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

1)before_install:

2)script:

3) after_script:

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

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

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

Hello !

I do not have the code in front of me right now, but I'll try to take a look today.

First, you are right: the path I used is wrong and you used the correct one in your second attempt.

Second, can you tell me which version of java you're using? It seems that you're issue is related tout JavaFX and I don't use it directly. I bet it's an issue comming from OpenCV and you should stick to java 1.8

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).

radium226 commented 5 years ago

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

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

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

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

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!
