The webhost is having some problem with their server which is keeping this site down sometimes. I am very sorry if you’ve encountered any issue accessing this site.

I am already making necessary arrangements to move this blog to another paid host so that I can get better service. But the process will take about a weeks time.

Till then you may face some problem reading my blog. But please keep visiting.

Hello Everybody,

There has been couple of significant changes to wxWidgets project wizard of Code::Blocks. The update will help advanced users who want to debug their application in Debug mode but linking with Release library of wxWidgets. Yes! this is now possible but only for GCC. Other compilers may not support this feature and thus it has been internally disabled.

Changelog:

• Set Target Types option has been renamed to Configure Advanced Options. (See screenshot 1)
• Now wizard can setup debug target using Release wxWidgets lib and without __WXDEBUG__. Please remember that this is available only for GCC in Windows. (See screenshot 2)

This option was requested by several developer of Code::Blocks. This option will enable a developer to compile application in debug mode (using -g flag to be particular) but using release lib of wxWidgets to avoid mixing of bugs. Please remember that this option will not work for any other compilers other than GCC.

You may be aware that I was working on improving the old wxWidgets Project wizard. I had released the 7th revision of the new wizard on 29th January 2007.

Now the Code::Blocks development team has merged the 7th revision with their latest Nightly Release (Released on 30th January 2007). That means now you don’t have to manually install it.

Any further revisions / modifications will be merged to the main repository directly. So there won’t be any code release through my blog. But you’ll be kept up-to-date on the changes made.

If you are using any old Nightly Build of Code::Blocks, then I would request you to upgrade to 30th January 2007 Nightly or Onwards to get the benefit of latest wxWidgets Project Wizard. Nightly builds are available from the following forum.

Have a nice experience with Code::Blocks.

Revision 6 of wxWidgets Project wizard is now available. This revision comes with several new features.

Changes:

• Added support (partial) for Linux and Mac (Untested). It’s now possible to select different wxWidgets version present in Linux system.
• Added option to select Static/Dynamic, ANSI/Unicode build of wxWidgets in Linux.
• Added option to select Application Target Type in Windows (For Advanced users only)
• Wizard now checks the presence of wx configuration, selected for project, precisely in Windows. Expect almost No false warning.
• Couple of minor fixes and code clean-up.

New options available in Linux

Check the Highlighted option to change target type

Change Target Type here, but be cautious.

Tested in:

• OpenSUSE 10.2 with GCC 4.1.2, wxGTK-2.6.3 & 2.8.0 Dynamic-(Debug/Release)-Unicode-Monolithic build of lib.

Known Issues:

• Does not check the presence of wxWidgets lib in Linux system. So be careful to select correct lib configuration otherwise the generated project will fail to compile.
• Checked with Monolithic builds in Linux; it may give you trouble if you are using non-monolithic builds in Linux.

Important Note:
Please be careful while changing Target Type. For GCC there shouldn’t be any problem. But with BCC you’ll have to manually change some compiler settings otherwise it won’t link.

The new features may come with Gift of Hidden Bugs. Please share that gift once you get that. Download the latest release from the following link.

Also please post your comments, feedbacks.

Hope you’d enjoy this new release.

I have been posting the Modified wxWidgets Project wizard for the past couple of weeks. But there seems to be one missing point. How to install them? The installation details are already in the forum. Still I’m posting them for your convenience so that you do not need to scroll through the entire thread. The follwing procedure is applicable for Windows only.

First, download a Nightly Build of Code::Blocks from the following forum. Read the latest post and download the latest Nightly using the link provided in that post.

http://forums.codeblocks.org/index.php?board=20.0

Now download two more files from the following link.

wxWidgets Runtime DLL

MinGW Runtime

Now extract all the files to a folder, e.g. C:\CodeBlocks

Run the codeblocks.exe to launch Code::Blocks IDE.

To Install the Modified wxWidgets Project Wizard, please follow the following steps. Download the latest revision of project wizard from the following post.

wxWidgets Project Wizard – Revision 7

You’ll find that the zip file contains a folder named wxwidgets which contains some file. Now extract the folder to following location <Code::Blocks Dir>\share\CodeBlocks\templates\wizard folder and overwrite the existing wxwidgets folder and files inside that. If you wish you may keep a backup of existing folder.

That’s it. You have now successfully installed new wizard.

Please remember that it is a Development Release and there might be bugs.

Here comes the Revision 5 of the modified wizard. Only one new feature has been added.

Changes:

• Supports Microsoft Visual C++ 7.1 Compiler.
• PCH support is activated for MSVC 7.1 compiler.

Few Important Notes:

• Wizard assumes that Multi-threaded Dynamic C and C++ Runtimes are being used. If you are using wx lib statically linked with C Runtime Library (CRT) you should make couple of changes in the libraries added. I’ll discuss it later in this post.
• Wizard generated projects will fail during linking if it doesn’t find msvcprt[d].lib

I’ve tested the wizard for MSVC 7.1 with wxPack. I’ve found that static libraries are statically linked with CRT. That may generate the following error if you are using this wizard with wxPack’s static libs.

wxbase28d.lib(baselib_datetime.obj) : error LNK2001: unresolved external symbol _timezone
OLDNAMES.lib(timezone.obj) : error LNK2001: unresolved external symbol _timezone
OLDNAMES.lib(timezone.obj) : error LNK2001: unresolved external symbol __timezone


To solve this, do the following; Go to Project > Build Options menu, then go to Linker tab. Remove msvcrt[d].lib from Linker Libraries section and add libcmt[d].lib. Also remove /NODEFAULTLIB:libcmt[d].lib from Linker Options section.

The wizard has been merged with Code::Blocks repository and it is now available with latest nightlies.

If your installation does not have msvcprt[d].lib then visit the following websites to get more details on how to create it.
