I am facing a problem while trying to link opencv to CPP project generated by Matlab Coder. In the auto generated Makefile of the project, I added pkg-config --cflags opencv to CFLAGS and pkg-config --libs opencv to LIBS (opencv 3.4), which then gives the error "No rule to make target '-L/usr/local/lib'". Any ideas how to fix ther error?

Here is a unit testing class for a java spring data repository layer. I have a spring data repository layer in which the annotation @Autowired is used to inject TestEntityManager type object (belongs to spring data package). The autowiring works whitout adding @RunWith(SpringRunner.class) annotation ! So what is the problem ? Well, I think that injection should not be possible whitout adding @RunWith(SpringRunner.class) annotation to the class : it should not work without it theorically. How is it possible ? Does someone have any answer ?

Here is my strange bloc of code that amazingly that works :

package org.loiz.demo;

I have a test class that contains two method tests. These test methods are executed with a certain order using @Order annotaion which works well. The first method inserts a known value in h2 that will have id = 21 (trust me indeed, on startup 20 values are created by me when spring starts up, in the spring application configuration class annotated @SpringBootApplication), here is the inserted value in test layer :

User userStub = new User("prenom21", "Nom21"))

• The second method has to read the inserted value but i get a null object. Maybe i did something wrong, but i would like to know what.

• The script is available here for viewing or download (you can run it to see the error) : https://github.com/userInterview/LoizSpringRestPersistenceTests/blob/main/src/test/java/org/loiz/demo/LoizPersistenceTest.java

• Below, At code line written in bold case (line 65), i should have an object in UserRead object created by the first test method but i have null object. Is this normal ?

I am generating model in JavaScript with -Dmodels option. The generated code contains require module loader used in Node, but I am using Vue Js. So, I have problem when I require these files in Vue Js project. It gives me an error about superagent - it suppose I will use superagent which is also autogenerated. What I want is to generate pure models with ES6 export/import statements. Is it possible with Swagger Codegen or should I use something else? Currently, I am using openapi-client but there is no support for model generation.

I have several controllers within my project which have multiple Get methods:
