Mismatch '_ITERATOR_DEBUG_LEVEL'

[goodle06]

Have a bunch mkl related linker errors when compiling NeoMathEngine. Could someone help me and tell what is this all about, since I can't look inside mkl dll? Neo ML was build with FineObjects option turned off (if it makes any difference).

@goodle06, Hello, next steps helped me:

1. Install MKL 2018 Update4, what written in Sources.txt
2. Install VS 2015, MKL 2018 doesn't support VS2019, only 2013, 2015, 2017
3. Configure project in CMAKE as "Visual Studio 14 2015", architecture is win32, additional parameter is -DCMAKE_PREFIX_PATH=/path/to/protobuf
4. Generate projects (if u are using cmake GUI)
5. Open project in VS 2015 ONLY(!), build that as Release (!)
   after these steps i got NeoML.dll, NeoMathEngine.dll и NeoOnnx.dll.

I don't know why official instruction is so bad, i hope it will be fixed soon....

@Columbiysky, hello! Thanks for help, I changed to MKL 2018U4 and VS2017 and it got me past those errors, but no I encountered new ones:

K:\NeoML\build\NeoOnnx\src\onnx.pb.h(12): fatal error C1189: #error:  This file was generated by a newer version of protoc which is (компилируется исходный файл K:\NeoML\src\NeoOnnx\src\Nodes\ReluNode.cpp) [K:\NeoML\build\NeoOnnx\src\Ne
oOnnx.vcxproj]

There are plenty of them, but all state the same - some problem with protoc version and I don't know what to do.
Btw, I'm building via cmd\cmake if it matters.

It might be useful to someone, here is actual commands:

cmake -G "Visual Studio 15 2017" -A x64 K:\NeoML\src\NeoML -DCMAKE_INSTALL_PREFIX=K:\NeoML\build64 -DCMAKE_PREFIX_PATH=C:\Users\vcpkg\installed\x64-windows

cmake --build . --target install --config Debug

prefix_path points to protobuf.

@goodle06 Это из-за того что protobuf установлен через vcpkg, удалите его, и пересоберите по этой инструкции:
https://github.com/protocolbuffers/protobuf/blob/master/cmake/README.md
после всего в папке, где вы делали git clone появится папка install (я компилировал только release), -DCMAKE_PREFIX_PATH должен указывать внутрь папки install.

@Columbiysky Спасибо большое! Оказалось, что проблема не с vcpkg, а с моими кривыми руками. Я поставил два protobuf'а, один через vcpkg, один вручную. Второй указал в path, а первый - при билде. Снес оба, снова поставил через vcpkg, все собралось. Еще не тестировал, но по крайней мере скомпилировалось, получил заветные dll'ки.

Итоговая конфигурация:
CUDA 11
Visual Studio 2017
MKL 2018 update 4
