Errors compiling Liquid Z530 kernel

Nonta72

I downloaded Acer Liquid Z530 kernel source code from the support section.

I followed the steps in the README file and have compiled a kernel with DT2W drivers (DoubleTap2Wake) so that I can just double tap screen to unlock it instead of drawing "I".

The problem is that it failed to boot, bootloop...I flash my stock backup with SPFT to unbrick it.

I then started from scratch and have compiled the kernel without the DT2W drivers. Weirdly device failed to boot again.

I flashed back to stock and used a different toolchain this time: I used UBERTC toolchain (tried both ARCH=arm and ARCH=arm64). This time compiling failed even if I followed steps in the README file.

Here's the most recent attempt compiling log:

Note that the above error occurs with Google's arm ant arm64 (GCC 4.8) toolchain too! as well as NDK toolchains.

Thank you in advance for any help
