wxWidgets Hello World! fails to build

@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:

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!

PB:
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.

@PB:
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:

What have I missed?

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
--- End code ---
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

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.
