Compiler Error C2220

  • Article

warning treated as error - no object file generated

/WX tells the compiler to treat all warnings as errors. Because an error occurred, no object or executable file was generated.

This error only appears when the /WX flag is set and a warning occurs during compilation. To fix this error, you must eliminate every warning in your project.

To fix, use one of the following techniques

  • Fix the problems that cause warnings in your project.

  • Compile at a lower warning level—for example, use /W3 instead of /W4.

  • Use a warning pragma to disable or suppress a specific warning.

  • Don't use /WX to compile.
