verison of capstone does not support MIPS instruction

[ksloven]

Hi,

I have installed T-Fuzz on Windows Subsystem for Linux (Ubuntu). and I get the following error:

WARNING | 2018-06-10 10:28:51,171 | angr.analyses.disassembly_utils | Your verison of capstone does not support MIPS instruction groups.
Traceback (most recent call last):
  File "./TFuzz", line 64, in <module>

    with open("/proc/sys/kernel/core_pattern") as f:
IOError: [Errno 2] No such file or directory: '/proc/sys/kernel/core_pattern'

Any pointers around this?

From angr discussions (https://github.com/angr/angr/issues/819):

• Not supporting MIPS instruction groups is usually not a problem if you want to analyze MIPS firmware. It is only a problem for packages relying on the Disassembly analysis, as it cannot tell whether an instruction is a call/branch or not without the instruction groups support.
• The MIPS instruction groups support only exists in capstone v4. You'll want to manually install the next branch of the capstone engine.

@ksloven thanks for the feedback.

Please run the script in scripts/kernel_config.sh

@ksloven yeah, as @chubbymaggie said, just ignore it for the moment.
