Re: unsigned short const x const link errors in VS NET 2003

Hi Charles,

Alberto,
I was curious as to why the MS projects for 
Xerces do not specify that option (wchar_t as 
native type.)  I had noticed it while I was 
working on building Xerces on windows with MingW-MSYS.

The problem is that the setting must be the same 
of the main application, and there have been no 
feedback from the users about what they use. On 
the other end, VC8 projects do have it.

thanks,

Hi Matthias,
you should check that the option 'Treat wchar_t 
as built-in type' (found in the project 
properties -> C/C++ -> Language) has the same 
value for both the XercesLib project and the 
project of the executable that uses Xerces.
Also, your project should list the Xerecs 
library in the Linker section (xerces-c_2.lib 
for Release builds, xerces-c_2D.lib for debug builds)
Hope this helps,
Alberto

Hi!

At first, I'm from Germany. Please be gentle 
if my English is not as good as yours. ;)

This is the situation I'm in right now:
Building the Xerces (-all) project for my 
Visual Studio .NET 2003 IDE (7.1) was successful.
In Extras -> Options -> Projects I set the VC++ folders for:
- executables (the Debug folder - where the DLL is)
- includes (the xerces-c-src_2_7_0\src folder)
- references or links (AGAIN the Debug folder - where the LIB is)
- libraries (AGAIN the Debug folder - where the LIB is)
- sources (AGAIN the xerces-c-src_2_7_0\src folder)
I hope that these folder setting are correct.
The Xerces build instructions don't mention 
all of these settings and where they can be found in VS. :(

Then I went on and wrote some code but got 
some Xerces-related errors during compiling my stuff.

I remembered that there were some example 
projects, so I tried to compile one that's called SAX2Count.
And here's the most recent (German) error listing:

END LISTING.

I read a lot of threads but none seems to fit to my problem.
There is a thread with a quite similar error 
listing and the reason was that headers were 
compiled as a consequence of a wrong value
in the registry. Unfortunately, that's not the 
solution to my problem. At least that's what my registry settings say...

To me, it looks as if there's something with "unsigned short const * const".
What shall I do to avoid these errors and warnings?
Please answer as detailed as you can because 
I'm new to C++, Visual Studio, and Xerces.

Thank you.
