a debug version of the native cross tools so I can figure out why. I'll no doubt have more questions very soon. ;-) Tim On Jan 18, 2012, at 12:37 PM, Warner Losh wrote: > The cross-* ports are more for rtems, and not for FreeBSD also... > > See 'make xdev' if you want to build native compilers in a cross-building environment. > > Warner > > On Jan 18, 2012, at 1:23 PM, Alex T. wrote: > >> If I'm not mistaken, this port is not supposed to be built directly.
