Hi Wookey,

Thanks for your response. Here is the error I get when I do the "make check" step on the foundation model after having done the "configure" and "make" steps on the x86_64 linux build machine. I used the configure options you provided.

1. On x86_64 linux build machine:
---------------------------------------------------
$./configure --prefix=/usr --enable-cxx --enable-fat --build x86_64-linux-gnu --host aarch64-linux-gnu --.target aarch64-linux-gnu --libdir=/usr/lib/aarch64-linux-gnu \
        AR=aarch64-linux-gnu-ar CC="aarch64-linux-gnu-gcc" CFLAGS="-Wall -g  -O3 -Wa,--defsym,USES_THUMB=1" \
        CXX="aarch64-linux-gnu-g++" CXXFLAGS=""
$make
. . .
build goes fine with the following final lines in the output:
. . .

You have to say _how_ it fails for anyone to have any chance of helping.

Maybe. Not sure what a coreisbr-unknown-linux-gnu is.

Here is a build log from an (ubuntu) gmp cross-build which might give some clues:
http://people.linaro.org/~wookey/buildd/quantal-arm64/sbuild-ma/gmp_2:5.0.2+dfsg-2ubuntu2arm64-quantal-bootstrap-arm64-20121117-234708.6930.log
where the configure line was:
 ../configure --prefix=/usr --enable-cxx --enable-fat --build x86_64-linux-gnu --host aarch64-linux-gnu --target aarch64-linux-gnu --libdir=/usr/lib/aarch64-linux-gnu \
        AR=aarch64-linux-gnu-ar CC="aarch64-linux-gnu-gcc" CFLAGS="-Wall -g  -O3 -Wa,--defsym,USES_THUMB=1" \
        CXX="aarch64-linux-gnu-g++" CXXFLAGS=""

There are probably some OE crossbuild logs online somewhere you could compare with too, which would be more directly relevant.
