error adding symbols: file in wrong format

Hello, compiling with your instructions (using cross compile) I face this problem. How can I solve it?

Please check whether you have used same compiler aarch64-linux-gnu-gcc to compile bolt and png. you can use readelf tool to check the library.

You need to add following variables before compiling png.

export PATH=<directory to aarch64-linux-gnu-gcc>/bin:$PATH
export CC=aarch64-linux-gnu-gcc
export CXX=aarch64-linux-gnu-g++

@yuxianzhi, thanks for your reply. Recompiled all the libs with aarch64-linux-gnu-gcc, but still getting the same error.

@yuxianzhi nevermind, now I'm getting error:
imTrans.c:56:10: fatal error: X11/Xatom.h: No such file or directory #include <X11/Xatom.h>
and similar. Do I need to link X11 from /usr/include to aarch64-linux-gnu-gcc somehow? By the way, there is no configure file in libxau, libxcb and libx11, @jianfeifeng, edit build_dependency.sh in bolt/image, please.
