Hi,
I get following linker errors when compiling the useplugins example with:
[code:1anxuybg]

I just wrote an output-plugin for windows and it works properly. I wanted to port it to Linux as well. Unfortunately, it’s not loaded. I assume I can just load output-plugins with the "p"-version of the fmodex. On windows it works in both versions.
I link the output plugin like this:
[code:1anxuybg]
g++ -shared -fPIC -o output_plugin.so -I"../../../fmodapi400linux/api/inc" ../../src/output_plugin/main.c
[/code:1anxuybg]

Hi,
my output plugin is now working fine I found a minor bug in the fmod_output header file:
the function FMOD_OUTPUT_INITCALLBACK is defined under windows as follows:
[code:rzy01j6s]
typedef FMOD_RESULT (F_CALLBACK *FMOD_OUTPUT_INITCALLBACK) (FMOD_OUTPUT_STATE *output_state, int selecteddriver, FMOD_INITFLAGS flags, int *outputrate, int outputchannels, FMOD_SOUND_FORMAT *outputformat, int dspbufferlength, int dspnumbuffers, const void *extradriverdata);
[/code:rzy01j6s]
and on linux and macosx:
[code:rzy01j6s]
typedef FMOD_RESULT (F_CALLBACK *FMOD_OUTPUT_INITCALLBACK) (FMOD_OUTPUT_STATE *output_state, int selecteddriver, FMOD_INITFLAGS flags, int *outputrate, int outputchannels, FMOD_SOUND_FORMAT *outputformat, int dspbufferlength, int dspnumbuffers, void *extradriverdata);
[/code:rzy01j6s]
The "const" for extradriverdata is missing, therefor my code might not be entirely compatible and only gcc4 on MacOSX was complaining about this.

I think you may have an old version header for your win32 build The const for the extradriverdata shouldn’t be there anymore.

Hi chenpo,
thank you, you are right. It was version 30 on windows.
