pie/pie-a64-decoder.h: No such file or directory

I followed the instruction trying to compile the code, got following error:

MAMBO: detected architecture "aarch64"
PIE: detected architecture "aarch64"
make --no-print-directory ARCH=a64 pie

signals.c:39:10: fatal error: pie/pie-a64-decoder.h: No such file or directory
#include "pie/pie-a64-decoder.h"

compilation terminated.

and there is no pie-a64-decoder.h under subdirectory pie.

what I am missing?

thanks

Start with the failing include in signals.c and inspect the pie build target that produces pie/pie-a64-decoder.o. Check how the AArch64 decoder header is generated or referenced, then reproduce the reported make ARCH=a64 pie build. Done means the missing header is available at the expected path and the build completes.
