Failed to build arm64 goldfish kernel on Mac OS X - Android Q&A, Help & Troubleshooting

I have add the elf.h. Build failed to build the vdso.

I have solved the problem.
The vdso_offset_sigtramp is defined in include/generated/vdso-offsets.h
#define vdso_offset_sigtramp 0x04e0
But in my code this line is "#define vdso_offset_sigtrampt0x04e0". What the ****! I don't modify any things. Why this file changed?

Have the same problem and solved
I've got the same error message but the cause is somewhat different. My include/generated/vdso-offsets.h is empty. The reason is that arch/arm64/kernel/vdso/gen_vdso_offsets.h does not have the eXecute permission. This script is very simple, so I guess you were hit by a Mac sh or make bug.
I'm building Z00E (ASUS Zenfone 2 ZE500KL) kernel on Arch Linux x86_64.

Hey i know it's too late but i found out solution we have to change last line of this file : arch/arm64/kernel/vdso/gen_vdso_offsets.sh
to :
<code>
's/^\([0-9a-fA-F]*\) . VDSO_\([a-zA-Z0-9_]*\)$/\#define vdso_offset_\2 0x\1/p'
</code>
actually i replaced "\t" to " "(black space)
tested on sierra :fingers-crossed:
