Belajar Bareng Pengembangan Software: Open Data Kit : ODK Scan

Status : Draft

Build

Ketika melakukan kompilasi ODKScanCore, Anda harus menggunakan OpenCV 2.3.1, download disini : https://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.3.1/ (harus melakukan proses kompilasi dari source), ketika melakukan kompilasi, nonaktifkan opsi ffmpeg :

Untuk Mac OS X, penulis menggunakan Mojave, maka sebelumnya perlu menginstall OpenCV 2 dengan perintah :

brew install opencv@2

lalu edit src/Aligner.cpp dan tambahkan baris berikut :

#include <opencv2/nonfree/features2d.hpp>

Lalu untuk Makefile ubah bagian berikut :

INCLUDES := $(OPENCV_INCLUDES)\
-I./jsoncpp-src-0.5.0/include\
-I./src -I./\
-L/usr/lib
-I./zxing/core/src -I./zxing/cli/src

menjadi :

INCLUDES := -I/usr/local/Cellar/opencv\@2/2.4.13.7_3/include/\

-L/usr/local/Cellar/opencv\@2/2.4.13.7_3/lib\

-lopencv_core\

-lopencv_imgproc\

-lopencv_highgui\

-lopencv_ml\

-lopencv_video\

-lopencv_features2d\

-lopencv_calib3d\

-lopencv_objdetect\

-lopencv_contrib\

-lopencv_legacy\

-lopencv_flann\

-lopencv_nonfree\

-liconv\

-I./jsoncpp-src-0.5.0/include\

-I./src -I./\

-lboost_filesystem -lboost_system\

-I./zxing/core/src -I./zxing/cli/src

Berikutnya berlaku untuk Linux dan Mac

cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON \
-D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON \
-D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=OFF \
-D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_VTK=ON \
-D WITH_FFMPEG=OFF ..

Error 1 :

OpenCV-2.3.1/share/OpenCV/../../include/opencv2/flann/any.h:88:67: error: call to function 'operator<<' that is neither visible in the template
definition nor found by argument-dependent lookup

Solusi, terapkan patch berikut [sumber]:

/home/wildan/Android/Sdk/ndk-bundle/sources/cxx-stl/gnu-libstdc++/4.9/include/ext/atomicity.h:49: error: undefined reference to '__atomic_fetch_add_4

Solusi :

Edit :

bubblebot_lib/jni/Android.mk

Tambahkan -latomic di LOCAL_LDLIBS :

LOCAL_LDLIBS += $(OPENCV_LIBS) $(ANDROID_OPENCV_LIBS) -llog -ldl -lGLESv2 -latomic

OSX Mojave

cd OpenCV-2.3.1
mkdir build
cd build
cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=OFF -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_VTK=ON -D WITH_FFMPEG=OFF ..

Perbaikan, ubah :

if( rows < 0 || cols < 0 || dt < 0 ) menjadi : if( rows < 0 || cols < 0 || dt != nullptr )

dan

if( vtx_dt > 0 ) nenjadi if( vtx_dt != nullptr )

Error 4

Solusi :

tambahkan :

#include <unistd.h>

di OpenCV-2.3.1/modules/highgui/src/window_QT.cpp

Error 5

Solusi :

Here is a workaround solution to fix the issue:

Download MACOSX SDK https://codeload.github.com/phracker/MacOSX-SDKs/zip/MacOSX10.11.sdk
extract head files from MacOSX10.11.sdk/MacOSX10.11.sdk/System/Library/Frameworks/QTKit.framework/Headers/
Create a folder under opencv source file folder: opencv-2.3.1/modules/highgui/src/QTKit, and copy all header files into the folder.

Solusi : untuk masalah ini bisa dibaca di : Error migrating from GCC to Clang - undefined reference to atomic #104.

yaitu di : bubblebot_lib/jni/Android.mk

LOCAL_LDLIBS += $(OPENCV_LIBS) $(ANDROID_OPENCV_LIBS) -llog -ldl -lGLESv2

ditambah -latomic menjadi :

LOCAL_LDLIBS += $(OPENCV_LIBS) $(ANDROID_OPENCV_LIBS) -llog -ldl -lGLESv2 -latomic

ubah

menjadi
