NWNX Ruby

[Hialmar]

Are you using my version or the one in the trunk ?

My version doesn't work yet.
I have never managed to get it running right.

It should be the good one then.

What version of ruby do you use it with ?

Edit: If you don't use a 1.9 ruby (which doesn't work with the current version of xp_ruby) you might need to add this at the beginning of your file:

You're right, the load path isn't being setup properly by the ruby plugin - appears to be a bug in ruby_init_loadpath(); with the library used to compile the nwnx plugin.

Using something like this (in a file called preload.rb) to set it up manually:

[Dethia]

I have been working with elven on this, he has been helping me try to set up xp_ruby with no luck.

Things are as he mentions above with two additional pieces of information.

When things are ran with the above load rb file nwnx server gives the following error:


"Unable to find msvcrt-ruby18.dll"

If I add this dll into the default atari folder, the server then simply crashes. (it found the dll and whatever is supposed to happen after causes the crash).

Precie error is:

[Dethia]

Through elven I got some information from Virusman on possibly missing some dependency files (?)

I ran dependency walker on the msvcrt-ruby18.dll and am missing 2 dll files

wer.dll
ieshims.dll

i will try to get those two but this stuff is really above my head so if anyone is actually using nwnx_ruby on their server and wouldn't mind writing a set-up guide I'd appreciate it. It'd be a shame if this tool works and no one is using it.

--Well I used dependency walker to find all missing dll's and have now added them, sadly the problem persists. The main issue is I do not know how to point xp_ruby to its main dir from w

--Oh the crash report for nwn2 is as follows:

[virusman]

msvcrt-ruby18.dll build date is half a year later than xp_ruby.dll build date.
It's probably compiled with a different compiler.
It seems like you're running Ruby 1.8.7. xp_ruby was linked with 1.8.6, and it's not compatible with 1.8.7 since Ruby developers changed the compiler.

Try this version (xp_ruby linked with Ruby 1.8.7):

I am running ruby 1.8.6-389 I believe but I will try to get an earlier version.

With the 2 dll's you provided, if I just use the msvcrt-ruby18.dll, i still get the crashing. If I use the xp_ruby.dll you provided NWserver never runs (doesn't start) and neither does nwn2server.exe.

--I installed version 1.8.6 -25. The crashing no longer occurs, but I end up with the same old error as I had originally.

[Hialmar]

Maybe it would be better linking with the static library instead of the dynamic one.

That's what I did with the 1.9 version. However this never worked so I'm not sure it will help you either.

Personally I'll try to port the ICE plugin and try to use either java or ruby if I can find a way to code a server version for ICE (or use it with the client only provided version). But that's another story.

*nods* Thanks for the heads-up.

I'm also more familiar with java so this would help me a lot.

The most recent code is available here. This is already forward-ported to the 2.8 branch of nwnx2 (with inter-plugin messaging system) to use resman for native SCO/RCO im/export inside the JVM.

There's a few ruby scripts that generate the native-libs and sources, and also most of the exported constants.

If you have any questions, don't hesitate to ask.

[Hialmar]

Just a note that I have managed to have ruby working with NWNX4 using the NWNX2 JVM plugin from Elven that I ported to NWNX4 and JRuby (a JVM implementation of Ruby).
JRuby is supposed to be compatible with the 1.9.1 version of Ruby.

Details are here:

FYI, there's a leak in nwnx_ruby as-is in that StackPopString needs to free the contents of the CExoString it gets back from CVirtualMachine::StackPopString. The memory must be freed to the NWN2 heap and can't be released with "free" or "delete". This will cause the plugin to leak memory every time a script function that returns a string is called by Ruby code.
