I want to know if MeshLib can be used in VS2022 C++ debug mode.

[Gihong-Yim]

"In release mode, there is no error when calling push_back in the following code:

Triangulation indexList = temp.topology.getTriangulation();
for (int i = 0; i < pstMeshInArchive->uiNumPrimitives; i++)
{
indexList.push_back(ThreeVertIds{ VertId(uiIndices[i * 3 + 0]), VertId(uiIndices[i * 3 + 1]), VertId(uiIndices[i * 3 + 2]) });
}

But in debug mode, an error occurs. when i = 0;

Could it be that I have misconfigured the Debug mode? Is there anything specific I need to do to use Debug mode?"

Hello!

Could you please provide more information about the error, or provide small reproducible example so we could investigate it ourselves.

Can I run debug mode while keeping _ITERATOR_DEBUG_LEVEL=2? I want to know if debugging is possible with this setting.
in my case, includes libraries that require _ITERATOR_DEBUG_LEVEL=2 in debug mode.

By default MeshLib is built with _ITERATOR_DEBUG_LEVEL=0 even in Debug configuration. It is done for performance reasons: Microsoft STL becomes terribly slow in _ITERATOR_DEBUG_LEVEL=2 mode.

If you still want to set _ITERATOR_DEBUG_LEVEL=2, then please

1. Rebuild all vcpkg dependent packages with this setting in x64-windows-meshlib.cmake triplet.
2. Update MeshLib/source/common.props or define CustomMRProps.props in directory above common.props. Please define both _ITERATOR_DEBUG_LEVEL=2 and MR_ITERATOR_DEBUG_LEVEL=2 there. And rebuild MeshLib after it.

Thank you very much for your help
I I tried the method you suggested, but I am still encountering the Link error. Do you happen to know any way to resolve this?

my x64-windows-meshlib.cmake
changed like this

set(VCPKG_CXX_FLAGS_DEBUG "${VCPKG_CXX_FLAGS_DEBUG} /D_ITERATOR_DEBUG_LEVEL=2")
set(VCPKG_C_FLAGS_DEBUG "${VCPKG_C_FLAGS_DEBUG} /D_ITERATOR_DEBUG_LEVEL=2")

commpon.props

<ClCompile>
  <PreprocessorDefinitions>
      _ITERATOR_DEBUG_LEVEL=2;MR_ITERATOR_DEBUG_LEVEL=2;%(PreprocessorDefinitions)
  </PreprocessorDefinitions>
</ClCompile>

then I got link error

Is it the first error in the log? We need to known the very first error.

Could you please translate the error message in English please, or attach the log as text?
