I have a number of private libraries and headers in a folder that I add to the search folders in POIDE under
tools->options->folders. (the 20 or so headers and libs are in the same folder)
When I first installed the rc4 version the various functions that rely on sysdefs.tag worked just fine.
However when I added these new folders (see attached image) and rebuilt the file nothing worked.
For example: Right click then goto definition pops up a message box saying it can't find whatever header.
I took a look at the sysdefs.tag file in a hex editor and it does have the correct paths to all the files... but no drive letters.
If I remove the extra folder(s) then rebuild the file, it will work again... but not for my libraries.
This appears to be a bug in the way sysdefs.tag is built. Without my extra folders it uses paths relative to the PellesC installation folder. With my extras it (correctly) attempts to use absolute paths but omits the drive letter.
