wxJSON and wxWidgets 3.0.0

[jm130794]

Hello,

When I use wxJSON 1.2 with wxWidgets 3.0, I have this error when I run my
program :

./a.out
/usr/local/include/wx-3.0/wx/strvararg.h(451): assert "(argtype &
(wxFormatStringSpecifier<T>::value)) == argtype" failed in

My program :

#include <iostream>

#include <wx/string.h>
#include <wx/wfstream.h>
#include <wx/mstream.h>

#include <wx/jsonval.h>
#include <wx/jsonreader.h>
#include <wx/jsonwriter.h>

using namespace std;

int main()
{
wxJSONValue root;
wxJSONReader reader;

wxFileInputStream inStream("values.json");

int numErrors = reader.Parse(inStream, &root);
if (numErrors > 0) {
cout << "Error" << endl;
return 1;
}

return 0;
}

and values.json :

/***************************
This is a C-style comment
***************************/
{
// this is a comment line in C++ style
"wxWidgets" :
{
"Description" : "Cross-platform GUI framework",
"License" : "wxWidgets",
"Version" :
{
"Major" : 2,
"Minor" : 8,
"Stable" : true
},
"Languages" :
[
"C++",
"Phyton",
"Perl",
"C#/Net"
]
}
}


Any ideas ?

Thanks,

Looks like a bug in wxJSON (as there are no wxPrintf()-like functions call
in your own code). You need to break into the debugger when the assert
fails and find the wrong format string and correct it.
