Ok, so I noticed on Ryzom Forge to make plushies, etc, you need 3ds max, Well, i went to the web page and it looks like its a Windows program. I use a mac, is there an equivelent program you can use for OSX? I would like to learn this :D

You MIGHT be able to use blender - the ryzom core people were trying to convert everything for blender but you'll have to ask them first if they are done with everything related to making it possible to use blender instead of 3Ds max and if they are what to keep in mind

And today on #ryzom :

13:00:41 rdelvax | Hi,
13:01:07 rdelvax | Is there anyone who charted the shape, skel and anim files?
13:02:42 rdelvax | If so, I could try and learn enough python to try and make blender importer/exporter plugins with a little help from some friends...
13:03:57 rdelvax | If there's no info for those filetypes, I might give reversed engineering a try, but that could take a while...
14:33:49 dfighter | rdelvax, as far as I know there's already an ongoing effort
14:34:10 dfighter | you should consult with Botanic_
14:35:51 sfb | rdelvax: If you want to know what is in the files you need to look at the serialization methods for the corresponding classes.
14:36:13 sfb | rdelvax: Because these file formats are binary representations of the contents of an instance of those classes.
14:36:49 sfb | rdelvax: Regarding a Blender plugin, dfighter is spot on. Botanic_ and someone else have been working on something on the side. It'd be worth talking to him to see where it is at.
14:39:42 rdelvax | thnx, I'll contact botanic ;)
14:40:07 rdelvax | Maybe I can help him.

I have been attempting to make a working build for 2 days now, and am at a complete loss for what else to try.

I have successfully compiled the client about 10 different ways and tried the branches develop, compatibility, compat-dev. and default all with the same results. I can login and select my character, the loading sequence goes for a short ways and then the client crashes.

Some details on the error are:

A fatal error occurs. The program must quit

In compiling I found that the luabind library requires lua5.2, so I explicitly selected that version of lua from the 2 versions that are installed on my system. Not making that selection had the same results.

No combination of static or dynamic linking choices about lua and luabind have made a difference. I took to manually editing the link.txt file to control the static/dynamic linkage of each system library.

I have had to build curl, libxml2, and openal from source code in order to get them to behave properly.

Can anyone suggest anything else to try? Do I have to build my own lua and luabind; or maybe the error has nothing to do with lua?!

There should be more detailed error before that line in log file.

There is a lot of stuff in between the parts I already posted. Most of it seems to match logging generated by a working executable, specifically the one found here.

The only other lines that appear to have potential relevance are:

2015/08/02 21:49:56 <Unknown> INF e689a740 common.cpp 615 : Exception will be launched: interaction.lua:134: attempt to call field 'mod' (a nil value)

have you updated ryzom files using ryzom_update.sh script? it also overwrites ryzom_client binary, so you need to restore it if your own compiled version is named the same

I placed Icus's executable and mine in the same location where the original 32bit client had been extracted. I ran each and compared the logs. There were no updates in between that comparison.

There should be ryzom_update.sh script.

If it's missing, then this is what it contains

rsync -rtzv --progress --stats www.ryzom.com::ryzom ./

I think we are failing to communicate here.

My system is a nice new Debian 8.1 (Jessie) amd64. It can not run the 32 bit ryzom binary that the ryzom_update.sh pulls.

I built close to 30 different binary configurations involving controlling specific library versions, combinations of static/dynamic linking, and 4 different branches of ryzomcore. They ALL crashed at the same place with the same message.

I tried the binary posted by Icus that I referenced earlier and it ran fine.

The problem is something difference in how I am building the binaries or specific libraries and that is what I am looking for help on.

Did it, got more files patched when I ran a ryzom binary. My build still crashes at the same loading step. This time it didn't output the fancy nel_log with all the extra data. I compared log.log for runs by my current build and Icus's and found they were the same up to the crash. The last messages in the crashing log are different than before the update:

2015/08/03 07:18:30 WRN 2029074240 <Unknown> path.cpp 579 lookup : PATH: File (r2_entry_points.txt) not found (r2_entry_points.txt)

2029074240 <Unknown> path.cpp 579 lookup : PATH: File (r2_entry_points.txt) not found (r2_entry_points.txt)

You running binary from 'default' branch it seems.

I believe creating empty file with that name under 'user' directory should get thru that error. 'compatibility' branch (and ryzom files) has that file named as 'ring_map_entry_ponts.txt'

That binary was built from the "develop" branch. Specifically by downloading the source at https://bitbucket.org/ryzom/ryzomcore/get/5c9146c667c1.zip

The problem is most likely a memory corruption caused by different library builds having a sizing difference.

I have since managed to stick another monkey wrench into this system. It always happens when I am working with a new system. So I can't build anything else for testing until I go through reinstalling all of it. See you in a few days.

If you create an empty file called r2_entry_points.txt in the ryzom/user directory, that problem will go away.

Karu was right about the problem being the branch I had selected. I was able to get the "compatibilty" branch to build in my new setup and it ran correctly. I then spent some time researching the differences and was able to build from nimetu's fork with the compatibilty changes manually merged.

That combination gives me a nice snappy client without the libwww crap. I reduced the dynamic libraries down to just a few that would seem to be present on any linux system. The size is a bit smaller than Icus's build which seemed to be from the same fork and merge method. I would attribute that to building all the libraries for it from scratch with options that remove extra sections. There are even a few more protocols I could eliminate from libcurl.

After I spend a fair bit of time testing it in game I will post a full shell script to get and build everything.

There is compatibility-develop branch that tracks develop more closely and has libwww removed.
