Adding a Subversion version string in binary

Introduction

How to add a version string from Subversion in the executable?

Discussion

Possible solution

Use the Subversion program svnversion.exe to produce version strings.

• Set a pre-build action to call an appropriate script.
• Create a script creating a C source file with a version string.
• Include the created C source in your project.
• Do not include the created C source in your version archive.
• Optionally, use the version string in your code.
  • If so, suggest to create and use a headerfile as done in the example code.
• Optionally, add a post-build action to remove the created C source.
