I'm trying to build a customized u-boot (so that I can add the bootelf command, which is needed to chain Rafa=C5=82'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=E2=80=A6. 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... >=20 > See 'make xdev' if you want to build native compilers in a = cross-building environment. >=20 > Warner >=20 > On Jan 18, 2012, at 1:23 PM, Alex T. wrote: >=20 >> If I'm not mistaken, this port is not supposed to be built directly. = Well, >> you may, but >> from what I see is that there one is supposed to build = devel/arm-rtems-gcc, >> which in >> its turn defines mentioned variables and builds cross-gcc port. >> And it looks like the only pair of values is supported is arm/rtems. >>=20 >> On 18 January 2012 07:30, Tim Kientzle <kientzle@freebsd.org> wrote: >>=20 >>> What TGTARCH/TGTABI settings for cross-gcc >>> and cross-binutils match the native arm.arm cross >>> toolchain? >>>=20 >>> Tim
