MisMatched Tag error

I just updated my version of the source code from CVS to the latest version and ran the compile using MSVC Express 2009. As I try to read a GPX file, I get the following error:

[I:\gpsbabel\msvc\Release]gPSBabel.exe -D1 -vs -i gpx -f c:\apps\gsakout\delorme.gpx -o delbin,nukewpt,logs=1 -F usb:

GPSBabel Version: 1.3.7-beta20090906

options: module/option=value: gpx/snlen="32" (=default)

options: module/option=value: gpx/gpxver="1.0" (=default)

I went back and used the newest beta version of GPSBabel that was on the website and it runs without error. Is there an error that I introduced somewhere or has something been checked in that has broken the parser? I should note that this has been working up to the latest CVS update. Any help would be greatly appreciated.

Thanks.

I'd all but given up building it with MSVC Express. I remember sinking a couple of evenings into trying to unwind the tangle of development kits and manually configured paths just before my HD died (first in 23-ish years), taking out my Vista installation.

If you *really* think it's a time travel problem, you can walk through the tree via "cvs up -D'2 days ago'" and binary search until you find it.   But I don't think we've done anything very interesting to the GPX reader in a long time.

Almost always, on Windows, this is caused by a mismatch in the expat interfaces.   There are two versions of the dll for expat. One tosses bytes across the interface in UTF-8 and the other in UTF-16, the Windows-beloved wide character mode.   It's depressingly easy to get them mixed up and it'll lead to the kind of symptoms you're describing.

Wide
Set include paths to pick up msvc/Expatw/ for expat header
Set lib path to pick up msvc/Expatw/libexpatw.{dll,lib}

Not wide
Same as above, but with "Expat/" instead of "Expatw"

There's a parallel pair for mingw, but if you're on MSVC you don't care.

The thing that can nail you is objects that are built with the "wrong" include. If you build, say, gpx.o with the wide verision then tinker with the includes to link against the narrow version, hilarity ensues.

So to diagnose this, I'd pick a path (honestly, I consider the wide version a distraction) and double chcekc the includes and libs above, vaporize all the objects, and then diagnose from there.   If you were to submit a working MSVC proj/build/whateveritisthisyear file that ignored the wide version, I wouldn't blink an eye at that omission.
