Hi, in my pc when i start my allegro program it crash with segmentation fault when i call the allegro function "al_reserve_function(1);". In other pc it doesn't happen then i have read the code of this function and it crash when try it "if(_al_kcm_driver->allocate_voice(voice) != 0)" then the problem can be caused by the audio driver. How i can check this? I have Ubuntu 14.04 and i use codeblocks. Thanks. |

Do you call al_install_audio properly and check it's return value before calling al_reserve_samples? If al_install_audio returns false for some reason, you can't use any audio functions. |

Do you compile Allegro yourself? You could paste a copy of the make output here, perhaps that will bring more clarity... |

I assume audio otherwise works correctly on that computer? Could you try the audio-related Allegro examples and see if they work or not? If not, it may be an Allegro bug. |

Try setting the default mixer BEFORE reserving samples, something like: al_set_default_mixer(mixer);

The problem is the al_install_audio(), it return always false also in a simple project. |

beoran said: Do you compile Allegro yourself? This is the important question to be answered. Ubuntu is basically the best supported platform for Allegro, so it all should just work assuming Allegro was built/installed properly. EDIT: I should also say, that for starting, I'd recommend using our PPA: https://wiki.allegro.cc/index.php?title=Install_Allegro_from_Ubuntu_PPAs "For in much wisdom is much grief: and he that increases knowledge increases sorrow."-Ecclesiastes 1:18 |

Most likely is was a driver problem then? Too bad we couldn't figure it out. But anyway, good to hear it works for you now. |
