Replace Rowboat default Kernel with Kernel 3.8
Note 1: SGX is not yet supported on Kernel 3.8 so there is no hardware-accelerated OpenGL on this release./pre>Note 2: Consider Rowboat for BeagleBone Black was cloned at ~/rowboat-android-bbb and Kernel 3.8 is at ~/linux-dev
mv kernel kernel.bkp
ln -s ~/linux-dev/KERNEL kernel
Let's modify some Makefiles in order to use 'arm-linux-gnueabihf-' instead of 'arm-eabi' for compiling.
chmod 644 ~/rowboat-android-bbb/Makefile
And add a # (comment) in front of
export PATH :=$(PATH):$(ANDROID_INSTALL_DIR)/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin.
Below that (new) comment add the following two lines and save
export PATH :=~/linux-dev/dl/gcc-linaro-arm-linux-gnueabihf-4.7-2013.04-20130415_linux/bin:$(PATH)
export CC_PREFIX := arm-linux-gnueabihf-
Search the Makefile for references to
arm-eabi-and replace them with
$(CC_PREFIX). Once all the changes are saved, go on building Android with SGX support.
