RE: VC++ /Zp1....failure

[Jesse Pelton]

You might try using something like the following in the headers that define structures and/or classes that must have 1-byte alignment:

 

#pragma pack (push, 1)

// structure/class definition

#pragma pack (pop)

 

I may not have the syntax quite right, but it should be close. You'd compile with the default alignment, so all structures except those so bracketed would be 8-byte aligned.

 

Or, if you're brave, you could try recompiling Xerces. The best option would be to convince the project management that 1-byte alignment is crazy when you're dealing with three layers and at least one library from another source.

HI,

 

Thanks for the reply....

The problem is,

Our application has been divided into 3 layers. Presentation,control and the data communication layers.

I am writing the Data comm layer.  I will get the C data structures from the other layers in the zp1 format and

I need to populate the structures after parsing the XML file received from the server.

So, I cant change the alignment to /Zp8 (default).

 

How do I get around with this problem??

 

Please Help

 

Thanks

Gopi

You must use the same structure alignment in your application the pre-compiled Xerces library uses. You could try rebuilding Xerces with the structure alignment you want to use, but I wouldn't recommend it.

The bottom line is you shouldn't be mucking with such an option unless you understand the ramifications.

HI,
 
I have a small cpp file where I will create a parser object as
 
DOMParser    parser  = new DOMParser();
....
,,....
 
 
and call
 
delete parser after that in the same block.
 
I created this in a VC++ Debug Mode. If I set the structure alignment option as /Zp8 ( default ),
everything works fine but when I change to /Zp1, it cribs at the line where i do
delete parser. The error is
 
 DAMAGE: after Normal block(#48) at 0x010c.......
 
 
 
could anyone tell me why this is happening?
 
Your help will be Highly appreciated...
 
Regards and Thanks
gopi
