The android.git.kernel.org is down. How can we build the tesseract 3.0? about tesseract-android-tools HOT 11 CLOSED

Temporarily I use

http://code.google.com/p/androido3d/source/browse/android/apps/o3d/project/jni/t
hird_party/libjpeg/?r=6bc15cab44a5f9c13b193bc7397b6ad5eef8397c

code and the Android.mk

you can use the mirror 

https://github.com/android/platform_external_jpeg

The code and Android.mk from mirror 
site:https://github.com/android/platform_external_jpeg cannot work.

I got the error message from the ndk-build as below:

"C:/OCR/tesseract-android-tools-1.00/external/libjpeg/jmem-ashmem.c:22:27: 
error:
 cutils/ashmem.h: No such file or directory
make: *** [/cygdrive/c/OCR/tesseract-android-tools-1.00/obj/local/armeabi/objs/j
peg/jmem-ashmem.o] Error 1 "

It seems looking for the "cutils/ashmem.h" file, but this file is not included 
in the  files downloaded from mirror site.

Anyone know how to solve this problem?

# libjpeg/Android.mk for tessaract build change 
# comment use of jmem-ashmem.c  
# uncomment use of jmem-android.c

# use ashmem as libjpeg decoder's backing store
#LOCAL_CFLAGS += -DUSE_ANDROID_ASHMEM
#LOCAL_SRC_FILES += \
#   jmem-ashmem.c

# the original android memory manager.
# use sdcard as libjpeg decoder's backing store
LOCAL_SRC_FILES += \
    jmem-android.c

but now I got another problem:
"Compile arm    : jpeg <= jmem-android.c
SharedLibrary  : libjpeg.so
Install        : libjpeg.so => libs/armeabi/libjpeg.so
make: *** No rule to make target `//cygdrive/c/OCR/tesseract-android-tools-1.00/

ools-1.00/external/leptonlib-1.66/src/adaptmap.o'.  Stop."

I run cygwin on my windows 7, it seems the path problem with "//".....don't 
know how to fix it yet.

Any ideas?

copy the files in jni/com_googlecode_leptonica_android external/  to 
external/leptonlib-1.66 folder, inside leptonlib-1.66 run ./configure, wait for 
it and type make, this will take some time.

rafaell,
I have the same problem as ChunHsia, and tried your fix, with the same results. 
I copied the files and ran .configure and make; here's the output from the 
*second* time I tried it:

See my answer on issue 4, using windows with cygwin or mac, ndk has a little 
problem to compile, try to use a linux distribuition, or change Android.mk 
files for windows or mac, I can send my modified mk files if you need.

Yes, alright, it feels like I'm giving in, but indeed, I used my OpenSuSE 11.3 
virtual machine and the Tesseract tools compiled with no problem! Since I'm not 
going to be doing any mods to Tesseract (I hope!) I guess that's an OK solution 
for me - I won't have to go back and forth between systems too often (since I 
still can't get 'shared folders' for work for me under VMWare Player I have to 
move files with a USB stick!).

Thanks!

Hi,

I tried using the version from the github mirror (
https://github.com/android/platform_external_jpeg) and it is failing to compile 
for me.

I did go ahead and change the Android.mk file to use jmem-android.c.

Here is what the log says as it is failing and a little before:

Does anyone have any idea what the issue is? Months ago I tried compiling when 
android.git.kernel.org was not down and everything went well for me then. I 
tried a clean install now which is appearing to have been a mistake. :) By the 
way I am compiling on an Ubuntu VM. 

Removed libjpeg.
