Mingw compiler

[Neville Dastur]

I have recently got fed up with booting up a windows virtual box just to
compile the windows version of my app, so I checked out the MinGW
compiler on Linux. I have pretty much everything working except for
wxUSE_ON_FATAL_EXCEPTION.

I have always used this in my applications as I would like to log and
report unhanded errors, but it seems to be incompatible with MinGW. I
know wxUSE_ON_FATAL_EXCEPTION is set to zero if MinGW is the compiler,
but can't work out why. Is this something I need to ask the MinGW devs
about? Does it still apply to the latest MinGW releases. Should I drop
the use of wxUSE_ON_FATAL_EXCEPTION altogether?

Thanks in advance.

Partly answering my own question, is this article a possible solution?

This does look very promising. If anybody can

1. Contact the author of this code and ask him for a permission to include
it in wx under wxWindows licence
2. Actually integrate it into wx and make a patch (please see
http://trac.wxwidgets.org/wiki/HowToSubmitPatches) with the necessary
changes

it would definitely be very welcome.

But as it stands wx supports wxUSE_ON_FATAL_EXCEPTION under Win32 only
with compilers with built-in support for SEH which, unfortunately, means
that mingw32 is not supported.

We use a Windows function that allows doing a log before the OS closes
the application. I think you can't do anything more after
this function is called.
This is the code:

inside MyApp::OnInit we insert this line

SetUnhandledExceptionFilter(filter);


Before MyApp::OnInit we define the following function:

LONG __stdcall filter(EXCEPTION_POINTERS* p){

wxString text;
text.Printf("Unhandled Exception Code : %s",
p->ExceptionRecord->ExceptionCode);
Log(text);

exit(-1);
}

where Log is a custom function we use for logging.


regards,


Justino.
