Windows Deug Env

[xuanranxiaoshi]

Hi everyone, I now want to develop and debug the Taichi project on Windows through Visual Studio 2022. After I built the project using the debug configuration documentation on the Taichi website: https://docs.taichi-lang.cn/docs/windows_debug, a puzzling exception appeared in Step 4.

The project was successfully built at run time without error, but the debugging did not break at the breakpoint, but directly exited.

Is there something wrong with my process of building Taichi? Here's how I built from the source code:

The LLVM Debug build process is as follows:

cmake ..\llvm\ -G "Visual Studio 17 2022" -A x64 -DLLVM_ENABLE_RTTI:BOOL=ON -DBUILD_SHARED_LIBS:BOOL=OFF -DCMAKE_BUILD_TYPE=Debug -DLLVM_TARGETS_TO_BUILD="X86;NVPTX" -DLLVM_ENABLE_ASSERTIONS=ON -Thost=x64 -DLLVM_BUILD_TESTS:BOOL=OFF -DCMAKE_INSTALL_PREFIX=installed -DCMAKE_MSVC_RUNTIME_LIBRARY=MultiThreadedDLL -DCMAKE_CXX_STANDARD=17

git clone --recursive https://github.com/taichi-dev/taichi  
  
cd taichi  
  
$env:TAICHI_CMAKE_ARGS += " -DTI_WITH_VULKAN:BOOL=ON -DTI_WITH_CUDA:BOOL=ON"  

$env:DEBUG = 1 # Uncomment it if you wish to keep debug information.  

$env:TAICHI_USE_MSBUILD = 1
  
python build.py --shell  

# 指定自己生成 LLVM Debug 版本路径后执行

python setup.py develop

Then I open ... /taichi/_skbuild/win-amd64-3.9/cmake-build/taichi. sln, the debugging environment is as follows:

The result is above!

I found a new problem.

After building Taichi in the above way, I execute it directly on the command line:

python tiDemo.py

(tiDemo.py is a simple taichi sample program)

Generate an error:

ImportError: DLL load failed while importing taichi_python: 找不到指定的模块。
Consider installing Microsoft Visual C++ Redistributable: https://aka.ms/vs/16/release/vc_redist.x64.exe

I installed 'vc_redis.x64.exe' but still did not solve the problem.

I'm wondering how compiling Taichi in this way can be imported by a Python program?

[xuanranxiaoshi]

Now I have solved the problem: ImportError: DLL load failed while importing taichi_python: The specified module could not be found.

Instead of compiling Taichi in Debug mode, I set the environment variable to 0;

However, debugging in VS 2022 still reported an error: the python.c source file could not be found.
