wxFormBuilder generated classes and using them within code::blocks

[blue orb]

i can't get the files generated by wxFormBuilder to work. when i add these wfb-generated .cpp and .h files to the active project, in code::blocks, i get more errors. do i need resource files? what are rs files?

btw, wxWidgets projects compile/run fine and all is ok there. so that's something!

however, wxsmith content still won't compile and is giving error messages about missing headers.

i have now tried three seperate compilers (minGW 32-bit, minGW 64-bit and that dw2 gcc compiler.

i am a noob, yet this just gets more and more complicated...

Error messages have meaning; I suggest reading them.
You might even post them.

Your problem is likely an Compiler/Linker problem instead of a Code::Blocks problem; without the errors, I can only guess it is user caused problem.

i presume it is something fundamental that i am doing wrong. the problem seems to be the missing header files/other. i am just about stuck... any ideas?

thanks!

I thought we went through all this yesterday? You have to tell codeblocks the location of the wxwidgets installation!

And BTW, names beginning with double underscores or underscores and uppercase letters are not allowed in user C++ code - they are reserved for the C++ implementation.

[MortenMacFly]

...in addition: Having characters like "+" in the path might sooner or later cause errors, too. For development, I'd suggest you prefer simple path names (letters and numbers), probably even without spaces to avoid conflicts across platforms. Of course, this does not apply for the runtime version of your application.

[blue orb]

okay, as said, a wxWidgets project works fine...

but a wxsmith project still doesn't compiile.

i have told code::blocks where the wxWidgets (wxPack) is and that works fine with a new wxWidgets project. alas, wxsmith projects still don't compile.

the differences between wxWidgets and wxsmith are beginning to blur on me.

i might give this up

[Radek]

wxWidgets headers have not been found at all, even if they are in "<>". Check what is produced by wx-config --cxxflags and wx-config --libs. If your headers (and libraries) are elsewhere, add paths to your headers (and libraries) to Build Options of your project. You can also create a "custom project" which will be wxWidgets project along with the right paths to your headers. The problem does not seem to be caused by wxFormBuilder.

The underscores are okay. They aren't around names of variables but around #define symbols, where underscores are used frequently.

[zabzonk]

> The underscores are okay. They aren't around names of variables but around #define symbols, where underscores are used frequently.

Perhaps you should read the C and C++ standards before giving advice like this? Names like that are NOT OK. To quote from the C Standard:

> All identifiers that begin with an underscore are always reserved for use as macros and as identifiers with file scope in both the ordinary and tag name spaces.

and:

> All identifiers that begin with an underscore and either an uppercase letter or another underscore are always reserved for any use.


Here "reserved" means "reserved for the C (or C++) compiler implementers".
