Code::Blocks Starting Issue (OpenSuse 12.3)

[CudRa]

Hello, I'm new here and I have a problem with Code::Blocks under OpenSuse 12.3. (and I'm new to OpenSuse / Linux as well...).

When I try to start Code::Blocks for the first time after a reboot, it works fine. But when I close it and then try to open it again, I just can see a new tab in
the window-bar on the bottom of the screen but nothing happens. I also noticed that if I close Code::Blocks after I started it, it just closes the Window of Code::Blocks
but it doesn't terminate it's process (the process still runs as I can see when I type "top" in the terminal or press CTRL+ESC). I found out that the standard settings ("Enviroment") allows
only one instance of Code::Blocks at the same time so I think thats the reason why I can not start Code::Blocks a second time because the process of the first instance is still running.
I tried do uncheck this option so that more instances are allowed, but Code::Blocks doesn't save my changes and this option is checked again when I startd Code::Blocks again after a reboot.

I tried the steps mentioned in this link: http://forums.codeblocks.org/index.php?topic=8520.0;prev_next=next. When I delete the file "/tmp/Code::Blocks-<your-user-name-here>"
I am able to start Code::Blocks again without to reboot my computer, but then this file is created again and the next try to open the program fails.
I also tried to edit the  file "default.conf" in "~/.codeblocks/" as mention in the link, but I couldn't find the entry "<SINGLE_INSTANCE bool="1" />".

Does someone has the same problems or even a solution for this problem?

(I have OpenSuse 12.3 and Windows 8 installed (paralell) on the same machine. Does that may be a problem?)

Thanks in advance and sorry for my bad english  !

Which version of C::B do you use ?
Can you try to start C::B from a console (just type codeblocks) and look at the output if you try to close C::B and see if there is something relevant ?

I had the same problem on Slackware.  Found disabling the code completion plugin stopped it from happening.
If you run it from a terminal emulator as suggested and wait till the process terminates it should print error messages indicating the cause.

I use Code::Blocks version 12.11.

When I start C::B from the console and then close C::B again, I get the following output on the console:

When I start C::B with "sudo codeblocks" in the console, I get the following output:

Code

Error: Unable to initialize gtk, is DISPLAY set properly?

(I use OpenSuse with KDE-Desktop)

But when I start a root shell and then type "codeblocks" to start C::B, it starts correctly (without the error above), I can change any settings and they were really saved. When I then close C::B (with the code completion plugin enabled or not), the process is terminated correctly.

It's a strange behaviour of C::B...

Code

Error: Unable to initialize gtk, is DISPLAY set properly?

That's normal behaviour, it's not allowed to access your display, even not for root.
That's by design and has nothing to do with C::B !

If you type

Code

xhost +

before

sudo codeblocks

it should work also.
You should forbid display access with

Code

xhost -

after closing C::B for security reasons, even if it is not a real problem on a single user system (In most cases).

But when I start a root shell and then type "codeblocks" to start C::B, it starts correctly (without the error above), I can change any settings and they were really saved. When I then close C::B (with the code completion plugin enabled or not), the process is terminated correctly.

It's a strange behaviour of C::B...

I think it's a strange behaviour of you system, not C:::B.
The output shows nothing real serious, even the GTK-Critcals are normally harmless, they come from a wxWidgets bug, and that's not a C::B issue, as we do not maintain wxWidgets. In most cases it's done by a maintainer-team of the distro you use.
That does not mean, that we do not try to work around such issues, but it's sometimes not easy.
And we have issues and bugs in our sources also, of course.
That's normal for complex software, and we can not avoid it, sorry.

Nevertheless, did you try to remove (or better rename) the whole (hidden) .codeblocks folder in your home-directory, when no instance of C::B is running.
Starting C::B should create it from scratch with default values, all your user settings will be lost, but you can restore some of them with cb_share_config.

[CudRa]

I renamed the folder .codeblocks and started C::B again.
The folder was created again as you mentioned, but unfortunately that didn't helped...

Thank you for the explanations
I understand that it may be a problem with my system and
I hope this problem will be fixed eventually.

[CudRa]

Hey, I found a solution for this problem I think...

I started a root shell and gave me (my user-acc) with the "chmod"-command the read, write and execute-rights for the file "/usr/bin/codeblocks".
If I start C::B now, everything works fine!

Can you tell me if this is a "good" solution, or if this is something like a "workaround" or "hacker-like"? ^^

Now I'm just happy that it works

[Jenna]

The executable should have 755 filemask (read-and executable by owner, group and others, writable just by the owner, user and group should be root).
If you need write access on the executable, to run it correctly, your system must be seriously broken.

[CudRa]

Ok, I just changed the settings of the executable exactly as you described it...and it works, too!
I don't know the settings as they were before... Could I reproduce this phenomenon by deinstalling and
then re-install C::B? Or are the x/r/w-permissions for the executable saved even when reinstalling C::B?
I would be interested in knowing how the x/r/w-permissons were set-up before...
