I'm Trying to install TensorFlow on ARM Board (my platform is: ODROID XU4) By cross compiling using bazel and linaro compiler.
I have done this steps:
- Download Linaro 4.9.4 for armeabihf
- Adding This lines to WORKSPACE file
new_local_repository(
name = 'toolchain_target_arm_linux_gnueabihf',
path = '/home/system/Clones/CrossCompileTF/toolchain/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf',
build_file = 'arm-compiler/cross_toolchain_target_arm_linux_gnueabihf_host_x86-64.BUILD'
- And creating CROSSTOOL, BUILD and cross_toolchain_target_arm_linux_gnueabi_host_x86-64.BUILD files as you seen bottom:
