Version Numbers in a project with Qt

Question

Version numbers are needed all over a project; in installers, code, toolchains etc. I despise duplication. I want my version numbers to be stored in one central authoritativ

Answer 1

I use something like this in my build system

#.pro file
#Application version
VERSION_MAJOR = 1
VERSION_MINOR = 0
VERSION_BUILD = 0

DEFINES += "VERSION_MAJOR=$$VERSION_MAJOR"\
       "VERSION_MINOR=$$VERSION_MINOR"\
       "VERSION_BUILD=$$VERSION_BUILD"

#Target version
VERSION = $${VERSION_MAJOR}.$${VERSION_MINOR}.$${VERSION_BUILD}

And after that you can use VERSION_MAJOR and others as normal macro in your application.
