#713 SDL port segfaults when openGL and scalers enabled

[Eugene]

Linux Mint 17.2 / Core i7-2600K integrated GMA HD3000.
if "special scaler = none" all works good, but if you select any filter fceux will crash.

Does this occur with openGL disabled? The SDL scalers have never worked with openGL as far as I know. That being said, the sdl port should handle this better and show an error message stating that scalers are not supported with openGL instead of segfaulting

[Eugene]

Does this occur with openGL disabled?
No, but sometimes i have segfault when trying NTSC-filter.
And emulator GUI is also broke when change filters.

use irc https://webchat.freenode.net/ not icq
channel #fceu

[Lukas Sabota]

prevention has been added in r3173 that should prevent opengl/scalers from running and segfaulting, but i will leave this bug open to investigate your other issues

[Eugene]

Can i write here about all linux bugs that i've found?
Okay,
1. fceux-sdl looks for palettes in "/usr/share/fceux/palettes" by default,
but can't do the same for luascripts in "/usr/share/fceux/luaScripts"
2. lastest fceux don't compile on old ubuntu 10.04 EVEN when i disable all stuff (OpenGL, GTK UI, Movies etc) in SConstruct file. Since 2.2.2 compiled good.
If you're interesting, i'll give you logs.

[Lukas Sabota]

1. Are you referring to the GUI here?
2. Please post logs of the compilation issue and the sconstruct options

[Lukas Sabota]

1. I think you're referring to the open file dialog for luascripts - this is fixed in r3174.

[Eugene]

1. Yes, i mean GUI.
2. http://savepic.su/6097524.png - ubuntu 10.04 - all stuff disabled:

Ubuntu 10.04 comes with a really old version of GTK that does not include GTK methods used in recent fceux versions. For 10.04 you can either install an updated version of gtk (probably a pain), use the fceux ubuntu package in 10.04, or upgrade ubuntu
