I'm unable to add a comment as I am a new user here but I am wondering if there is something not quite right or missing in your environment.

I just created an Ubuntu 18.04 VM to match your o/s and used the Synaptic Package Manager to install openjdk-11-jdk (which installed a couple dependent packages as well). Here are the packages this process installed:

• openjdk-11-jdk • openjdk-11-jdk-headless • openjdk-11-jre • openjdk-11-jre-headless

As thatjeffsmith mentioned the JDK is required (so that SQL Developer can use the JDWP debugging capabilities).

I then unzipped the following SQL Developer package which I had previously downloaded:

• sqldeveloper-19.2.1.247.2212-no-jre.zip

After changing to the correct directory (~/Applications/sqldeveloper/19.2/sqldeveloper in my case) I started SQL Developer as follows:

./sqldeveloper.sh

I then imported my connections from a previous export and was able to connect successfully. I only did a few tests in the Worksheet and browsing objects owned by my user but I didn't encounter any issues using OpenJDK 11.

I had previously encountered issues with OpenJDK 11 and OpenJFX 11 — you can read about that here:

A Tale: SQL Developer 19.2 on Ubuntu 18.04 with OpenJDK 11 and OpenJFX 11

The essence of that thread is that I had "pre-installed" the OpenJFX 11 libraries and that caused a conflict with the OpenJFX 12 libraries that SQL Developer installed automatically.

If you are still trying to pursue this I recommend ensuring you have a the JDK installed and verify as I have done in the following:

You should do this in the code behind:

I think you need axis=0, for sort by column, what is default parameter, so can be omit. Also ascending=True too:

I assume ElkAPI::IManager is in fact an abstract class, the I... stands for "Interface" and these are often abstract.

You are trying to maintain a c++ container class (map) of these. C++ container classes store instances by default. So if you add something to the map it tries to construct an instance and copy or move the content of the source into it. This is not possible as the map element type is abstract - thus error!

Having a map of polymorphic objects is only possible if you use a map of references or pointers to a base type and lifetime-manage the pointed to objects by other means.

You must realize a fundamental difference of c++ to most other languages which is that classes are value-types like structs and thus a variable or member of class type is copied/moved when assigned. If you want to use references only you must use pointers or references and specify so with * or &

The val() method returns or sets the value attribute of the selected elements.

Note: The val() method is mostly used with HTML form elements.

Use

Taking a look at your code (not easy, as I couldn't understand any of the comments..), I think the problem is that you don't initialize adresy[100] to 0 the first you run. So when you use printf() and strcmp(), it depends on the first random \0 it finds. The next words don't have the same issue, since you use memset to set the array to 0's.

Do not use GIT to get it. Just go to GitHub, click on the big green button on the right that says, Clone or download. Then click on Download ZIP.

That will download blackbox_master.zip. Unzip it, then copy all the files in blackbox_master/bin to /usr/bin or /usr/local/bin.
