Scott Morgan commented on XERCESC-2137:
---------------------------------------
Yes, MFC apps in Debug mode throw build errors without the XERCES_MFC_SUPPORT
items.
Basic steps to reproduce:
# In Visual Studio, create an MFC app
# Open up the app's main .cpp file (same as project name)
# include <xercesc/util/XMLString.hpp>
# In app's InitInstance function add in
{code:java}
XMLCh tempStr[100];
XERCES_CPP_NAMESPACE::XMLString::transcode("abc", tempStr, 99){code}
# Compile file in debug mode. You get a load of errors that tie back to
operator new use. Release mode is okay.
Doesn't seem to hit plain win32 apps.

> Issue Type: Bug
> Components: Build

> Reporter: Scott Morgan

> Attachments: mfc_debug_cmake.patch

>
> The XERCES_MFC_SUPPORT define is needed for Visual Studio debug builds, it
> activates some code in XMemory.hpp/cpp
> Should just be a case of detecting MSVC in the main CMakeLists.txt and adding
> a '#cmakedefine XERCES_MFC_SUPPORT' line in
> Xerces_autoconf_config.hpp.cmake.in
