This is the command line I used to build boost using Bjam for an arm platform, not sure if that helps with what you need, but here it is anyway!!
bjam "-sGCC_ROOT_DIRECTORY=/opt/montavista/mobilinux/devkit/arm/iwmmxt_le" "-sGCC=iwmmxt_le-gcc" "-sGXX=iwmmxt_le-g++" stage
Stage is the folder in which all the libs are placed, other parameters should be self explanatory.

Thanks, I finally got this to build by inserting "GCC=$(STAGING_DIR)/arm-elf-linux" in my $(MAKE) .... all target in the boost.mk file in my Buildroot system. [Though I think I'm going to have to change the toolchain to use "arm-linux-eabi" soon] Had to explicitly state 'arm-elf-linux' so that the unprefixed tool names (e.g. gcc, ld ...) as used by boost build would work OK. Couldn't find an option to prefix 'arm-elf-linux-' to all the toolnames; the above-mentioned GCC and GXX options don't affect the rest of the tools. There ought to be a TOOL_PREFIX option ... Thanks again, Mike
