Hi,
I also follow this intructions, but after final step:
make ARCH=arm CROSS_COMPILE=${NDK_TOOLCHAIN}
CFLAGS="--sysroot=${NDK_SYSROOT}"
I received error:
config/Makefile:159: *** No gnu/libc-version.h found, please install
glibc-dev[el]/glibc-static. Stop.
I search and know that gnu/libc-version.h appears in my aosp
r/prebuilt/linux-x86/toolchain/i686-linux-glibc2.7-4.4.3/sysroot/usr/include/gnu/libc-version.h
and /usr/include/x86_64-linux-gnu/gnu/libc-version.h
What's wrong?
