Xcode's build options include a Current Project Version variable, and I was wondering if there was any way to use that in a C++ program.
std::string version_info = "FooProgram " + /* magic here? */ ;

1And that's how you learned using "autoconf"... =) – Feb 21 '13 at 17:26

@H2CO3 What, you can use `autoconf` with Xcode? – Blacklight Shining Feb 21 '13 at 17:37

I don't know, I don't use Xcode. – Feb 21 '13 at 17:38

@slugonamission I agree, seeing as how that's for Objective-C and iPhone development, and my question deals with C++ and has nothing to do with iPhones. ;) – Blacklight Shining Feb 21 '13 at 18:07

@BlacklightShining - yes, but you can use the concept of the variables they explain to add a build variable (using `-Dfoo=bar`) to your compiler's command line. – slugonamission Feb 21 '13 at 18:08

@slugonamission …and now the question becomes how to make the version string available to _that._ XD – Blacklight Shining Feb 21 '13 at 18:12

I'm not firing up XCode to test this, but use a similar concept to add the variable to GCC's command line. – slugonamission Feb 21 '13 at 18:12

@slugonamission Ahh, okay. Adding a preprocessor macro for `__PROJECT_VERSION__=\"${CURRENT_PROJECT_VERSION}\"` solved this. – Blacklight Shining Feb 21 '13 at 18:34
