尝试在带有Cygwin的Windows上使用NDK为Android构建PocketSphinx时出现的问题

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。项目的/jni/文件夹中的Android.mk文件如下所示-

# 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)

运行ndk build命令时，出现以下错误：

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

我可以建立所有的ndk样本刚刚好。有什么线索导致这个错误吗？非常感谢

你知道这个项目以前是否成功地使用cygwin构建？Cygwin有许多奇怪之处，从windows驱动器号与unix路径的笨拙组合，到异常地解释汇编路径中无意中出现的双斜杠，等等。您可以尝试使用/cygdrive/e/类型的路径而不是驱动器号，但谁知道这是否有用。

Jason， 您必须将sphinx路径更改为cygwin格式，即不带“：”
改变

这将修复错误

Jason，编辑jni/Android.mk文件

换行162：

LOCAL_STATIC_LIBRARIES := sphinxutil sphinxfe sphinxfeat sphinxlm pocketsphinx

致：

这将解决您的问题。

我使用以下链接在Windows上的Android上构建Pocketsphinx

但它遗漏了@Hitesh提到的在jni/Android.mk文件中替换本地静态库的一步，我能够构建到最新的0.8版本。。谢谢@Hitesh

@Chris-你能把这个作为回答吗？你提到了驱动器号和路径，这让我得到了正确的答案。我希望能够将您的答案标记为正确答案：）我在SPHINX_路径声明下添加了SPHINX_路径：=$（shell cygpath-u$（SPHINX_路径）），现在一切都很好！谢谢这个答案把我带到了正确的地方。我在SPHINX_路径声明下添加了SPHINX_路径：=$（shell cygpath-u$（SPHINX_路径）），现在一切都很好！谢谢
