nginx with static library

itspuneet59

Hello,

I am using nginx and willing to link .lua files as library.

I followed Mike's guide for creating a static library

http://stackoverflow.com/questions/11317269/how-to-compile-lua-scripts-into-a-single-executable-while-still-gaining-the-fas

But when I run configure on openresty, it does not work. I have library platform.a in /tmp/files directory

./configure --with-luajit --sbin-path=/usr/sbin --pid-path=/var/run/nginx.pid -j2 --with-http_stub_status_module --with-ld-opt='-Wl,-E -L/tmp/files -lplatform

Can someone help me in getting this work?

Also, in the config I was using content_by_lua_file 'abc.lua'

How will that look when I have a static library compiled?

The code in lua file gets changed frequently, is there an option of doing the same with dynamic libraries?

Thanks

Puneet

Hello,

I am able to link nginx with a static library made up from lua files.

Can somebody please guide me, how can I create a xyz.so for lua code using luajit and make nginx link with that library ?

Thanks and Regards

Puneet

Please read the official documentation of ngx_lua on this topic:

Your command is wrong. Please follow the documentation.

Also, try always providing details instead of simply saying "it does
not work", which is not really helpful for diagnostics, unfortunately.

This technique only affects Lua module files that are loaded by
require(). This is also documented in the link above.

I don't think LuaJIT supports this. You can ask on the official luajit
mailing list for such features instead.

agentzh,

I've wondered about this method for awhile now. I've got some things that I'd like to package with the executable but my build suffers from a 'chick or the egg' scenario. In the case of openresty, ./configure builds luajit up front but I need the produced luajit binary to generate bytecode. Unfortunately, this causes a situation where I need to configure openresty twice. This is sub-optimal for build automation. I have the same issue with luarocks. In my build harness I would like to package luarocks with openresty but there are problems with the interpreter not being present. This causes a lot of manual work. Do you have any advice to overcome this issue?

I was thinking it may be possible to add a secondary script or a switch to configure to only generate the luajit build without configuring openresty.

I wish there was a Lua equivalent of perl's PAR::Packer (http://search.cpan.org/~rschupp/PAR-Packer-1.024/lib/PAR/Packer.pm) to pull in peripheral dependencies. If I could, I would bundle modules I need that are painful to install. Luasec for example is required for luarocks to pull source from 'https' links but does a terrible job at detecting libssl paths.

On a side note, I've always wondered why you don't want your nick name capitalized?

Yeah sure. Patches welcome :)

Yeah, I was also a PAR::Packer user. We could have something similar
for OpenResty :) Because my time is always limited, you're always
welcome to contribute ideas and even implementations :)

Thanks!
