    <p>So I'm attempting to use libopus on my native code for an Android application. My Android.mk file looks like this:</p> <pre><code>PLATFORM_PREFIX := /opt/android-ext/ LOCAL_PATH := $(PLATFORM_PREFIX)/lib include $(CLEAR_VARS) LOCAL_MODULE := libopus LOCAL_SRC_FILES := libopus.a include $(PREBUILT_STATIC_LIBRARY) # I have to redeclare LOCAL_PATH because the library is in /opt/android-ext/ # and my project is somewhere else. Not very elegant. LOCAL_PATH := /home/sergio/workspace/Project/jni include $(CLEAR_VARS) LOCAL_MODULE := opusUtilsNative LOCAL_SRC_FILES := opusUtilsNative.c LOCAL_C_INCLUDES += $(PLATFORM_PREFIX)/include LOCAL_STATIC_LIBRARIES := android_native_app_glue libopus include $(BUILD_SHARED_LIBRARY) </code></pre> <p>And my code in opusUtilsNative.c looks like this:</p> <pre><code>#include "opusUtilsNative.h" #include &lt;opus/opus.h&gt; #include &lt;opus/opus_types.h&gt; JNIEXPORT jbyteArray JNICALL Java_Project_OpusUtils_encode (JNIEnv * je, jclass jc, jbyteArray data){ int rc; opus_int16 * testOutBuffer; unsigned char* opusBuffer; OpusDecoder *dec; dec = opus_decoder_create(48000, 2, &amp;rc); return data; } </code></pre> <p>And when I try to build it, it works fine <strong>only if I remove the line that uses the "opus_decoder_create" function</strong>. Else I will get this:</p> <pre><code>error: undefined reference to 'opus_decoder_create' </code></pre> <p>I can see that opus_decoder_create is clearly defined on opus.h, which is clearly being included since if I exclude that line, I'll get an error regarding the opus_int16 and OpusDecoder declarations. How come some definitions are being included and some aren't?</p> <p>Any help will be greatly appreciated.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
