Errors building tesseract Android tools

Errors building tesseract Android tools - android

I am trying to build Tesseract for android and have been getting issues. I am following a tutorial where the following instructions have been given to build Tesseract.
cd <project-directory>
curl -O https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.02.tar.gz
curl -O http://leptonica.googlecode.com/files/leptonica-1.69.tar.gz
tar -zxvf tesseract-ocr-3.02.02.tar.gz
tar -zxvf leptonica-1.69.tar.gz
rm -f tesseract-ocr-3.02.02.tar.gz
rm -f leptonica-1.69.tar.gz
mv tesseract-3.02.02 jni/com_googlecode_tesseract_android/src
mv leptonica-1.69 jni/com_googlecode_leptonica_android/src
ndk-build -j8
android update project --target 1 --path .
ant debug (release)
Firstly there is no path at (i.e no src directory)
jni/com_googlecode_tesseract_android/src
jni/com_googlecode_leptonica_android/src
So I am not too sure where they should go, so I left them in their extracted folder.
Also when running
ndk-build -j8
I get the following errors

UPDATE:
Interestingly after starting again
mv tesseract-ocr jni/com_googlecode_tesseract_android/src
mv leptonica-1.69 jni/com_googlecode_leptonica_android/src
are working.
During building I get the following errors:
jni/com_googlecode_tesseract_android/src/dict/permdawg.cpp: In member function 'void tesseract::Dict::go_deeper_dawg_fxn(const char*, const BLOB_CHOICE_LIST_VECTOR&, int, const CHAR_FRAGMENT_INFO*, bool, WERD_CHOICE*, float*, float*, WERD_CHOICE*, int*, void*)':

^
cc1plus: some warnings being treated as errors
make: *** [obj/local/armeabi/objs/tess/src/dict/permdawg.o] Error 1
make: *** Waiting for unfinished jobs....

I also had the same problem.
These are the steps I followed:
Downloaded the tesseract_android_tools project from github.com/alanv/tesseract-android-tools
Extracted it and moved to tesseract-android-tools via Terminal
curl -O https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.02.tar.gz
curl -O http://leptonica.googlecode.com/files/leptonica-1.69.tar.gz
tar -zxvf tesseract-ocr-3.02.02.tar.gz
tar -zxvf leptonica-1.69.tar.gz
rm -f tesseract-ocr-3.02.02.tar.gz
rm -f leptonica-1.69.tar.gz
mv tesseract-3.02.02 jni/com_googlecode_tesseract_android/src
mv leptonica-1.69 jni/com_googlecode_leptonica_android/src
I tried running android-ndk-r9 but it kept on throwing the error jni/com_googlecode_tesseract_android/src/dict/permdawg.cpp:208:62: error: format not a string literal and no format arguments [-Werror=format-security]
cc1plus.exe: some warnings being treated as errors
I modified jni/com_googlecode_tesseract_android/src/dict/permdawg.cpp line 208 from fprintf(output_ambig_words_file_, word_str.string()); to fprintf(output_ambig_words_file_, "%s", word_str.string());
I tried running android.bat update project -p . but kept on complaining that Error: The project either has no target set or the target is invalid.
Please provide a --target to the 'android.bat update' command.
I provided the target by first running android list targets to get the targets I have and then android update project -t 7 -p . since 7 was my preferred target
That worked.
Sorry for the late reply

ubuntu 15.10 64bit build Android source 5.0 version

How can I fix this problem？When I was building the Android source of 5.0 with
'make -j4', it was causing a problem.
This is the error log:

In my case, I get similar error when build Marshmallow 6.0.1_r1 in Ubuntu 18.04.
If you get similar errors like this:
build/core/binary.mk:646: recipe for target 'out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_l.cpp' failed
make: *** [out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_l.cpp] Aborted (core dumped)
Look at the line carefully, it's a core dumped, so I use coredumpctl list, navigate to the end of list with G, then figure out the core dump executed path (right column) is prebuilts/misc/linux-x86/flex/flex-2.5.39
And the PREBUILT file shows:
xb#dnxb:~/my_android_src/prebuilts/misc/linux-x86/flex$ cat PREBUILT
The objects in this prebuilt directory can be rebuilt
using the source archive hosted at
http://sourceforge.net/projects/flex/files/
Commands:
./configure
make CFLAGS="-static" LDFLAGS="-static"
# (Disregard the errors at the end of the build)
rm flex
make CFLAGS="-static" LDFLAGS="-static" flex
# Copy the linker command line, replace it with static libm.a
gcc -static -static -o flex ccl.o dfa.o ecs.o scanflags.o gen.o main.o misc.o nfa.o parse.o scan.o skel.o sym.o tblcmp.o yylex.o options.o scanopt.o buf.o tables.o tables_shared.o filter.o regex.o /usr/lib/x86_64-linux-gnu/libm.a
xb#dnxb:~/my_android_src/prebuilts/misc/linux-x86/flex$
That's it, the first 2 lines said that you probably need to rebuild yourself if something went wrong since this flex-2.5.39 binary is prebuilt in another platform.
So simply untar the flex-2.5.39.tar.gz of this directory, go to the extracted flex-2.5.39 directory, then follows the PREBUILT instruction above.
In short, you need to do the following steps:
cd <ANDROID_TREE_DIR>/prebuilts/misc/linux-x86/flex
tar -zxvf flex-2.5.39.tar.gz
cd flex-2.5.39
make CFLAGS="-static" LDFLAGS="-static"
rm flex
make CFLAGS="-static" LDFLAGS="-static" flex
/bin/bash ./libtool --tag=CC --mode=link gcc -static -static -o flex ccl.o dfa.o ecs.o scanflags.o gen.o main.o misc.o nfa.o parse.o scan.o skel.o sym.o tblcmp.o yylex.o options.o scanopt.o buf.o tables.o tables_shared.o filter.o regex.o lib/libcompat.la /usr/lib/x86_64-linux-gnu/libm.a
cd ..
cp flex-2.5.39/flex .
mv flex flex-2.5.39
ls -la

NOTICE

Now try to do make <module> -j4 again, no longer abort on such error.
p/s: Alternative way will be LANG=C make pm -j4 if you see something like LC_* error message.
p/s2: I also need symlink ld as below to fixed 'out/host/linux-x86/obj/lib/libart.so' failed and error: unsupported reloc 42:

How to compile and execute MPICH2 for Android

For cross compiling MPICH2 for Android.
I found the reference here
http://hex.ro/wp/projects/personal-cloud-computing/compiling-mpich2-for-android-and-running-on-two-phones/
and here
www.scientificbulletin.upb.ro/rev_docs_arhiva/fullffc_583765.
I did following
BuildRoot
Used Build Root (buildroot-2016.02) for cross compiling ARM toolchain
Target options :
Target Architecture as ARM little endian
Target binary format as ELF
Selected Toolchain as Buildroot toolchain (Internal)
Kernel headers as 3.12.x
C library as uClibc
After this make command was run.
MPICH2
mpich-3.2.tar.gz was extracted and following commands were executed
1. $ export PATH=/home/mpiuser/CrossBuild/buildroot-2016.02/output/host/usr/bin:$PATH
2. $ sudo ./configure --prefix=/home/mpiuser/CrossBuild/arm-mpich-install --disable-fortran CC=/home/mpiuser/CrossBuild/buildroot-2016.02/output/host/usr/bin/arm-linux-gcc --host=arm-linux
After this make was run for mpich-3.2, and during compilation following error was thrown :
GEN lib/libmpi.la
CXX src/binding/cxx/initcxx.lo
CXXLD lib/libmpicxx.la
lib/.libs/libmpi.so: error adding symbols: File in wrong format
collect2: error: ld returned 1 exit status

Request to please help. Thanks

Error: file not found: arch/arm/boot/compressed/piggy.lzo

I am trying to build android project
Getting below error even after setting correct path for toolchains

Compiling muPDF lib in Eclipse "cannot unlink `NUL': Invalid argument Android NDK" Error

I'm trying to compile the muPDF lib in Eclipse on Windows 7. I'm following these steps.
On this step
Build the native code libraries:

How to prevent cmake adding "compatibility_version" for gcc?

I'm pretty new to cmake and i'm trying to cross-compile libftdi for ARM Linux (Android).
Why cmake adds "-compatibility_version" to gcc command-line which leads to error:
/softdev/arm-toolchain/bin/arm-linux-androideabi-gcc -O2 -g -DNDEBUG -dynamiclib -Wl,-headerpad_max_install_names -L/softdev/arm-libs/lib -compatibility_version 2.0.0 -current_version 2.0.0 -o libftdi1.2.0.0.dylib -install_name /Users/asmirnov/Documents/dev/src/libftdi-1.0/src/libftdi1.2.dylib CMakeFiles/ftdi1.dir/ftdi.c.o CMakeFiles/ftdi1.dir/ftdi_stream.c.o /usr/local/lib/libusb-1.0.dylib
arm-linux-androideabi-gcc: error: 2.0.0: No such file or directory
arm-linux-androideabi-gcc: error: 2.0.0: No such file or directory
arm-linux-androideabi-gcc: error: /Users/asmirnov/Documents/dev/src/libftdi-1.0/src/libftdi1.2.dylib: No such file or directory
arm-linux-androideabi-gcc: error: unrecognized option '-compatibility_version'
arm-linux-androideabi-gcc: error: unrecognized option '-current_version'
make[2]: *** [src/libftdi1.2.0.0.dylib] Error 1
make[1]: *** [src/CMakeFiles/ftdi1.dir/all] Error 2
make: *** [all] Error 2
Since i can't find "compatibility_version" command-line parameter in supported by gcc parameters list is it cmake error or cmake configuration problem?
UPDATE: problem #1 solved (hacked)
i've solved the problem by commenting the next lines in ../Modules/Platforms/Darwin.cmake:
# 4ntoine (fix for libftdi compilation using cmake)
#set(CMAKE_C_OSX_COMPATIBILITY_VERSION_FLAG "-compatibility_version ")
#set(CMAKE_C_OSX_CURRENT_VERSION_FLAG "-current_version ")
#set(CMAKE_CXX_OSX_COMPATIBILITY_VERSION_FLAG "${CMAKE_C_OSX_COMPATIBILITY_VERSION_FLAG}")
#set(CMAKE_CXX_OSX_CURRENT_VERSION_FLAG "${CMAKE_C_OSX_CURRENT_VERSION_FLAG}")
# ...
# 4ntoine (fix for libftdi build using cmake)
#if(NOT XCODE)
# Enable shared library versioning. This flag is not actually referenced
# but the fact that the setting exists will cause the generators to support
# soname computation.
# set(CMAKE_SHARED_LIBRARY_SONAME_C_FLAG "-install_name")
#endif()
I know it's not good especially when you are not sure what you're doing ;)
Now i have another problem #2:
cd /Users/asmirnov/Documents/dev/src/libftdi-1.0/build/src && /usr/local/Cellar/cmake/2.8.11.1/bin/cmake -E cmake_link_script CMakeFiles/ftdi1.dir/link.txt --verbose=1
