I was inspired by the clang build world topic to try a cross build world
of ARM from a i386 computer.
I use the build command:
make TARGET_ARCH=arm TARGET_CPUTYPE=xscale buildworld
(I tried an "TARGET_CPUTYPE=cortex-a8" once also, I got the same errors
below).
/etc/src.conf is taken from the FreeBSD clang web page,.
/etc/make.conf has perl version strings.
The cross tools build stage apparently makes an i386 compiler:
/usr/obj/arm.arm/usr/src/tmp/usr/bin/clang -###
FreeBSD clang version 2.8 (branches/release_28 114020) 20100917
Target: i386-undermydesk-freebsd9.0
Thread model: posix
When the library build stage begins, the assembler complains about the
unknown "--32" option from clang. I know the "--32" options is a i386
target add-on option. Removing "--32" from the command line with a
script shim, and sure enough clang is generating i386 assembly code.
I know the clang and ARM is not tested nor supported. I am just looking
for some clang cross architecture compiling wisdom.
Clang is not yet ready for use as a cross-compiler, although support for
it should be relatively easy to add. This is still being worked on
upstream. See also this thread:
