lua-resty-core warning message

[Soojin Nam]

Hi,

I have installed OpenResty 1.5.12.1 RC3  and initiated lua-resty-core in nginx.conf.

    http {
        init_by_lua '
            require "resty.core"
        ';
        ...
    }

I got warning message.

nginx: [warn] [lua] base.lua:27: use of lua-resty-core with LuaJIT 2.0 is not recommended; use LuaJIT 2.1+ instead

How can I fix the warning?

Thank you.

Regards,

jsunam

Are you sure you're using the stock version of OpenResty 1.5.12.1 RC3?

This version of OpenResty includes LuaJIT 2.1 by default and this
warning indicates that you're using some other nginx linked with
LuaJIT 2.0. Please check your OpenResty installation and nginx startup
scripts.

When I built openresty 1.5.12.1 rc3, there were the following two lines in my .bashrc file.

export LUA_PATH="$LUA_PATH;/usr/local/share/luajit-2.0.3/?.lua;blah blah;;
export LUA_CPATH="$LUA_CPATH;/usr/local/share/luajit-2.0.3/?.so;;blah blah;;

I removed "/usr/local/share/luajit-2.0.3/?.{lua, so} " and rebuild openresty and started nignx.

I got no warning message.

Thank you.

On OSX and if I have LuaJIT installed (say with brew), and I build the OpenResty with:

./configure --with-cc-opt="-I/usr/local/include" --with-ld-opt="-L/usr/local/lib"

make

make install

I do get this same error. If I uninstall luajit with brew, everything is fine then. Is it by design, that the build process uses the OS installed version of LuaJIT, and if there is no LuaJIT found on a system, it reverts to the bundled one?

Regards

Aapo

No. The expected behavior should be always using the bundled one
unless the user specifies --with-luajit=PATH to point to another
LuaJIT installation location.

It seems like your -L/usr/ocal/lib overrides ngx_lua's -L option set
from the LUAJIT_LIB environment (set by OpenResty's ./configure).

Will you try applying the patch at the end of this mail to your
bundle/ngx_lua-*/ and try it again (from ./configure)

Thanks for the report!

Hi,

I applied the patch, and recompiled:

./configure --with-cc-opt="-I/usr/local/include" --with-ld-opt="-L/usr/local/lib"
make
make install

And got the same error:

nginx: [warn] [lua] base.lua:27: use of lua-resty-core with LuaJIT 2.0 is not recommended; use LuaJIT 2.1+ instead

I tried omitting the --with-ld-opt="-L/usr/local/lib" but that leads to a compile error:

Undefined symbols for architecture x86_64:
  "_pcre_free_study", referenced from:
      _ngx_http_lua_ngx_re_gmatch in ngx_http_lua_regex.o
      _ngx_http_lua_ffi_compile_regex in ngx_http_lua_regex.o
      _ngx_http_lua_ffi_destroy_regex in ngx_http_lua_regex.o
      _ngx_http_lua_ngx_re_sub_helper in ngx_http_lua_regex.o

      ...
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [objs/nginx] Error 1
make[1]: *** [build] Error 2
make: *** [all] Error 2

So, that argument is obviously needed on OSX.

I know how to overcome this, but I'm sure someone else will hit this as well. I have tried this with two Macs (on with a lot of history) and other with clean installed Maverics with only brew installed luajit. The same problem does not arise if I install LuaJIT with Rudix.

Hmm, this is strange. Will you paste the full output of your
"./configure" and "make" commands somewhere like gist?

Also, after "make install", please run the following command and
provide the output:

otool -L /path/to/your/openresty/nginx/sbin/nginx

Thanks for looking into this!

Yes, many Mac OS X systems have multiple PCRE installations at the
same time and here you're using a new version of PCRE's C headers
while trying to link against an older version of PCRE's lib.

Thanks for the details! I've reproduced the issue on my macbook and
fixed it in the following pre-release tarball:

http://openresty.org/download/ngx_openresty-1.7.4.1rc1.3.tar.gz

Please try it out on your side :)

Thanks!
