Dear All,
I started working with Eclipse 16 years ago and I used it for Java and C++ software development in Windows OS.
I also used MinGW, NotePad++ and GNU Octave because they are cross-platform.
Four months ago I installed Ubuntu on my laptop, so I work in two operating systems using the aforementioned software applications. Each time I solved a problem I wrote a 'How to ...' text file in order to keep track of my activity and to have a 'recipe', just in case.
I was working on updating the C++ applications in order to be also used in Ubuntu, to develop cross-platform software. The large number of header files is useful to quickly develop computer assisted hybrid models (engineering, economics and others), i.e. dedicated solvers, scientific visualization applications and data interfaces.
Yesterday Eclipse (Ubuntu) suddenly reported that it cannot handle C++ files and asked me to select and outer editor for the source files. The error was persistent, therefore I decided to re-install Eclipse.
I removed everything and I installed Eclipse from the Ubuntu Developer Tools, as I did before.
The results was a disaster! The error is:
!SESSION Tue Apr 30 15:07:45 EEST 2019 -----------------------------------------
!ENTRY org.eclipse.equinox.launcher 4 0 2019-04-30 15:07:45.733

Several similar errors were reported, without any solution, so far:

https://askubuntu.com/questions/1031171/eclipse-doesnt-start-on-ubuntu-18-04
I removed and re-install Eclipse several times using various methods but the error is the same.
I still want to use Eclipse in my projects, because I consider it is a reliable IDE. However, now I am under presser to complete a project and I don't like to search for alternatives to Eclipse.
Any idea is welcome!
Thank you,
Emil
