Question

我正在尝试使用“android-ndk-r5b”为Android构建PocketSphinx。

我单独使用“pocketsphinxx”和“sphinxbase”项目从“https://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/PocketSphinxAndroidDemo”下载了PocketSphinxAndroidDemo项目。

我在Windows 7上使用Cygwin运行“ndk-build”问题是生成所有静态库（.a文件）但由于以下引用错误而无法创建.so文件：

$ /cygdrive/c/android-ndk-r5b/ndk-build
Gdbserver      : [arm-linux-androideabi-4.4.3] libs/armeabi/gdbserver
Gdbsetup       : libs/armeabi/gdb.setup

C:/eclipse/workspace/PocketSphinxAndroidDemo/obj/local/armeabi/libpocketsphinx.a

(pocketsphinx.o): In function `ps_add_word':
C:/eclipse/workspace/pocketsphinx/src/libpocketsphinx/pocketsphinx.c:565: undefi
ned reference to `ngram_model_add_word'

指定了所有头文件路径。创建静态库没有问题，但是链接静态库以创建共享库存在问题。

这是我的“Android.mk”文件：

提前感谢您的任何建议！ gwofu

Answer 1

反转您的LOCAL_STATIC_LIBRARIES顺序正常

Answer 2

为了扩展user642960的响应，我将Android.mk中的LOCAL_STATIC_LIBRARIES行更改为：

LOCAL_STATIC_LIBRARIES := pocketsphinx sphinxlm sphinxfeat sphinxfe sphinxutil

这样做之后，提交者描述的错误就消失了。我也升级了NDK，但这似乎并没有解决问题。

ndk-build无法构建PocketSphinxAndroidDemo项目
