i'm a chinese, the problem between release version and debug

[opoppopopp]

first sorry for my english...
i set up my own project follow the tutorial, try to compile the 'SkyPlane'.
i create my own directory,put the 'SkyPlane.h' and 'SkyPlane.cpp' in it,
setting the VC6 in order to let VC6 can find the 'ExampleApplication.h' and .cpp. Add the ogremain_d.lib into the link..(that is in the debug mode. in the release,you know,i add the ogremain.lib)

then i compile and link, OK.no problem.

but when i try to 'Debug' it (press F5 in VC6) it report some error.
i excute it in the sample/common/..../. it crash.

BUT I REALLY PASS the COMPILE and LINK!
The RELEASE virsion is OK !! why?

this is some of the VC6's error message:

thank you thank you...
sorry for my english... again

Have you used your debugger to step through the code and find out where exactly it crashes?

Deleting intermediate files and output files for project 'MYOGRE - Win32 Debug'.

then i F5 began to debug run..
and:

You need to at least get a proper stack trace, set breakpoints and step through the code to find out which actual source code line it's failing on, and what the values of the variables at that point are.

That little snippet of assembler could mean anything!

Also, check the Ogre log for any errors.

That access violation error is almost certainly a stray pointer problem, but without knowing more about the code that's causing it, it's impossible to say.

[opoppopopp]

you mean this : ??

// We don't want to assert with random failures, because we want the application to deal with them.

#ifndef RANDOM_FAILURE
// If you hit this assert, then the requested allocation simply failed
// (you're out of memory.) Interrogate the variable 'au' or the stack
// frame to see what you were trying to do.
m_assert( au->actualAddress != NULL );
#endif

if( au->actualAddress == NULL)
{
throw "Request for allocation failed. Out of memory.";
}

and:

Possibly, the key bit there is that the way forward is to do exactly what it says in the comments in the code you posted;

Code: Select all

// If you hit this assert, then the requested allocation simply failed
// (you're out of memory.) Interrogate the variable 'au' or the stack
// frame to see what you were trying to do.

i.e. find out how much memory you're trying to allocate, and which bit of your code called this allocation routine.

A full stack trace would still be handy, as would the line of your code that's causing the problem.

Add _STLP_DEBUG to the projects settings.
