About this tag
The msvc tag on WindowsForum.com covers Microsoft Visual C++ compiler toolchain issues, particularly the cl.exe command-line compiler. A recurring theme is the "cl is not recognized" error that appears when developers install Visual Studio Build Tools but run cl from an ordinary Command Prompt or PowerShell window. The content explains that MSVC requires more than just the location of cl.exe; the shell must also have paths to headers, libraries, the linker, and supporting tools, which the Developer Command Prompt configures automatically. This tag is useful for Windows developers troubleshooting C++ build environments on Windows 10 and Windows 11.
