android - 无法构建 tess-two 库

Question

我正尝试按照本教程构建 tess-two 库: http://www.codeproject.com/Tips/840623/Android-Character-Recognition在 Windows 上，库的编译在 Linux 上立即失败，我收到以下错误:

make: Entering directory "/home/daniele/tess/eyes-two/src/main"
[armeabi] Compile++ thumb: hydrogen <= clusterer.cpp
[armeabi] Compile++ thumb: hydrogen <= hydrogentextdetector.cpp
[armeabi] Compile++ thumb: hydrogen <= thresholder.cpp
[armeabi] Compile++ thumb: hydrogen <= utilities.cpp
[armeabi] Compile++ thumb: hydrogen <= validator.cpp
[armeabi] Compile++ thumb: hydrogen <= hydrogentextdetector.cpp
[armeabi] Compile++ thumb: hydrogen <= thresholder.cpp
[armeabi] Compile++ thumb: hydrogen <= jni.cpp
make: ***  No rule to make target "jni/../../../../tess-two/libs/armeabi/liblept.so", needed by "obj/local/armeabi/libhydrogen.so".  Stop.
make: Leaving directory "/home/daniele/tess/eyes-two/src/main"

这些是我完成的步骤:

export ANDROID_HOME=/home/daniele/Android/Sdk/
export ANDROID_NDK_HOME=/home/daniele/Android/Ndk
git clone git://github.com/rmtheis/tess-two tess
cd tess
sudo /home/daniele/Android/Ndk/ndk-build -C eyes-two/src/main/

该教程已过时。您可以按照 instructions 跳到该教程中的第 3 步。 (参见“用法”)关于 tess-two 项目。这将使用库的预编译版本，因此您不必自己构建 C++ 代码。
