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.
