How did you check the value of nrPoints?
Make sure that the C/C++, Code Generation, Runtime Library is “/MDd” for both projects. Did you change other project options?
VS 2022 passing std::vector from c++/cli to c++ does not work in debug mode

Hi,
I am trying to pass std::vector from c++/cli to c++. It works in Release mode but in debug mode passed parameter std::vector is always size=0. I am questing is has something to do with c++ settings.
Appreciate any advice

2024-09-04T10:02:09.7733333+00:00 c++/cli code:
reg_impl = new CGS_PCL_reg() //
int nrPoints=source->GetLength(0);
std::vectorstd::vector<double> src;
std::vectorstd::vector<double> tgt;
for (int i = 0; i < nrPoints; i++) { std::vector<double> s; s.push_back(System::Convert::ToDouble(source[i,0])); s.push_back(System::Convert::ToDouble(source[i,1])); s.push_back(System::Convert::ToDouble(source[i,2])); src.push_back(s); std::vector<double> t; t.push_back(System::Convert::ToDouble(target[i,0])); t.push_back(System::Convert::ToDouble(target[i,1])); t.push_back(System::Convert::ToDouble(target[i,2])); tgt.push_back(t); }std::vectorstd::vector<double> value = reg_impl->transformEstimationSVD(src, tgt);
c++ code HEADER:

return finalTransformation;}

2024-09-04T10:56:12.6633333+00:00 This code works fine in Release mode but not in Debug mode. I do not know why.
It worked fine in VS 2015 but not in 2019 and VS 2022 17.10.4 version.

New projects having default options and without Boost seem to work.
