android - 尝试使用 Cygwin 在 Windows 上使用 NDK 为 Android 构建 PocketSphinx 的问题

Question

我目前正在尝试使用 Windows 上的 NDK 和 Cygwin 为 Android 构建 PocketSphinx 库。我有 PocketSphinxAndroidDemo 项目代码。我还将 pocketsphinx 和 shpinxbase 项目作为 E:/Development/CMUSphinx 文件夹的子文件夹。

我正在尝试使用项目文件夹中的 ndk-build 进行构建。项目/jni/文件夹下的Android.mk文件是这样的-

# Build the native component of the PocketSphinx library for Android.

# You MUST change this to the absolute path of the directory containing
# sphinxbase and pocketsphinx source code.
SPHINX_PATH := E:/Development/CMUSphinx

# Copy this Android.mk along with pocketsphinx_wrap.c and the contents of the 'edu' folder
# built by swig to the jni/ directory of your Android project.
BASE_PATH := $(call my-dir)

当我运行 ndk-build 命令时，出现以下错误:

build-binary.mk:197: *** target pattern contains no '%'. Stop.

我可以很好地构建所有 ndk 样本。任何线索是什么导致了这个错误？非常感谢!

Jason，编辑 jni/Android.mk 文件

更改第 162 行:

LOCAL_STATIC_LIBRARIES := sphinxutil sphinxfe sphinxfeat sphinxlm pocketsphinx

到:

LOCAL_STATIC_LIBRARIES := pocketsphinx sphinxlm sphinxfeat sphinxfe sphinxutil

这将解决您的问题。
