wxWidgets Hello World! fails to build
« on: July 22, 2023, 04:47:21 am »
I created a C++ console project. It was 'Hello World'. Both debug and release projects compiled fine. I then replaced the code in main.cpp with the code from wxWidgets 'Hello World'. Custom variables and search directories were modified. Neither Debug or Release projects compiled.

Has anyone been successful in building wxWidgets 'Hello World' with any gnu/gcc compile version, with or without using any modifications to the project? Any suggestions would be greatly appreciated!

My suggestion is post a build log in code tags if you want help.

I am building an custom wxWidgets to see if my current CB project will work.

It will be building for a few more hours.

Edit: I had to add two missing $(WX_CFG)
Code

Well, it's pretty obvious that you do not tell the linker about the wxWidgets libraries needed and where to find them.

Using console template as a starting point for a GUI library project seems rather odd choice, particularly when C::B ships with a wxWidgets project template wizard which makes using wxWidgets with C::B trivial.

Your build command line should look like something like this, where I bolded some of the important parts you are missing

-------------- Build: Release in testwx321 (compiler: msys2-mingw-w64-x86_64)---------------

windres.exe -IC:\dev\libs\wxWidgets-3.2\include -IC:\dev\libs\wxWidgets-3.2\lib\gcc_dll\mswu -DwxUSE_DPI_AWARE_MANIFEST=2  -J rc -O coff -i C:\dev\TESTWX~1\resource.rc -o obj\Release\resource.res

Output file is bin\Release\testwx321.exe with size 86.50 KB
Please notice there is a windows resource file, without having it and it including wx.rc, your application will not have a compatibility manifest, which will result in your application looking weird and some issues (e.g., bitmap transparency in toolbar).
Also, without -mwindows, the application will show a console, which is generally not welcome in a GUI application.

Once again, I suggest not trying to reinvent a wheel and using the C::B wizard shipped with a nightly (or the one from my guide).

@PB:
What tells you that 'wxWidgets Hello World!' should be handled as a wxWidgets GUI Project. I've just attempted to use the wxWidgets template to build a wxWidgets GUI Project. I've replaced the code of appmain.cpp with the code of 'wxWidgets' Hello Wold!'. The build log follows:

Code

Using the wxWidgets template involves several dialogs, each with several choices. Is this what you were talking about? I'll have to work longer on this project!

Much appreciation!

I think it would be easier if you followed my guide linked above, or at least its chapter 4.8 which explains what is actually needed in a C::B wxWidgets project. But the wizard should work as well, as long as you know what you are doing.

Anyway, I see at least two issues with your last build:
1. The library folder is different than before (gcc_dll vs gcc_dll64): are you sure your build (including the build-specific setup.h) is really there?
2. You attempt to link against the monolithic wxWidgets library (-lwxmsw32u): is your wxWidgets build really monolithic (MONOLITHIC=1) and not the default multilib?

If you do not want to follow a guide, I strongly advise looking at least at the official docs. IMO, the trial and error is not the best way here, wasting lot of time and effort.

I'll take a look at your guide (took a quick peek at it after your last reply). Yes, the library is monolithic and WX_CFG=64.

Your guide is a tutorial rather than a reference manual. Just what I need!

Thanks again!

I followed the guide. Used compiler from CB13318, Recompiled wxWidgets libraries to  multilib. Build log for debug target follows:

It seems you did not follow my guide. For example, it makes no sense to pass C++ compiler this (the second one does not even exist)
Code
-DwxUSE_DPI_AWARENESS_MANIFEST=2 -DwxUSE_AWARE_MANIF=2
While this should do no harm, it can be seen that some steps were missed or done incorrectly.

More importantly, the command line is a mess
Quote
g++.exe -pipe -mthreads -DwxUSE_DPI_AWARENESS_MANIFEST=2 -DwxUSE_AWARE_MANIF=2 -D__GNUWIN32__ -D__WXMSW__ -DWXUSINGDLL -DwxUSE_UNICODE -DwxUSE_DPI_AWARE_MANIFEST=2 -D__WXDEBUG__ -IC:\wxWidgets-3.2.2.1\include -IC:\wxWidgets-3.2.2.1\lib\gcc_dll64\mswud -c C:\Sandbox1\Test\TestMain.cpp -o obj\Debug\TestMain.o
vs
Quote
g++.exe -LC:\wxWidgets-3.2.2.1\lib\gcc_dll -o bin\Debug\Test.exe  obj\Debug\TestApp.o obj\Debug\TestMain.o obj\Debug\resource.res -mthreads -mwindows  -lwxmsw32ud_core -lwxbase32ud -mwindowss
why are you using two wxWidgets library folders, this is obviously wrong?

Sorry, but it is pretty clear you did not follow the guide as the wizard would have set the folder correctly (and also added the resource file).

Did you at least, as instructed, build and run the minimal sample to check whether the wxWidgets library build was successful?

You should also read the build output: if you did, you would have noticed the problems as they are hard to miss.

@PB:
i had compiled your tutorial's sample a few times accounting for multiple occurrences of wxUSE_DPI... i deleted that sample and started over. Your tutorial's sample was for 32-bit machines. I made a couple of modifications to make that sample compile on a 64-bitplatform. I obvious didn't change the link command correctly. Also your tutorial  said to set a particular compiler flag,  but the available compiler flags weren't available. The new build log follows:
Code

collect2.exe: error: ld returned 1 exit status

Is what I missed apparent?

The number of compilations has no effect on the number of occurrences of a define. Still, the point was this define belongs to the resource compiler, not the C++ compiler, as is clearly explained in the guide.

Your tutorial's sample was for 32-bit machines. I made a couple of modifications to make that sample compile on a 64-bitplatform. I obvious didn't change the link command correctly. Also your tutorial  said to set a particular compiler flag,  but the available compiler flags weren't available.
My guide is for the 64-bit compiler (are we even talking about the same document?), moreover, the bitness does not matter at all here and everything works out of the box irregardless. I also do not see how it would be possible for the available compiler flags to be unavailable?

Looking at the build output, it is pretty obvious you are still mixing library folders and did not follow the guide, letting the wizard set everything for you.

Unfortunately, it seems that my guide is not a good match for you and you need to use another, better, resource. Sorry for leading you the wrong way and good luck in the future!

@PB:
I apologize for wasting your time in you trying to explain to an [old] newbie how your tutorial builds the correct sample right out of the box. I'll read your tutorial completely, but there will be no more correspondence about this subject.

Thanks again for your efforts in trying to explain to an [old] newbie how wxWidgets projects can be built.
