Question

我正在尝试为Android构建Tesseract并且一直在遇到问题。我正在关注tutorial，其中已经给出了以下说明来构建Tesseract。

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他们提取的文件夹中。还在运行时

ndk-build -j8

我收到以下错误

更新：

有趣的是在重新开始之后

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

正在运作。

在构建过程中，我收到以下错误：

jni/com_googlecode_tesseract_android/src/dict/permdawg.cpp: In member function 'void tesseract::Dict::go_deeper_dawg_fxn(const char*, const BLOB_CHOICE_LIST_VECTOR&, int, const CHAR_FRAGMENT_INFO*, bool, WERD_CHOICE*, float*, float*, WERD_CHOICE*, int*, void*)':

我也有同样的问题。这些是我遵循的步骤：

从github.com/alanv/tesseract-android-tools
提取它并通过终端
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
我尝试了android-ndk-r9，但它继续抛出错误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());
我尝试了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android update project -t 7 -p .，因为7是我的首选目标
那很有用。
对不起，迟到的回复
