使用Visual Studio预览版时含codecvt的代码链接失败求解决方案

Hey there, sorry to hear you're stuck with this linking issue—pre-release Visual Studio builds can be tricky, especially when they throw unexpected bugs like this. Let's walk through some practical steps to get your code linking properly again:

• Roll back to a stable release first
  Preview versions are meant for testing, so they're prone to unaddressed bugs. Uninstall the 15.6.0 Preview 2 build, then grab the latest stable Visual Studio Community edition. This is often the fastest way to resolve preview-specific issues without digging into workarounds.

• Repair your current Preview installation
  If you want to stick with the preview build, try repairing it:

  1. Open the Visual Studio Installer
  2. Find your 15.6.0 Preview 2 instance
  3. Click the three dots (...) next to it and select "Repair"
     This fixes corrupted or missing Visual C++ linker components that might be causing the failure.

• Audit your project's linker configurations
  Sometimes what looks like a compiler bug is actually a misconfigured project:

  • Verify all required .lib files are listed under Linker > Input > Additional Dependencies
  • Check that Linker > General > Additional Library Directories points to the correct paths for your libraries
  • Ensure you're not mixing debug and release builds—linking a debug library to a release target (or vice versa) often causes cryptic linking errors

• Wipe build caches and rebuild from scratch
  Stale build artifacts can cause odd linking issues. Do this:

  1. Go to Build > Clean Solution in Visual Studio
  2. Manually delete the bin and obj folders for every project in your solution
  3. Run a full Rebuild Solution to generate fresh build files

• Report the bug (and check for existing workarounds)
  If none of the above works, this is likely a genuine Visual C++ bug:

  • Open the Visual Studio Feedback Hub via Help > Send Feedback > Report a Problem
  • Search for existing reports matching your error message—other developers might have shared a workaround
  • If no report exists, submit a detailed one with the exact error text, your project setup (target platform, libraries used), and a minimal reproducible sample project. Microsoft typically patches critical bugs in subsequent preview updates.
