Bug also effects sdl 2.02

Another way to trigger this bug is the refresh button in the controller settings.

Doesn't look like upstream are rushing to fix this. We might need a work around for this.

(Maybe as simple as disabling haptic support in dolphin if sdl 2.02 or 2.03 is detected.)

Fixed upstream. No stable release yet, so Dolphin could still use a workaround.

IT sounds like the sdl project is looking at a 2.0.4 release. I'm assuming that that will fix this issue. http://forums.libsdl.org/viewtopic.php?t=10532 Could still be a while before that is released and gets into ubuntu.

I installed the version that's posted in the link, and it doesn't seem to fix the issue. I think it's strange because it should've been fixed upstream already :/

this issue no longer occurs for me in latest mater (4.0-4843). i can refresh my controller inputs in config and close and start multiple games in one session without the emulator crashing now. this is using Ubuntu 14.10 and a dualshock 3 controller.

This is still an issue for me with sdl2.0.3 on 5099 using the 2 port mayflash adaptor. (Archlinux)

I'm having this issue in both ubuntu 14.04 and 14.10 (4.0-5456). @guitaris, had you tested with newer version?

Problem solved for me.

It happened last time in 5100, after building and installing 5474 it was solved.

I use an up-to-date debian Sid:
libsdl1.2-dev 1.2.15-10+b1
libsdl2-dev 2.0.2+dfsg1-6

As there is still no 2.0.4 release upstream (and some OS releases will never upgrade to it, this needs a workaround.

The current work around I'm using is the mercurial dev build.
https://www.libsdl.org/hg.php

This works as far back as 4.0-652 (as far back a build I use) and still works in the latest master I tried 4.0-5734.

I'm using Linux Mint 17.1 and Mayflash 2 port GC adapter

Well my work-around(mercurial dev build) now appears to have been breaking netplay for any build starting with 4.0-5681 and SDL 2.0.2 works fine with 4.0-5886 (didn't test anything earlier).

A (crappy) workaround is to add this to any source file of dolphin:

#include <dlfcn.h>
static int (*real_strcmp)(const char *str1, const char *str2);
extern "C" int strcmp(const char *str1, const char *str2)
{
if (str1 == NULL)
return str2 == NULL ? 0 : 1;
else if (str2 == NULL)
return -1;

if (!real_strcmp)
real_strcmp = (int (*)(const char *str1, const char *str2)) dlsym(RTLD_NEXT, "strcmp");
return real_strcmp(str1, str2);
}

It's not the worst workaround I've seen...

You could be a bit less crappy and actually implement strcmp, instead of praying it's exported by something else and crashing when it's not.

  • Status changed from New to Work started

Rather than do anything crazy like overriding strcmp, disabling rumble or statically building sdl into dolphin; I'm going to remove SDL and replace it with a evdev based input backend.

SDL is more or less just a thin wrapper around evdev anyway.
