Hello All,
I am porting DMTCP to Android 7.0 and the OS is 64bit.
When I compile mtcp, it failed in building mtcp library (libmtcp.a).
The libmtcp.a is generated from syscall-aarch64.S and restore_libc.c which is
written with ASM code.
It failed in compiling.
Is there any Android.mk for reference?
I comment the mtcp_syscall usage in the source code to make it pass to build.
And it has segment default error like below. Please support to verify this
error.
Thanks a lost
