Title: Code::Blocks + wxPack...
Post by: StateS on September 08, 2006, 10:45:25 am
I've installed the latest MinGW, Code::Blocks Nightly Build and wxPack on my PC, the version of wxPack includes wxWidgets v2.7.0. How do I use the latest wxWidgets with Code::Blocks? Do I just point it to the directory where wxWidgets is found?

There is no "wxWidgets settings" inside Code::Blocks. You just need to setup your project options (compiler/linker) to the appropriate folders. C::B itself uses wxWidgets 2.6.3 internally but that usually shouldn't matter to you. What counts for you is against what you are compiling/linking.
With regards, Morten.

Right... So I try to create a new "wxWidgets application" project with CodeBlocks... then it asks for the directory of wxWidgets, which I point it to... then it comes up with a whole mess of other things which I don't know what to do... then it says "A matching configuration could not be found in the wxWidgets directory you specified. This means that your project will not build. Are you sure you want to continue with these settings?"... What is it that I'm doing wrong? Before all of this, when CodeBlocks asked where wxWidgets was it had this variable thing in the textbox... something like $(#wx) or something like that... But now it doesn't show up anymore...

Please turn on full compile logging and paste the results here.
Also, system, CodeBlocks version, wxWidgets version

//-- Full Compile Logging --
Settings->Compiler and Debugger->"Other"->Compiler logging = "Full command line".

Please tell us the directory structure of wxWidgets -> where are the includes and where o you have the libs? Then please explain in detail what settings from the wizard you don't understand (or post a screenshot of the appropriate dialog). This will help us to explain.
With regards, Morten.

OK, the part which I don't understand is pretty much the two dialogs after the one which asks you for the directory of wxwidgets. From what I think... It's to build the widgets right? but if that's true then that doesn't make sense cause I already have the widgets built... In wxPack they send a whole mess of prebuilt widgets, dll version, lib version, debug version etc... I have attached the tree listing of my wxwidgets directory and the screenshots of the two dialogs...

When the wizard asks where to find wxWidgets, the default location is $(#wx) - that's good. That means it will use the global 'wx' variable to determine the location. Set the 'wx' global variable to the install location of wxPack - that is the root directory of the wxWidgets tree. The default in the wxPack install is C:\SourceCode\Libraries\wxWidgets2.7

Unfortunately, even when this is correct, the wizard still pops up the warning "A matching configuration could not be found in the wxWidgets directory you specified. This means that your project will not build. Are you sure you want to continue with these settings?". What is the wizard looking for?

The warning can be ignored with wxPack, in some cases. If I leave the default checkboxes checked, on the last page (see screenshot), the wizard sets up the project with the correct paths. It does assume that you'll be linking to version 2.6, you'll need to change the linked library to libwxmsw27u.a.

However, if I uncheck the box for "Use wxWidgets DLL", the generated linker path is "$(#wx)\lib\gcc_" instead of "$(#wx)\lib\gcc_lib".

You can definately use Code::Blocks to make projects that use wxPack, however, it looks like the wizard is looking for some configuration files that wxPack either does not have, or does not have in the right place.

If the authors of the wizard would post exactly what they are looking for, as far as configuration, and it is determined that that is the best approach, I'm sure wxPack could be updated.

Hopefully, in the future, these two tools will work better together.

You can disregard that warning. I am not sure what the wizard is actually looking for, but you do need to set the Global Variable to the base directory of the wxPack install.

Example:
Code
C:\SourceCode\Libraries\wxWidgets2.7

1. Then once it creates the files open the 'Build Options' ans click the top level target.
2. Choose the 'Linker' tab.
3. Change the 'Link Libraries' to have a 27 instead of the 26.
      Example: libwxmsw26u.a -> libwxmsw27u.a
      (See screenshot)

So basically I can just go ahead and click next in everything and it will work fine right? All i have to do is modify that linker setting?
Title: Re: Code::Blocks + wxPack...

This is for the "Using wxWidgets DLL" checked.

I guess when you un-check the "Using wxWidgets DLL" it requires you to change the 'TopLevelTarget -> Directories -> Linker' tab from:
Code
$(#wx)\lib\gcc_
To:
Code
$(#wx)\lib\gcc_lib

and also add to 'TopLevelTarget -> Linker -> Link Libraries'
Code
comctl32
ole32
oleaut32
uuid

You can look at the attached screen shots for some details on the Wizard setup, Bug in wizard generated directories, and the link libraries needed.

Nice job. I haven't tested it yet, but there are many problems with choosing vc as your compiler. To see all the steps required to get the wxWidgets wizard up to working condition with Visual C++ please look at the tutorial here (http://wxpack.sourceforge.net/Tutorials/CodeBlocksWxWizardVC).

Please take special note of the
Quote
Zc:wchar_t-

(More information: This setting should be in the Compiler|Compiler Flags tab, but it isn't, so we are adding it manually.)

The difference is that VC8.0 turns this setting ON by default and in VC7.1 you can just turn it on. So I imagine that this was an oversight when making the VC8.0 support. I can make a separate thread for this issue if you think that is necessary.

Ok, so what I want to do is use the release version non-unicode (cause I want compatibility for Windows 98 as well)... RJP will that configuration you show me allow me to use this version (the release non-unicode version) of the wxWidgets libs?

Yes all you need to do is make sure the 'u' is off the link library name. (The 'u' stands Unicode)

Example:
Code
wxmsw27u
To:
Code
wxmsw27

This is the way that all the wxWidgets library is setup.

What about in the wizard configuration... The one with all of the checkmarks. I should probably deselect the debug version, leave the release version selected and in the second wizard dialog I should uncheck everything but the "Create and Use Precompiled Headers" right?

I think that one setting was left forgotten... correct me if I'm wrong... but in the TopLevelTarget>Directories>Compiler there is a setting there that is like so: "$(#wx)\lib\gcc_\msw" Shouldn't it be changed to this (in my case I'm using actual libs and not dlls): "$(#wx)\lib\gcc_lib\msw"?

here are some attachments so you can see what I'm talking about...

Don't be afraid to try these settings out. If they don't work try some more. That is the best way to learn.

I attached screen shots of every wizard screen so you can just duplicate the details.

Have you ever wrote software before? I am not trying to be mean at all, it is just that you are asking some fundamental software development questions. It is OK, but an idea of what you have done before would help tailor the responses for you.  :D

I have never done anything professional if that is what you are asking... My dream was to become a software engineer, but after I saw the maths and physics that I had to tackle and saw how poorly I was doing in these classes, I saw that my dream that could not become reality... So I changed to a Mutimedia based course (Photoshop classes and the like) where there is no Math or Physics. I start in a couple of days...

I have programmed in Visual Basic, Pascal, and C, the first two are the ones that I am better at. The thing is that I have never programmed in C++ before and all of these configurations that I must do to get the IDE to work correctly and stuff is kinda new to me... C was never really my forte, that could be becuase I am forced to study it in a language that is not the one I grew up with (I'm an imigrant USA->Portugal, trust me Portuguese is way harder to understand than English is...), actually it could be the reason that I am bad at math as well, up until the point that I imigrated I always had Bs and As in math with the least amount of effort...

Where was I? ... ... Oh yeah... I'm pretty new to C++, I'm going to learn it basically while I program, and since I never compiled almost anything other than the programs that I had made, building wxWidgets and configuring compilers is still pretty new to me. The only type of programs that I have done before are the simple ones, exercises which I was told to do. Basically... apply the algorithm that they supply, or make a program from the description given to you. Those were the types of programs that I did in C and Pascal... In Visual Basic I did more programs with databases than anything else, most of which were games like who wants to be a millionare or a lottery emulator (it doesn't generate lottery numbers... you just select a few numbers and hope to get some of them right).

I am thankful (I'm almost sure that that is spelled with two "l"s...) that all of you here have been very patient with me, I know that my constant questioning can become quite tiresome and annoying (as RJP might already know from another forum :P), it's just that I like to always get a second opinion... Sometimes I might be very sure of something, but I don't try it because I'm afraid that something bad might happen, so I ask for a second opinion... I guess I'm just a coward afraid of the consequences of my choices...

Anyway, I just compiled an example program and everything went fine. Here is what the log had to say:

-------------- Build: Release in CDMaster ---------------
Precompiling header: wx_pch.h
Compiling: main.cpp
Compiling: app.cpp
Linking executable: bin\Release\CDMaster.exe
Process terminated with status 0 (0 minutes, 15 seconds)
0 errors, 0 warnings

Great to here that you got it working. :!: :!: :!:

Well you have triggered fixing the wizard so that it will work for everybody, so you did a good thing. But knowing this is your first program with C++ the questions are understandable. Not every project needs to be tweaked like I have described, so don't give up.

Remember that you can do anything your REALLY want to, so if Software Engineering is your goal, STICK WITH IT! :D

Ask questions just give some point of reference for people so that they know you are not just trying to be annoying. You will most likely get better help. :wink:
