wxWidgets on OS-X no work!

[Neal M]

Whenever I try to make a wxWidgets project, Code::Blocks gives me a crap load of compiler errors just trying to run the default Hello World (errors in attached text file).

I inquired over on the wxWidgets forum and was told that I appear to have built the wx package correctly and the issue is apparently that Code::Blocks isn't configured properly to work with wxWidgets.

I'm using C::B 13.12 (the latest version available for OS X) and wxWidgets 3.0.4 on OS X 10.13.2 (High Sierra).

So, what is the output of wx-config from the command line?

Code

wx-config --list

I can't get the wx-config script to run, that's my other problem.

Neals-MacBook-Pro:wxwidgets-3.0.4 Neal1$ ls wx*
wx-config-inplace.in   wx-config.in      wxwin.m4
Neals-MacBook-Pro:wxwidgets-3.0.4 Neal1$ wx-config --list
-bash: wx-config: command not found
Neals-MacBook-Pro:wxwidgets-3.0.4 Neal1$ wx-config.in --list
-bash: wx-config.in: command not found
Neals-MacBook-Pro:wxwidgets-3.0.4 Neal1$

This seems like the unpackaged source dir.
Probably you need to build the library first.

[Neal M]

Well I did the build procedure according to the installation instructions.
The sample apps all seem to work, which suggests that the build went okay, at least that's what I was told in the wxWidgets forum.

I don't know what else do.

[sodev]

Install your build.

[Neal M]

Install your build.

Well if I knew how to do that I wouldn't need to be asking for help here. Can you tell me how this is done?

[sodev]

If you built the source tarball using the usual configure && make it is

Code

sudo make install

or whatever OS-X uses as command to become root.

[Neal M]

OKay, I tried sudo make install, and it spat out a bunch of text, said it had installed, C::B is still not happy. The wx-config script runs now though.

Neals-MacBook-Pro:wxwidgets-3.0.4 Neal1$ wx-config --list

    Default config is osx_cocoa-unicode-3.0

  Default config will be used for output

And

Neals-MacBook-Pro:wxwidgets-3.0.4 Neal1$ wx-config --cppflags
-I/usr/local/lib/wx/include/osx_cocoa-unicode-3.0 -I/usr/local/include/wx-3.0 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL -D__WXMAC__ -D__WXOSX__ -D__WXOSX_COCOA__

Now you need to post a full Code::Blocks rebuild log.

And, hopefully someone will see the cause of C::B build problem.

Here's the rebuild log:

[stahta01]

Try adding these defines to your project. Note, the better option would be using wx-config in your project settings; but, I am guessing you do not wish to do that.  Tim S.

Code

_FILE_OFFSET_BITS=64 
WXUSINGDLL
__WXMAC__ 
__WXOSX__ 
__WXOSX_COCOA__

Edit: Add steps to add the defines.

Project -> Build Options
Tab: Compiler Settings
Sub-Tab: #defines

[Neal M]

Well that produces a different set of errors, so I guess that's progress...

I'm open to trying the wx-config option, I'm just not very experienced with this sort of troubleshooting.

[stahta01]

Can some Linux user walk the OP thru using wx-config in a project?

To use wxWidgets you have to supply the proper compiler and linker options. Because it is not so simple to just add the include directory and add one library you can use the wx-config script to get the required settings. You seem to have added some settings by yourself, remove these first.

Then go to the project settings and add under "Other compiler options"

Code

`wx-config --cxxflags`

and under "Other linker options"

Code

`wx-config --libs`

If you did build wxWidgets not as monolithic library but as individual libraries you can further restrict to link only to the libraries you actually use, but for this you need to check the wxWidgets documentation which ones you are actually using, a minimal GUI application at least requires this:

Code

`wx-config --libs core,base`
