luasockets modeule will not load for me

[logan_number5]

A few months back I had tried unsuccessfully to get luasockets-2.0.2 to work in Celestia 1.5.1
from with ScriptedOrbits. Chris suggested not doing this and using hooks instead.
My problem then was an undefined symbol (lua_getmetatable) during the require ("socket") statement.

I've now returned to this problem and the hooks work great. but when I try to bring
in sockets.. I still get problems - and I've tried a dozen ways to fix it:

Error: error loading module 'socket' from file 'socket.so':
socket.so: cannot open shared object file: No such file or directory
Segmentation fault

Assuming that it was looking for core.so, I softlinked socket.so to core.so and
got my favorite message all over again:

Error: error loading module 'socket' from file '/usr/local/smallsat/luasocket/socket.so':
/usr/local/smallsat/luasocket/socket.so: undefined symbol: lua_getmetatable


How does everyone else define their LUA_PATH & LUA_CPATH vars?
Do you put lua and luasockets in competely separate dirs, or on top of each other?

logan_number5,

I also work with a hook script which connects to a socket.

To get the luasockets to work with Celestia you only have to copy the foldets mime, socket and (I think) lua into the celestia root directory and then it should work.
When you include the socket library by 'require "sockets" ' in your hook script you should be able to access the sockets from within Celestia.

Of course don't forget the SystemAccessPolicy which is one of my favourite mistakes.

hope this helps

Stuffer, I think it improved, but its not working. Thanks.

Error: error loading module 'socket.core' from file './socket/core.so':
./socket/core.so: undefined symbol: lua_getmetatable
Segmentation fault

I have a lua folder, a mime folder (one file), and a socket folder(one file).
The hook script, socket.lua, mime.lua are in the main celestia directory.

I compiled luasockets-2.0.2 against my Lua version is 5.1.4 -
and Lua has no .so files - only a liblua.a

Could it be that celestia's built-in Lua and mine are different, so luasocket fails
to load??

Michael,

I'm sorry.
I simply overread the first lines in your first thread.
You are using Celestia 1.5.1 where I switched to using Celestia 1.6 from SVN.

I can't think of anything why it doesn't work with your version. I would assume that sth has changed in the coding regarding the addition of new lua libraries. But I'm not into the code so far.

I could only recommend to try and use 1.6 where this seems to be extremely simple and with me works perfectly fine.

Alas, no joy with 1.6 either. Exactly the same error.

[foobar@yogurt ~/celestia-1.6]$ ./celestia
Cannot chdir to '/usr/local/share/celestia', probably due to improper installation
Error: error loading module 'socket.core' from file './socket/core.so':
./socket/core.so: undefined symbol: lua_getmetatable
Segmentation fault

Clearly, I have a serious configuration problem or I'm building
lua or luasockets incorrectly.

Thanks for all the suggestions Stuffer. I appreciate it.

But after struggling for a few months with this,
I'm going to surrender and go on to other things.

So I quit using my own build of lua-5.1.4 and had my system
folks install an official lua-5.1.4 and all worked great.

Not sure why that would matter, but it did.

Thanks again for your suggestions, Stuffer.

No problem.

Glad you figured this out.
Now have fun using it .
I think this socket thing is of great usage.
