No global L located (tried globalL and ngx_cycle)
(gdb)
my OSX is 10.11.2 (15C50).
I installed OpenResty with those options:
./configure --with-cc-opt='-I/usr/local/Cellar/pcre/8.37/include/' --with-ld-opt='-L/usr/local/Cellar/pcre/8.37/lib' --with-openssl=/Users/zhoujing/Downloads/openssl-1.0.2e --with-debug --with-dtrace=/usr/sbin/dtrace --prefix=/usr/local/nginx_x
and make like:
make CCDEBUG=-g
make CCDEBUG=-g install
even though i renew the CCDEBUG option in luajit source code
/Users/zhoujing/Downloads/ngx_openresty-1.9.3.2/bundle/LuaJIT-2.1-20151028/src/Makefile, I still got fail.
here are many info I run in gdb. what should I do to solve this No global L located (tried globalL and ngx_cycle)mistake? Thanks every much.

unsure how to install
I'm not sure how this is supposed to be installed. Should I cd my way into the repo and then source luajit2.1.py and then run as usual? if I do this I get
(gdb) cd openresty-gdb-utils/
Working directory /home/caps/goluwa/data/bin/linux_x64/openresty-gdb-utils.
(gdb) source luajit21.py
Traceback (most recent call last):
File "luajit21.py", line 4, in <module>
import gdbutils
ImportError: No module named 'gdbutils'
(gdb)
I feel like I'm missing something obvious here as I'm not very experienced with GDB.
(initially i made this issue with nothing and a + sign by accidentally hitting enter or something)

gdb.error: No global L located (tried globalL and ngx_cycle)

When invoking ldumpstack with an argument specifying a Lua state, the above error is thrown.
>lval 0x400017f8
No global L located (tried globalL and ngx_cycle)
Similarly, invoking lval with any value without a findable global state results in an error, and lval does not accept a second argument to specify a state to look in.
lval checks for a global state, but does not appear to use the result. Removing this check does not appear to break anything, but does make both of the above cases work as expected.
lgcstat doesn't work with latest LuaJIT
When I try to use lgcstat, gdb raises an exception, says '没有名为 ptr32 的成员'.
After some debug works, I find the exception is raised from this line: https://github.com/openresty/openresty-gdb-utils/blob/master/luajit21.py#L2549. Some changes of LuaJIT have broken the command.
So I dig inside the LuaJIT, and figure out several interesting things.
This commit: openresty/luajit2@cfa188f, renamed k64 to k64p, which caused the break directly.
However, the another one: openresty/luajit2@9e99ccc, removed k64p out of the code.
I know little about the inside of LuaJIT, so I am not sure how to adapt the change.
Could you fix the problem?
no support for gc64?
When I try to use this with gc64 I get this:
(gdb) lbt
Python Exception <class 'gdb.error'> There is no member named ptr32.:
Error occurred in Python command: There is no member named ptr32.
Error occurred in Python command: No frame selected
I am new to linux and nginx and I am trying to use 'nginx-gdb-utils' to analyze luajit, and getting the following error while executing the gdb commands.
(gdb) lbt full

Can you please help me to identify the issue.
