Settings don't get saved (svn 4454)

[johne53]

A few days ago I installed svn 4454 (via the rpm package for OpenSuse). Since then, I'm finding that changes to my IDE aren't being reliably saved. For example, if the selected build target is Debug and I change it to Release, next time I start C::B it will still be Debug. Similarly if I use Settings->Compiler and Debugger and I add a new search directory, the new setting has disappeared next time I re-start C::B. Can anyone else confirm this before I report it as a bug?

Also, is there a way to manually save these kinds of changes?

This is not the bug, but only a symptom of the bug. If settings are not saved, this means that a crash occurs after you tell the application to quit, but before ConfigManager is deleted (settings are saved in its destructor). To narrow down the source of the crash, please try disabling all contrib plugins first, and if that does not help, disable the "core" plugins one by one (start with CodeCompletion). Also, if you have a RPT file, it may be helpful to see that one.

None at the present time (and not likely in the future, although it would probably be easy to implement).

Yes - that's pretty much what I suspected. I haven't installed any plugins personally but I'll happily try disabling the standard ones if you can tell me where to do it. Also, what is an RPT file and where would I find it??

This one is confirmed. This happens as the default target loaded from layout file is not used to update the Target Combo and the Menu items.

[johne53]

In fact I've just realised that if I change an IDE setting, I don't see the dialog box any more telling me that my layout has changed and asking if I want to save the new layout. So it's not even getting to that stage.

Is there a way of going back to my old version temporarily? I don't like having bugs that cause things not to get saved.

If you compile codeblocks from svn you can checkout older versions by explicitly tell the svn-revision:

Code

svn checkout svn://svn.berlios.de/codeblocks/trunk /path/to/your/codeblocks/source/ -r revision_you_want --non-interactive

Thanks Jens. Unfortunately I've never managed to build C::B from source. If I try to compile the Codeblocks-unix project I get an error at line 9 ofPlatWX.cpp (wx/wx.h can't be found). I've tried finding it with find but I don't seem to have it. On the other hand, if I try to compile the Codeblocks project I get the error cc1plus: error: unrecognized command line option "-mthreads" I've never managed to work out what's wrong....

It means you don't have wxGTK-devel package installed.

I guess you tried with the project file meant for Windows. -mthreads is applicable for Windows only. It won't work on Linux. So don't try to use this project file. It will not work out-of-box.

[johne53]

It means you don't have wxGTK-devel package installed.

Sorry - did you mean wxWidgets-devel? I couldn't find much on Google about wxGTK_devel. Can you point me towards a site where I can download it (I'm running OpenSuse 10.2, so Yast or RPM would probably be favoured).

[Edit...] Oops, sorry. I found it (I typed it wrong into Google)

Do you know what version it's up to? The latest I can find is 2.6.3.3 but I thought it was at around 2.8.x.x

[thomas]

I'll happily try disabling the standard ones if you can tell me where to do it.

If you launch Code::Blocks with --safe-mode (type that in the "Run..." box or in the shell), it starts without *any* plugins at all. Other than that, you can disable plugins one by one from the "Manage Plugins" dialog (found in the "Plugins" menu).
Also, there is the really hard way of simply deleting the respective shared library from the plugins folder. As you can always restore them by hitting the "build" button, there's not much to lose really.

Also, what is an RPT file and where would I find it??

That is a file containing a stack backtrace, which can be used to pinpoint a crash in many situations. It is created when the application crashes and can normally be found in the same directory as the application or in your home directory, and called codeblocks.rpt.

You should use at least wxGTK-devel-2.8.4 if you want to use wxGTK-2.8.x. Otherwise you can install wxGTK-2.6.3 package.

Or just compile it on your own. I assume, your PC has autotools, gcc installed.
1) Download wxGTK-2.8.4 source from wxWidgets site.
2) Extract it to a folder.
3) Open shell and type the following command to configure wxGTK (this is what I do).

Code

./configure --disable-debug --enable-shared --enable-unicode --enable-monolithic --with-gtk=2

4) Now do make and make install. Your PC is ready to compile C::B.

Also, what is an RPT file and where would I find it??

On Linux, you'll find it under /tmp folder. Look for the folders starting with codeblocks_dbgrpt-* (where * is several numbers). Inside that folder you'll find an codeblocks.xml file. That will contain the crash report.

Edit 1:

You can download wxGTK-2.8.4-devel from the following link.

http://download.opensuse.org/repositories/home:/TheTuxKeeper/openSUSE_10.2/i586/

Thanks. Forgive my ignorance - but is wxGTK-devel the same as wxWidgets-devel ?

(the library shown in your link was wxWidgets-devel).

wxWidgets has more than one type; wxGTK is the type needed by Code::Blocks under Linux.
Note, wxWidgets-devel is needed to compile Code::Blocks.

The file wxWidgets-2.8.4-11.1.i586.rpm is most likely needed to run Code::Blocks.

Sorry for creating that confusion.

Download the wxWidgets-devel package to compile C::B.

[johne53]

Okay, I installed wxWidgets2.8-devel. Now when I compile I get an error at line 42 of /usr/include/wx-2.8/wx/defs.h

error: #error "No Target! You should use wx-config program for compilation flags!"

Is this simply a matter of a missing preprocessor directive or do I need to run some external program to configure something..?
