Programmatically updating FILEVERSION in a MFC app w/SVN revision number

Question

How do I go about programmatically updating the FILEVERSION string in an MFC app? I have a build process that I use to generate a header file which contains the SVN rev for a given release. I'm using SvnRev from http://www.compuphase.com/svnrev.htm to update a header file which I use to set the caption bar of my MFC app. Now I want to use this #define for my FILEVERION info.

What's the best way to proceed?

Answer 1

An .rc file can #include header files just like .c files can. I have an auto-generated version.h file, which defines things like:

#define MY_PRODUCT_VERSION    "0.47"
#define MY_PRODUCT_VERSION_NUM 0,47,0,0

Then I just have my .rc file #include "version.h" and use those defines.

VS_VERSION_INFO VERSIONINFO
 FILEVERSION MY_PRODUCT_VERSION_NUM
 PRODUCTVERSION MY_PRODUCT_VERSION_NUM
...
 VALUE "FileVersion", MY_PRODUCT_VERSION "\0"
 VALUE "ProductVersion", MY_PRODUCT_VERSION "\0"
...

I haven't tried this technique with an MFC project. It might be necessary to move your VS_VERSION_INFO resource to your .rc2 file (which won't get edited by Visual Studio).

Don't have enough points to comment yet, but whatever solution you choose keep in mind that FILEVERSION fields can only support a short integer. In our situation, our SVN revision was already above this and resulted in an invalid revision number in our FILEVERSION.
