Hi, I was trying to set up the same environment on my Mac. I got some errors:
Gautam-Mac:tesseract-android-tools Gautam$ ndk-build Install : libjpeg.so => libs/armeabi/libjpeg.so Compile++ thumb : lept <= box.cpp In file included from //Users/Gautam/Documents/workspace/tesseract- android-tools/tesseract-android-tools/jni/ com_googlecode_leptonica_android/box.cpp:17: //Users/Gautam/Documents/workspace/tesseract-android-tools/tesseract- android-tools/jni/com_googlecode_leptonica_android/common.h:22:24: error: allheaders.h: No such file or directory //Users/Gautam/Documents/workspace/tesseract-android-tools/tesseract- android-tools/jni/com_googlecode_leptonica_android/box.cpp: In function 'jint Java_com_googlecode_leptonica_android_Box_nativeCreate(JNIEnv*, _jclass*, jint, jint, jint, jint)': //Users/Gautam/Documents/workspace/tesseract-android-tools/tesseract- android-tools/jni/com_googlecode_leptonica_android/box.cpp:27: error: 'BOX' was not declared in this scope [... many more ...] Any idea why these are being caused?
