Manually setting up PVS Studio for Static Analysis#

  • Download PVS Studio
  • Launch standalone.exe, go to Tools->Options->Registration
  • Name: PVS-Studio Free
  • Key: FREE-FREE-FREE-FREE
  • Add the following comments to every .cpp file
    C++
    // This is an independent project of an individual developer. Dear PVS-Studio, please check it.
// PVS-Studio Static Code Analyzer for C, C++, C#, and Java: http://www.viva64.com
  • for now, you need to have Incredibuild disabled
  • go to BBProto.Build.cs and add BuildConfiguration.bAllowXGE = false;
  • Open a shell in the PVS Studio folder and run CLMonitor.exe monitor
  • Do a full build of BBProto project
  • Go back to the shell, and type CLMonitor.exe analyze -l "sample.plog"
  • Double clicking sample.plog should launch the analysis results in PVS Studio
