I'm trying to compile raudio on it's own for a CLI based game, but I am getting a lot of undefined references, which tells me it's a linker problem.

I have tried to compile raudio.c into an object file, compile my main.cpp file into main.o and from there compile them together. I also tried to it all in one swoop with g++ main.cpp include/raudio.c -I include/ -I include/external -DRAUDIO_STANDALONE -DSUPPORT_FILEFORMAT_WAV

I also noticed that when I did -DRAUDIO_STANDALONE, I had to comment out the definition in raudio.h otherwise I would get a redefinition error, but if I didn't do DRAUDIO_STANDALONE and I left the definition in raudio.h, it would look for raylib.h.

I'm sure this is a big case of my just know enough to case damage.

I identified a possible bug with the AAudio backend for miniaudio in which an assertion from miniaudio fails when the user leaves and comes back to the app.

Miniaudio issue: https://github.com/dr-soft/miniaudio/issues/103

For now, I suggest this fix, a simple #ifdef that initializes miniaudio with the OpenSL|ES backend on Android since from my tests the OpenSL|ES backend doesn't have this issue.

Problem description

When compiling the library example (es. raudio_standalone.c) in standalone mode, a lot of "Undefined reference" errors pop-up.

Solution

By changing the raudio.c precompiler #if guard from

#if defined(SUPPORT_MODULE_RAUDIO)

to

#if defined(SUPPORT_MODULE_RAUDIO) || defined(RAUDIO_STANDALONE)

the issue seems to be fixed.

Also, to properly compile the library, some raudio.h definitions were updated, in particular:

• The bool definition was aligned to the current definition in raylib.h;
• The AudioCallbackdefinition was added;
• The rAudioProcessor definition was added.

Should Fix

If I understood the problem correctly, this pull request should also fix issue #5.

P.s. Apologies for the "precompiler" typo in the commit message, it should be "preprocessor"... 😵‍💫

Problem

During compilation with flac support the following error appears:

D:\raudio\raudio\src\raudio.c: In function 'UpdateMusicStream':
[build] D:\raudio\raudio\src\raudio.c:1791:69: error: 'frameCountToStream' undeclared (first use in this function); did you mean 'framesToStream'?

It is caused probably by omitted variable change for SUPPORT_FILEFORMAT_FLAC case in UpdateMusicStream(). It was introduced in c3efa2cda425132f253e0da9ffeb1708dd17eaaa.

Solution

I renamed variables to the existing ones (I could not find frameCountToStream or AUDIO.System.pcm anywhere). My formatter also removed some trailing whitespaces ;)

There's also warning: "RAUDIO_STANDALONE" redefined when defining the variable with compilation flag, I guess it can be wrapped in #ifndef in this case. I didn't add it in this PR, though.

Let me know if it's alright to merge this or there are some changes to be made
