Unable to build about tesseract-android-tools HOT 27 CLOSED

Update: I had a nested folder issue from the tar. I'm still getting an error, 
but I think it's related to the double-path in the error (with 
.../obj/lept//cygdrive/c in it. I don't know why it would be generating a path 
with "//" in it, in the middle of "leptonica"

Here's the latest error:

$ ndk-build
Install        : libjpeg.so => libs/armeabi/libjpeg.so
make: *** No rule to make target `//cygdrive/c/android-ndk/tesseract-android-too
ls-1.00/leptonlib-1.66/src/adaptmap.c', needed by `/cygdrive/c/android-ndk/tesse
ract-android-tools-1.00/obj/local/armeabi/objs/lept//cygdrive/c/android-ndk/tess
eract-android-tools-1.00/leptonlib-1.66/src/adaptmap.o'.  Stop.

Hi, I am also getting a similar error. Mine looks like this:

Install        : libjpeg.so => 
/home/tomas/Downloads/tesseract-android-tools-1.00/libs/armeabi
Install        : liblept.so => 
/home/tomas/Downloads/tesseract-android-tools-1.00/libs/armeabi
make: *** No rule to make target 
`//home/tomas/Downloads/tesseract-ocr/ccutil/ocrshell.cpp', needed by 
`/home/tomas/Downloads/tesseract-android-tools-1.00/obj/local/armeabi/objs/tess/
/home/tomas/Downloads/tesseract-ocr/ccutil/ocrshell.o'.  Stop.

I also get the double / in the paths.

Update: I found that this error was occurring because ocrshell.cpp was not a 
file in my tesseract package. This was in fact true for a lot of the files 
described in the tesseract Android.mk file. I have tesseract 3.01 and it is 
very different than tesseract 3.00. I changed the Android.mk file to reflect 
the contents of my tesseract distribution and then ndk-build run successfully.

Thanks for the tip there, I'll keep that in mind. Unfortunately, it's Leptonica 
1.66 that isn't building for me. There is no file list in that Android.mk, just 
a *.c wildcard to find all the source files.

Well, I got some time to set up a VBox image with Ubuntu running. I set up the 
Android SDK and NDK, tested hello-jni.

Following the README, everything builds perfectly. I can now copy the libs 
folder back to Win7, and I think I'm in good shape (Eclipse builds the project).

Now I can start learning... :)

I believe it could be windows related - potentially linked to paths as I didn't 
have success building on Windows Vista either with the same error.

I also went VBox with Ubuntu which worked fine for building it.

I can't build Leptonica either. 

I managed to build it on a Mac but they need me to be able to do so on Windows 
using Cygwin and I'm getting lots of "undefined reference to..." messages.

I temporarily solved the "//" by using the function subst but still I'm unable 
to build it.

Does anyone have any idea? Has anyone been able to successfully build it on 
Windows?

does anyone find a solution for windows ?

i also have this compilo error on cygwin :

$ ndk-build
Install        : libjpeg.so => libs/armeabi/libjpeg.so
make: *** No rule to make target `//cygdrive/c/android-ndk/tesseract-android-too

eract-android-tools-1.00/leptonlib-1.66/src/adaptmap.o'.  Stop.

Ndk-build, I had the same error occurs.
And I have solved this.

'sudo ndk-build'

I do not know why.
If the administrator mode, but you can.

I've tested the Mac.

I have the same error :
Install        : libjpeg.so => libs/armeabi/libjpeg.so

who can share the  generated files such as  lept.so and tess.so,thanks very 
much 

I have the same issue. can anyone tell me how to solve this isseue ?

I am having the same issue. Has anybody got the solution. Please help me.. Its 
urgent..

I had the same problem.
but finally I solved when try again on ubuntu.

Compiling on Ubuntu worked for me as well.

Hi, I did an ugly workaround, changing Android.mk files, I put my answer on 
stackoverflow:

http://stackoverflow.com/q/7334040/614807

If anyone need help, contact-me.

Hi,
I think, I finally figured out why compilation fails:
$(call my-dir) doesn't return an absolute path, but a path relative to your 
current directory. 
You need to edit the files "jni/com_googlecode_leptonica_android/Android.mk" 
and "jni/com_googlecode_tesseract_android/Android.mk". In there change the 
first line from "REAL_LOCAL_PATH := $(call my-dir)" to "REAL_LOCAL_PATH := 
<absolute path to tesseract-android-tools>/$(call my-dir)".

If you set the variables TESSERACT_PATH, LEPTONICA_PATH and LIBJPEG_PATH in 
"jni/Android.mk", then make sure to set them to absolute paths, too (at least 
don't use $(call my-dir) to define them).

Note, that I started the ndk-build from "tesseract-android-tools"'s directory.

My environment: OS: (X)Ubuntu 11.10 and NDK: r7

Hope this helps.

P.S.: If you are using the fork tess-two (uses tesseract 3.01 and leptonica 
1.68) (https://github.com/rmtheis/tess-two) you might need to edit build.xml, 
too. Therefore just insert:

<!-- beginning of modification -->
  <path id="android.libraries.src"><path refid="project.libraries.src" /></path>
  <path id="android.libraries.jars"><path refid="project.libraries.jars" /></path>
<!-- end of modification -->

before "</project>" (see: 
http://rmtheis.wordpress.com/2011/08/06/using-tesseract-tools-for-android-to-cre
ate-a-basic-ocr-app/)

When I call ndk build, it report the error such as
"
D:/jni/test/jni/com_googlecode_leptonica_android/utilities.cpp:102: undefined re
ference to `pixUnsharpMasking'
D:/jni/test/obj/local/armeabi/objs/lept/utilities.o: In function `Java_com_googl

I don't know what can I do for it, can somebody help me?

Thanks，ricardocunha
I solve the problem with the tesseract-android-tools code is revision 6 from 
svn, not the tesseract-android-tools-1.00.tar.gz from Downloads
tesseract-android-tools is revision 6 from svn.

hi all
@ricardocunha
i follow your solution but I get new error can you tell me how fix it

I have exactly the same problem
I use leptonica 1.68 without problem (I make tests with success)
I use tesseract 3.01 without problme (I make tests with success)
So that means that libjepg, zlib and libpng are Ok

But impossible to compile tesseract-android-tools ;-(

Is it possible to get .so ?

Thanks you

On OSX, i followed bjoern's solution and it worked

Can anyone please help me with the issue

@akhila...
it seems that there is problem in mk file.
I tried to build tesseract and able to build.
I mentioned each and every steps on following blog :
http://www.navandroid.blogspot.in/2012/03/how-to-build-and-create-so-file-from.h
tml

I also get the following error when running ndk-build:

Can anyone please help me? Many thanks !

Don't have the resources to support cygwin.
