[CMake] VS2010 tries to compile a file with *.res extension when its copied

Fri Jan 21 11:49:50 EST 2011

Ah, I new that would come up. Yeah, they could be renamed. There are only 
a dozen or so of them.

I was just trying to migrate the build system to VS2010 in between 
projects here at work, and this is the only thing holding me back from a 
smooth transition. Changing the extension is certainly an option, but it 
wasn't my first. Sense this is working good in VS2008, I was hoping it was 
just a simple bug, or maybe something I was doing wrong with the 
ADD_CUSTOM_COMMAND.

Do you think this is the way its supposed to work with VS2010? Should I 
make the extension change or work with CMake more?

I don't think it's stupid. No judgment here. :-)

But can it be renamed, or does this logging library require ".res" as the 
file extension?

Well, you're probably going to think this is stupid, but the *.res file is
not actually a resource file in the Microsoft sense of it. It's just a
text file that happens to have the *.res extension. It's a string
localization text file that our logging library knows how to read. It
think it is just happen stance that the logging library expects the files
to end in *.res.

This is similar in nature to
http://public.kitware.com/Bug/view.php?id=11147 and friends...

The fix for that issue is ending up being "obj" file specific, though,
because we have a special handler in place for files with "obj"
extensions. Perhaps we need similar handling for "res" files. (They are
really just obj files from the rc compiler...)

Do you not have the rc file? Or are you compiling it as a custom command
to avoid some other issue with rc files?

This sounds like we need to add a test similar to our existing ExternalOBJ
test, but with a pre-built res file.

Thanks for the discussion -- seems like something needs to be fixed here.
Let's track it down.

On a side note, VS2010 is not trying to compile the *.res file as part of
the executable, because it is marked HEADER_FILE_ONLY, and in addition I
can remove it entirely from the project. Instead, even when the *.res file
appears no where in the solution explorer in VS2010 (except as a
*.res.rule file), VS2010 is still trying to compile it. If I remove the
*.res.rule file it stops trying to compile it. So basically its just
something to do with the ADD_CUSTOM_COMMAND that copies the file.
