[opus] about speech/music detector in opus 1.3.1

I’m wondering how can I get the speech/music classification result when encoding the audio in opus 1.3.1?
I found in the file opus_encoder.c, there is a opus_encoder_ctl request as OPUS_GET_VOICE_RATIO_REQUEST, so I wrote in my program the below code:
#define OPUS_GET_VOICE_RATIO(x) 11019, __opus_check_int_ptr(x)
LOGI("voice ratio:%d", voiceRatio);
But it always return -1.
And then I found that in the opus_encoder.c, the classification can only enable when #ifndef DISABLE_FLOAT_API, but I’m not sure if & where we define the DISABLE_FLOAT_API? How can I build the lib without this macro?
I build the lib for IOS, using the script at https://github.com/chrisballinger/Opus-iOS <https://github.com/chrisballinger/Opus-iOS>
It takes me several days to test but no success, can you help me?
Thank you very much!
