Title: sfml-audio-d.lib causes openal32.dll error
Post by: jerryd on May 05, 2013, 07:34:48 am

SFML forum,
 SFML1.6   Visual C++ 2010

 I'm putting sounds in a working program for the first time.

 My code compiles OK if I put sfml-audio-d.dll in
 Linker > Input > Additional Dependencies.

 But then when I run it I get the error:
 This application has failed to start because openal32.dll was not found.

 I have tried #include <path to the openal.dll file>
 but then I get a whole screen full of errors when compiling.
 I also get a Microsoft Package Server error window saying
 "Micorsoft(R) Visual C++ Package Server has encounted a problem
 and needs to close".

 I have other programs running OK but without any sound code.

 I have read a few web sites about openal32.dll but couldn't
 find a solution for this.

 Any Suggestions?

openal32.dll is one of the two additional shared libraries one needs (the other being libsndfile-1.dll) to include in the same directory as your exe in order to use the audio module.

Both of these are in a folder called extlibs that is included with your SFML download.

 I have tried #include <path to the openal.dll file>

#include is for code files only. :P

You should use SFML 2 and learn how to use your development tools, as well as read up on the topic of libraries. ;)

SFML forum,
 Thanks for the replies.

 Here are the only 2 lines in my program about sound.
        sf::SoundBuffer Beep;
   if (!Beep.LoadFromFile("beep-1.wav")) return EXIT_FAILURE;

 I put "openal32.dll" and libsndfile-1.dll" in the folder
 with the .exe file and made a lot of progress.  Now I can
 compile without errors and when I run I get a different
 Microsoft error saying:

 Unhandled exception at 0x78061174 (msvcp100.dll) in MatchMeSFML.exe:
 0xC0000005: Access violation reading location 0x00133000.

 If I comment out those 2 lines the error goes away and the
 programs runs fine.

 Can't find any information about this message on the net.

UPDATE:
 I've concluded that the line that causes the Microsoft error is:
 if (!Beep1.LoadFromFile("beep-1.wav"))

 I can play this .wav file in a media player so I think it's OK.
