i'm new to mupen64. i've just downloaded and untarred it. when i try to run it it can't load its plugins and so the plugin selection boxes are greyed out. in the terminal window it gives permission denied errors:

The best thing you can do delete the folder. and untar with you normal user again

ciu

 

[tremby]

i did untar as my normal user. as you can see, the owner of the files is tremby, not root.

i should say that i'm using fedora core 6 and gnome.

 

[GarulfoLinux]

chmod +R 777 mupen64-0.5/

 

[tremby]

i assume you mean -R rather than +R. i gave all the files full permissions and get the same error messages.

 

[GarulfoLinux]

yes excuse me it's " -R " of course! ^^

i found the problem:

I was having this problem but a quick google search revealed it was SELinux. Sure enough, setting it to Disabled or Permissive elimated any errors. I dont really know what im doing so i dont know what exactly in SELinux is causing the problem. But just disable it for a temporary solution.

I had the same problem. I solved it by setting the security context of the .so files to be the same as some other .so files in my system. In mupen64-0.5/plugins/, I have a bunch of .so files. I fix their security context by running "chcon -t textrel_shlib_t mupen64-0.5/plugins/*.so".
