我正在尝试使用android-NDK编译Speex for Android，目前我的目标是Android 2.3.3但是后来我将在所有大于1.6的Android版本上测试我的应用程序。我的Android.mk文件如下所示： -

include $(CLEAR_VARS)
LOCAL_MODULE := libspeex
LOCAL_CFLAGS = -DFLOATING_POINT -DUSE_KISS_FFT -DEXPORT="" -UHAVE_CONFIG_H
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include

问题出在我的代码的某些方面我需要 FLOATING_POINT 配置，但是代码只有在我将其更改为FIXED_POINT时才有效，否则线程不会得到CPU周期（一个线程占用大部分CPU周期，即程序在该线程内的浮动算术中挂起）我如何让FLOATING_POINT为我工作？
