Could you please let me know this can be cross_compiled???

srinivasan@tata-HP-Elite-7100-Microtower-PC:~/alsa-lib-1.0.26/test$ arm-linux-gnueabihf-gcc latency.c -o latency.o -lasound

/opt/ti-sdk-am335x-evm-07.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin/../lib/gcc/arm-linux-gnueabihf/4.7.3/../../../../arm-linux-gnueabihf/bin/ld: /tmp/ccPwvMUd.o: undefined reference to symbol 'sin@@GLIBC_2.4'

    Good to hear this.

    These are the steps for configuring & installing the jack in TI SDK 8 rootfs:

     git clone git://arago-project.org/git/projects/oe-layersetup.git tisdk
 cd tisdk
 ./oe-layertool-setup.sh -f configs/amsdk/amsdk-08.00.00.00-config.txt
 cd build
 echo 'EXTRA_APPLICATIONS_append = " jack"' >> conf/local.conf
 . conf/setenv
 export PATH=$HOME/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/bin:$PATH
 MACHINE=am335x-evm bitbake tisdk-rootfs-image
