Hi,
I am trying to build alanv's tesseract port for android using android NDK. I am just helpless there as I tried again and again to build the tesseract but unable to accomplish it and always got linking errors of libleptonica. Note that i do have shared library of libleptonica and i do put liptonica source under <ndk-root>/sources/tesseract/leptonica. I put my tesseract sources under <ndk-root>/sources/tesseract. My application.mk looks like this

Code: Select all

APP_PROJECT_PATH  := /cygdrive/e/Mobile_Development_Stuff/android-ndk-r5/sources/tesseract
APP_BUILD_SCRIPT  := $(APP_PROJECT_PATH)/Android.mk
APP_MODULES      := libocr


and my android.mk looks like this.

Code: Select all

ifneq ($(TARGET_SIMULATOR),true)
