i've just tried to build the 2.95 and 3.2.1 toolchains for an i686-linux host
and arm-linux target.  i ran into the same problem with both builds.  as soon
as i reach the uClibc/ldso/ldso directory, the build fails on arm/resolve.S.

it looks like the native compiler is being used to assemble the target assembly
file.  build/uClibc/Rules.mak has 'CROSS=', which looks suspicious.  the perl
line in the top level Makefile is supposed to fill that in with TARGET_CROSS,
but i don;t see TARGET_CROSS anywhere in the toolchain project.



all i've done is check out the toolchain project, edited the TARGET_PATH and
ARCH in the Makefile, and typed make.  should i be specifying TARGET_CROSS
somehow when i build a cross uClibc?  do i need to have a working
cross-compiler first to build the uClibc toolchain, or should it be completely
self-boot-strapping?



thanks
