Using CB and CB Projects?

Yes.

Is there another method? I'm dreaming of cmake.

--- End quote ---

Another poster was trying to add cmake as a build method (I have no idea which OS); I never got configure/make build to result in a working C::B.

stahta01:
What patches are you using on the CB project? And/or, which CB Projects are you using?

I got the same error after this patch/change. Tim S.

Now researching the proper code fix.

Looks like the changes are too much for me to figure out and do quickly.

Edit: Found some 3 year old work updating it to wxWidgets 3.2.x.y; could not find the more recent work likely was on my hard-drive that crashed.

--- End quote ---

For better or worse, wxString is convertable to char* by default, see https://docs.wxwidgets.org/stable/overview_string.html#overview_string_implicitconv

Perhaps you built wxWidgets with wxUSE_UNSAFE_WXSTRING_CONV defined to 0?

--- End quote ---

Noop, wxUSE_UNSAFE_WXSTRING_CONV is 1; but both wxUSE_STL and wxUSE_STD_STRING_CONV_IN_WXSTRING are also one.
