Summary:
I am using 'com.rmtheis:tess-two:8.0.0' and compiled for below architectures

ndk {
abiFilters "armeabi-v7a", "arm64-v8a"
}
it works for "armeabi-v7a" only.

Steps to reproduce the issue:

1. create a new android app using tess-two.
2. add following architecture.
   ndk {
   abiFilters "armeabi-v7a", "arm64-v8a"
   }
3. Then from android app call
   TessBaseAPI baseApi = new TessBaseAPI();

Expected result:

it should execute the TessBaseAPI without any issues.

Actual result:

Hi,

Do we need to make changes as mentioned in commit #124 to libjpeg ?

libpng has added support for "arm64-v8a" and not libjpeg, because we searched "ARM_NEON" in repository and only found in (https://github.com/rmtheis/tess-two/search?utf8=%E2%9C%93&q=__ARM_NEON__&type=) in below files.

tess-two/jni/libpng/pngpriv.h
tess-two/jni/libpng/configure.ac
tess-two/jni/libpng/scripts/pnglibconf.dfa
tess-two/jni/libpng/CHANGES

Thanks.

Hi,

Sorry for closing without providing details.

We resolved the issue by using below version of tess-two.
compile 'com.rmtheis:tess-two:7.0.0'

We also added below code before calling the api as below.

 System.loadLibrary("jpgt");

                        TessBaseAPI baseApi = new TessBaseAPI();
                        baseApi.setDebug(true);
                        baseApi.init(DATA_PATH, lang1);

We will not close this issue since it is still persists in 8.0.0

Thanks.

[rmtheis]

Thanks for contributing this.

I wasn't able to reproduce this issue when running the unit tests on 64-bit emulator. Do the unit tests pass for you?

[rmtheis]

I tried reproducing this on a 64-bit device and a 64-bit emulator. I wasn't able to reproduce the issue. Please reopen if you're able to provide more info.

[juechenshiai]

I have the same problem with 8.0.0

[rmtheis]

Possibly related to #150.

[sarendshorst]

@rmtheis With 7.0.0 I get the following libs:

With 8.0.0:

What should I do to get the missing libs on 8.0.0?

[rmtheis]

@NFear That's working as intended. Use 7.0.0 or follow the instructions in BUILDING.md to do the build step manually

[JcMinarro]

I am getting the same problem with version 8.0.0, How could I use version 8.0.0 on 64-bit devices?
