myproject

I am following the compilation process of this project, in the last step on 3

1)before_install:

  • ./dlib-java make-opencv
  • ./dlib-java make-dlib

2)script:

  • ./dlib-java mvn-package
  1. after_script:
  • ./dlib-java java-jar

I'm throwing an error in this step that I detail below

./dlib-java java-jar

//LD_LIBRARY_PATH="/tmp/dlib/usr/lib;/tmp/opencv/usr/lib;/tmp/opencv/usr/share/OpenCV/java" java -jar "target/dlib-1.0-SNAPSHOT.jar"

Error: Unable to access jarfile target/dlib-1.0-SNAPSHOT.jar

also try to change that line in the script code dlib-java

LD_LIBRARY_PATH="/tmp/dlib/usr/lib;/tmp/opencv/usr/lib;/tmp/opencv/usr/share/OpenCV/java" java -jar "dlib/target/dlib-1.0-SNAPSHOT.jar"

but I deployed the following error
./dlib-java java-jar
Error: no se ha encontrado el método principal en la clase com.github.radium226.dlib.DLib, defina el método principal del siguiente modo:\n public static void main(String[] args)\nde lo contrario, se deberá ampliar una clase de aplicación JavaFX javafx.application.Application

What is I doing wrong, the classes are downloaded from the project and followed step by step the same, could you help me? thank you
I detail my output in the command construction / dlib-java mvn-package

./dlib-java mvn-package

Other considerations that I had to modify for me to compile are

/home/usuario/dlib_java/dlib-java-master/dlib/src/main/native/make.sh

I had to modify the function by adding -std = c ++ 11

gcc :: compile_object ()
{
declare source_file_path = "$ {1}"
declare target_file_path = "$ {2}"

g ++ \
    -fPIC \
    -fno-strict-aliasing \
    -I "/ usr / lib / jvm / java-8-openjdk-amd64 / include" \
    -I "/ usr / lib / jvm / java-8-openjdk-amd64 / include / linux" \
    $ (pkg-config --cflags "dlib-1") \
    $ (pkg-config --cflags "opencv") \
    -I "$ {SOURCE_FOLDER}" \
    -I "$ {SOURCE_FOLDER} / include" \
    -c "$ {source_file_path}" -o "$ {target_file_path}" -std = c ++ 11

}
and in the

/home/usuario/dlib_java/dlib-java-master/dlib/src/main/native/face_descriptor_computer.hpp

Comment this line

//crops.push_back(dlib::jitter_image(img,rnd));

and the line

cv :: Mat m; // = dlib :: toMat (face_chip);

thanks for your time.
regards

Agustín

Hi! Thanks a lot for you feedback.

I've cloned the source and took a look of everything and I figured out that a lot of stuff were actually missing. I'l try to update the dlib-java script next week in order to make everything work. I'm also going to add some of the snippets you mentioned above (like the -std=c++ stuff).

Hi! I've made multiple updates in the master branch. I hope it fixes the issues you encountered. I upgraded OpenCV and DLib and also fixed a lot of stuff which were wrong in dlib-java. It's a first step to make this all thing more robust.

Feel free to make me some feedback!

Hello how are you? thank you very much for the changes and for your work!

Download the project again and now compile everything without problems to a certain extent, which I detail below, I think it is my mistake in my linux but I do not realize how to fix it

Any suggestions? , I will continue trying to solve this error.

thank you very much, greetings

I found the error in the opencv4.pc file, modify the path that is in bold

I finally run the last command and I have a link error with the opencv jar apparently

usuario@usuario-VirtualBox:~/dlib_java/dlib-java-master$ ./dlib-java "java-jar"
Exception in thread "main" java.lang.UnsatisfiedLinkError: opencv_java401

Fix this problem by modifying this code, is this correct?

dlib_java::exec_jar()
{
LD_LIBRARY_PATH="/tmp/opencv/usr/lib:/tmp/opencv/usr/share/java/opencv4:/tmp/dlib/usr/lib" java -jar "dlib/target/dlib-1.0-SNAPSHOT.jar"
"$( find . -name "lena.jpg" -print | head -n1 )"
}

Now what does not load me correctly is the libdlib-java.so

usuario@usuario-VirtualBox:~/dlib_java/dlib-java-master$ ./dlib-java "java-jar"
Loading libraryName ..dlib-java
InputStream inputStream = Libraries.class.getClassLoader().getResourceAsStream(libraryFileName(libraryName));dlib-java

Files.copy(inputStream, libraryFilePath);dlib-java

I'm looking for my error in the Libraries.java code

public static LibraryLoader SWIG_GENERATED_RESOURCES = libraryName -> {
Path libraryFilePath = Paths
.get(System.getProperty("user.dir"))
.resolve("target/generated-resources/swig/")
.resolve(libraryFileName(libraryName));

    if (Files.exists(libraryFilePath)) {
        System.load(libraryFilePath.toString());
    } else {
        throw new UnsatisfiedLinkError(libraryName);
    }
};

I was making some changes in the code, to be able to load the file libdib-java.so
dlibjava

usuario@usuario-VirtualBox:~/dlib_java/dlib-java-master$ ./dlib-java "java-jar"
libraryFilePath :/usr/share/dlibjava/libdlib-java.so

I took some time... But I rewrote the compilation process. If you're still interested, you can check the README.md and see the new Makefiles!
