构建 tesseract Android 工具时出错

Question

我正在尝试为 android 构建 Tesseract，但遇到了一些问题。我正在关注tutorial，其中给出了构建 Tesseract 的以下说明。

cd <project-directory>
curl -O https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.02.tar.gz
curl -O http://leptonica.googlecode.com/files/leptonica-1.69.tar.gz
tar -zxvf tesseract-ocr-3.02.02.tar.gz
tar -zxvf leptonica-1.69.tar.gz
rm -f tesseract-ocr-3.02.02.tar.gz
rm -f leptonica-1.69.tar.gz
mv tesseract-3.02.02 jni/com_googlecode_tesseract_android/src
mv leptonica-1.69 jni/com_googlecode_leptonica_android/src
ndk-build -j8
android update project --target 1 --path .
ant debug (release)

首先没有路径（即没有src目录）

jni/com_googlecode_tesseract_android/src
jni/com_googlecode_leptonica_android/src

所以我不太确定他们应该去哪里，所以我把它们留在了提取的文件夹中。 还有运行时

ndk-build -j8 

我收到以下错误

更新：

重新开始后有趣

mv tesseract-ocr jni/com_googlecode_tesseract_android/src
mv leptonica-1.69 jni/com_googlecode_leptonica_android/src

正在工作。

在构建过程中出现以下错误：

我也遇到了同样的问题。 这些是我遵循的步骤：

• 从 github.com/alanv/tesseract-android-tools 下载了 tesseract_android_tools 项目
• 提取并通过终端移动到 tesseract-android-tools
• 卷曲 -O https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.02.tar.gz
• 卷曲-O http://leptonica.googlecode.com/files/leptonica-1.69.tar.gz
• tar -zxvf tesseract-ocr-3.02.02.tar.gz
• tar -zxvf leptonica-1.69.tar.gz
• rm -f tesseract-ocr-3.02.02.tar.gz
• rm -f leptonica-1.69.tar.gz
• mv tesseract-3.02.02 jni/com_googlecode_tesseract_android/src
• mv leptonica-1.69 jni/com_googlecode_leptonica_android/src
• 我尝试运行android-ndk-r9，但它一直抛出错误jni/com_googlecode_tesseract_android/src/dict/permdawg.cpp:208:62: error: format not a string literal and no format arguments [-Werror=format-security] cc1plus.exe: some warnings being treated as errors
• 我将 jni/com_googlecode_tesseract_android/src/dict/permdawg.cpp 第 208 行从 fprintf(output_ambig_words_file_, word_str.string()); 修改为 fprintf(output_ambig_words_file_, "%s", word_str.string());
• 我尝试运行android.bat update project -p .，但一直抱怨Error: The project either has no target set or the target is invalid. Please provide a --target to the 'android.bat update' command.
• 我提供了目标，首先运行 android list targets 以获取我拥有的目标，然后运行 ​​android update project -t 7 -p .，因为 7 是我的首选目标
• 成功了。
• 抱歉回复晚了
