lua http installation failing with lua 5.3

[atibdialpad]

This is probably not a bug/ some mistake on my side, still reporting if someone can clarify
Steps :

1. Install lua 5.3 : apt-get install lua5.3

2. Install luarocks : apt-get install luarocks

3. Install lua-http FAILS

4. Install Lua 5.1

5. Install lua http SUCCEEDS though I get some WARNINGS
   Warning: /usr/local/lib/lua/5.1/compat53/table.so is not tracked by this installation of LuaRocks.

6. My example http_lua code works

@daurnimator any ideas/suggestions what might be going wrong here ?

Hi,

I think you need to install liblua5.3-dev to get the header files. sudo apt install liblua5.3-dev.

The reason it works for Lua5.1 is because the LuaRocks installation pull in liblua5.1-dev files.

[daurnimator]

@atibdialpad as Russell notes; you need lua headers installed. on debian based distros you can usually find them in the liblua5.x-dev package for your lua version.

Thanks @daurnimator and @RussellHaley, Will try that and get back.
Actually I am trying to use lua-http as part of a vector pipeline https://vector.dev/docs/reference/configuration/transforms/lua/ , probably need to find where Vector is installing lua and make the http-lua installation available to it.

Thanks Guys. This helped me solve the installation problem. Though my original pblm still exists which I am tracking here vectordotdev/vector#7299
Thanks for the help.
