Правильный способ встраивать и объединить питон в C ++, чтобы избежать кодировки "modulenotfounderror"? ⇐ C++

[Anonymous]

Я пытаюсь внедрить Python в мой C ++ Dll.
Идея состоит в том, что DLL, после распределенного, должен быть достаточным и не полагаться на другие установки и загрузки. /> Как я могу сделать мой DLL, чтобы не быть рядом с VCPKG_INSTALLED < /code>?

Код: Выделить всё

void assertPyInit() {
if (!Py_IsInitialized()) {
PyConfig config;
PyConfig_InitPythonConfig(&config);

// Get the executable path instead of current working directory
wchar_t exePath[MAX_PATH];
GetModuleFileNameW(NULL, exePath, MAX_PATH);

// Remove the executable name to get the directory
std::wstring exeDir = exePath;
size_t lastSlash = exeDir.find_last_of(L"\\");
if (lastSlash != std::wstring::npos) {
exeDir = exeDir.substr(0, lastSlash);
}

// Now build Python path relative to executable location
std::wstring pythonHome = exeDir + L"\\..\\..\\vcpkg_installed\\x64-windows-static-md\\x64-windows-static-md\\tools\\python3";

// Resolve the full path to eliminate ..  references
wchar_t resolvedPath[MAX_PATH];
GetFullPathNameW(pythonHome.c_str(), MAX_PATH, resolvedPath, NULL);
pythonHome = resolvedPath;

std::wstring pythonLib = pythonHome + L"\\Lib";
std::wstring pythonSitePackages = pythonLib + L"\\site-packages";
std::wstring pythonDLLs = pythonHome + L"\\DLLs";

// Set the Python home directory
PyConfig_SetString(&config, &config.home, pythonHome.c_str());

// Set the module search paths
std::wstring pythonPathEnv = pythonLib + L";" + pythonSitePackages + L";" + pythonDLLs;
PyConfig_SetString(&config, &config.pythonpath_env, pythonPathEnv.c_str());

PyStatus status = Py_InitializeFromConfig(&config);
PyConfig_Clear(&config);

if (PyStatus_Exception(status)) {
PyErr_Print();
return;
}

PyRun_SimpleString("sys.path.append(\".\")");
