Qt auto software version?

Question

Does Qt support any version information for your program, such as .NET? What is the build number? Or does this provide an easy way to access SVN revisions?

Answer 1

Not.

But if you use qmake , you can set the compiler flags in the build system based on the results of arbitrary commands, which can be useful for doing what you want.

For example, if you used git, you could do something like this in your .pro file:

 REVISION = $$system(git rev-parse HEAD) DEFINES += APP_REVISION=$$REVISION 

This will give you the APP_REVISION macro when compiling your program, which you can use as follows:

 // stringize macro #define _STR(X) #X #define STR(X) _STR(X) QTextStream(cout) << "MyApp revision " STR(APP_REVISION) << endl;
