libretro-fceu.so is segfaulting. there's a bug in the emulator, but I don't know why it would be affecting the other roms. I'll download fceu and do some tests

I'm re-doing the add-on repo, adding a bit more infrastructure by making most of the emulator add-on "fluff" auto-generated. I'll be able to compile and upload new versions weekly by simply changing two or three lines in an xml file, versus the whole add-on repacking process (which I had already partially mechanized). The frequency of updates will even make feedback more useful for those awesome people developing these emulators. Crashes, like this one, may soon be slightly less common.

It's not just that one emulator but all that segfault I just clipped that one as an example. Also I'm running 32bit linux.

Code:
Aug 14 19:03:30 kernel: [609745.057015] xbmc.bin[8045]: segfault at 0 ip a5e006a3 sp bff20d60 error 4 in libretro-snes9x-next.so[a5c32000+205000]

Aug 14 19:09:23 kernel: [610097.661756] xbmc.bin[8714]: segfault at 0 ip a5bff6c4 sp bfb1f380 error 4 in libretro-fceu.so[a5bfb000+90000]

It also segfaults just installing the emulators

**garbear** · 2013-08-15, 22:26

drivesoslow, can you try older versions of the emulators? They're available here: https://github.com/garbear/repository.li...32/release

I uploaded freshly compiled 32-bit versions on 2013/07/10, so maybe all the new versions have a problem with the libretro ABI.

I reverted back to 1.0.2 with no luck. I'm deleting my local repo and I'm cloning from scratch to see if something has got into my build tree.

UPDATE

I cloned a fresh copy of the repo and built it from scratch. I no longer get a segfault but XBMC still crashes whenever I try to load a rom.

Thanks for the debug log. The most recent commit should fix the crash.

Pulled the changes and rebuilt but it still crashes with a slightly different error:

http://pastebin.com/xRYnxPpQ

I also compiled the latest 32bit emulators and posted them here if you'd like to update your repo: https://dl.dropboxusercontent.com/u/1521...-32bit.zip

The error now is a red herring, a placeholder for when I actually defined variables. Right after the "error", RetroPlayer loads the game and that's where the crash is occurring. I tried with FCEU and had mixed success:

win32: 0.98.13 uploaded 2013-02-16: worked
win32: 0.98.14 uploaded 2013-04-23: crashed
win32: 0.98.15 uploaded 2013-08-09: crashed
linux: 0.98.13 uploaded 2013-02-16: worked

I recently re-structured the add-on repo, all FCEU versions are now available here: https://github.com/garbear/repository.li...er/release

My compile jobs failed last time I tried libretro-super script on linux x64. I've reformatted since then, so I'll give it another go. If I can get the most recent version to compile and crash, I'll try pulling it up in the debugger and seeing if I can track down the problem.

EDIT: I found the problem, I'm asking Squarepusher about it now

Thanks, I'll get those updated. I also need the date of the last commit, as I use this in the changelog and it helps give a sense of when the last update was. The script I wrote is: list-rev.sh. I just ran the script, so I don't need the dates this time.

EDIT: And make sure to do a fresh pull on libretro-super, they shuffle stuff around pretty often and it's good to keep all platforms in sync with the latest libretro-super.

The emulator repo, https://github.com/garbear/repository.libretro, has just been re-structured and is now mostly generated from a python script. Updating the add-ons is as simple as creating a new version folder e.g. 0.98.15, copying the .so and creating a meta.xml file. A sample meta.xml folder (currently) is:

Code:
<meta>

    <date>2013-07-10</date>

    <extensions>fds|nes|unif|zip</extensions>

    <pretty_version>v0.98.13mm (SVN)</pretty_version>

    <allowvfs>false</allowvfs>

    <blockextract>false</blockextract>

    <changelog>Updated to 26a2579 @ 2013-05-19</changelog>

</meta>

Most of the time, the meta.xml file is just copied from a previous version changing the date and changelog to whatever list-rev.sh spits out. If the other fields need to be changed (they very rarely do), XBMC will fail to load the .so and explain the correct value in the debug log, so it's pretty to catch stale info.

Submitting a PR to repository.libretro.git should now be an easy (and easily-reviewable) way to update the repo if anyone wants to contribute freshly compiled versions.

The link I put up was pulled and built on the 16th. In the zip file there is a version.txt that returns the git version of each. I have this all automated so I will add your script to my batch so that next time you get a date stamp for each, but here is from my last build:

FCEU has been fixed in fceu-nex/66eb5fb

drivesoslow · 2013-08-18, 03:18

I updated the 32bit emulator libs:

https://dl.dropboxusercontent.com/u/1521...-32bit.zip

**garbear** · 2013-08-18, 05:18

Before I update those, I wanna make sure I didn't make any c/p errors with the current versions. drivesoslow, can you uninstall all your emus (and clear the addons/packages folder of gameclient.* zips) and then try installing all of the emulators from the repo in the add-on manager? If any have errors loading the DLL, upload your debug log and I'll fix them. Thanks! We'll probably repeat the process once I update the ones you just uploaded Smile

drivesoslow · 2013-08-18, 17:03

there were a bunch of emulators with error loading DLLs, and FCEU is listed as broken in the repo:

LostCosmonaut · 2013-08-20, 05:21

Where does the addons/packages folder live in Linux? I took an update and want to try getting a fresh install of the emulators

**garbear** · 2013-08-20, 05:42

go to userdata, then go one directory up. on OpenELEC, I have a /storage/.xbmc/userdata directory and a /storage/.xbmc/addons/packages directory.

linux32 emulators are broken until I get some time to update the repo, but linux and win32 work for me.
