Recently we upgraded from Visual Studio 2003 to Visual Studio 2008 for our Windows products and I've been having one heckuva time trying to build. I keep getting the following error...
fatal error C1090: PDB API call failed, error code '23' : '(
One interesting hit on Google produces this, a bug report marked as By Design. If you look in the comments for the report you'll see two comments saying it's still around. Why, yes, yes it is, and I'm experiencing it.
Hopefully I'll be able to find a workaround, or a fix for it, and soon. It's strange it's only happening for this one particular codebase, I've been building other things with Visual Studio 2008 for a while now, without issue.
Time to dig around a bit.
