From where I sit, the answer I got, addresses a different issue.
If it does address my question & I misunderstood, then please add the necessary details.
I am familiar enough with MSVC to be able to create sentinel files, and the answer does not address the original question: How to give 32& 64-bit versions the same version #
What it seems I need, and something I have no idea how to do, would be have a sub-project which as part of any one of the available steps, gets MSVC to
- create a new version number
- ask MSVC to compile and link both release versions (32 & 64-bit) of the main project
- possibly compile the help file
- possibly initiate producing an installer
steps 2 is the one where I am stuck.
One option I have considered, would be to find a way to invoke MSVC from the command line from another script.
But, if I have to go that far, I might as well consider some version of a CMake project for that part of my problem and only use MSVC for debugging.
