Codeblocks Crash

  • 772

I don't have a good experience with codeblocks on Ubuntu. I've tried in 15.10 and 16.04 and it always crashes after a while. I just open a console application, create some .h files and run. I use it for a c++ university class. I don't do complex stuff. I reinstalled many times on both 15.10 and 16.04 and it keeps crashing .

    You can use Geany to write, edit, compile and run C++ source code. But if you want to use codeblocks, then please install the latest version of codeblocks 16.01. To install codeblocks 16.01 run this commands in terminal.

    sudo apt-add-repository ppa:damien-moore/codeblocks-stable
sudo apt-get update
sudo apt-get install codeblocks

  2. Try to disable symbol browser of code completion and see if the crushes stop.

    Go to:

    • Settings
    • Editor
    • Code Completion (on the left)
    • Symbols browser

    And check "✔ Disable symbols browser".

    I had the same issue and this solved it.

  3. It would seem that Codeblocks on Ubuntu is unstable. With Codeblocks 16.01 on Ubuntu 19.04, I see the same issues reported by others — editor freezing, and the application closing suddenly.

    In a message on the Codeblocks forum, a developer responding to the issue says "You've hit some of the nasty bugs I have no idea how to fix", and he refers to an old discussion from the year 2008 on the wxWidgets developer forum about the problem.

    It's a bit surprising that there's a long-standing unresolved bug in a cross-platform GUI library as popular as wxWidgets that causes problems like this, but that seems to be the situation. Unfortunate.

  4. You really don't need CodeBlocks. What you need is g++ compiler for compiling your code. You should have it installed, if not, then:

    $ sudo apt install g++

    For convenience to write code, you can install any text editors such as VS Code (my personal favourite), Atom, Vim, Sublime etc. Just create a new file (say, start.cpp) in some location of your computer (say, /home/<username>/Codes ) and write some code. Then open your terminal in the same location (so in this case, /home//Codes ). Then type:

    $ g++ start.cpp -o start.out   # this compiles your code
$ ./start.out                  # this is how you run it

    If you have some inputs in a file (say, input.txt ) and want to write the output in some other file (say, output.txt), the command is:

    $ ./start.out < input.txt > output.txt

    That is basically the terminal way of cpp. You will probably make mistakes, so I suggest you ask your teacher/someone experienced with terminal. I hope you will never bother to install CodeBlocks again in youe life :)
