what is the problem? Topic is solved

[candid_1120]

I have compile the code of Ryan Norton and make the dll,but it is be crashed when I load it(click the L button of mouse);

This is the exceptional:

Debug Error!

//...

The value of ESP was not properly saved across a function a call.

This is usually a result of calling a function declared with one calling

convention with a function pointer declared with a different calling

convention
(Press Retry to debug the application)

What is that problem and how to solve it? Thanks a lot.

Well, to answer your question we'd need to know what *code* you refer to. Most of us know Ryan, but I have absolutely no clue what code you are refering too.

And please post compiler version, wxWidgets version, platform, etc. as well.

Sounds like you are using stuff like cdecl (?? can be a delphi directive) or exporting the functions one way (stdcall etc) and trying to call them with reverse argument order. Which can cause a big mess.

Make sure your header file matches the way the function call is exported.

The same error is cropping up for me constantly, too (my own project). I am building under Visual C++ 2005 Express.

The only explanations I've come across so far:
1) exception handling needs to be turned on (which it is - /EHsc)
2) structure alignment should be the same (aligning on 4-byte boundaries)
3) calling conventions should be consistent (the default __cdecl is selected for the project)

I get the error at line 105 of event.cpp:

Code: Select all

const wxEventTableEntry wxEvtHandler::sm_eventTableEntries[] =
    { DECLARE_EVENT_TABLE_ENTRY(wxEVT_NULL, 0, 0, (wxObjectEventFunction)NULL, NULL) };

I have cleaned and rebuilt several times. Other libraries I'm linking against are Pthreads (Win32), Intel Performance Primitives and Boost.

Apologies for talking to myself, but I wonder if these apply:
