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.

Hello Anil,
Apparently, this package does not like to be configured and compiled on one arch and then tested on another. And frankly, this is somewhat of an exotic case, so I am not sure how representative your test results are going to be.
I think there are two ways to address this: - create symlinks with aarch64-linux-gnu- prefix linking to gcc, ld, as etc on the model as required; - do the build on the model using distcc, this way the actual compilation work will be performed on your build machine but the source and build trees would live inside the model (perhaps someone else could confirm whether distcc needs elaborate support in the project usually, but I don't think this is the case)
Regards, Ard.

Hi,
I am trying to cross compile a package wi the following steps. The build goes fine except that when I try to run the same on the foundation model it doesn't work. Here are all the steps in details:
- Installed the linaro gcc and set up the environment as follows:
export
AARCH64_TOOLCHAIN=/home/anilss/Linaro/tools/gcc-linaro-aarch64-linux-gnu-4.7-2013.04-20130415_linux/bin export PATH=$PATH:$AARCH64_TOOLCHAIN export ARCH=aarch64 export CROSS_COMPILE=aarch64-linux-gnu-
- Now on my build machine (x86_64 machine running linux), from
source root of the package (i.e. GMP) I want to cross compile:
anilss@anilss:~/Linaro/pkgs/gmp/cross_arm64/gmp-5.1.3-aarch64$./configure --build=coreisbr-unknown-linux-gnu --host=aarch64-linux-gnu --target=aarch64-linux-gnu anilss@anilss:~/Linaro/pkgs/gmp/cross_arm64/gmp-5.1.3-aarch64$make
- Then On the foundation model, where the above source tree is
mounted, I do: $ make check
However this fails.
You have to say _how_ it fails for anyone to have any chance of helping.
Any ideas on what is going wrong..? Also is the triplet correct for host and foundation model (running oe linux)?
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+... 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.
