Hi list,
at least starting Mapserver 4.10 (GDAL 1.3.2) there seems to be a
problem with reading empty MapInfo TAB files, whereas in the past
(4.6 for sure) this used to work. Is this issue known to someone?
The error I get is:
09-Jul-2008 18:08:23] PHP Warning: [MapServer Error]:
msOGRFileNextShape(): InitBlockFromData(): Invalid Block Type: got 0
expected 2
in D:\ms4w\apps\stragisweb\htdocs\common\chameleon\htdocs\common
\wrapper\drawmap.php on line 533
An example TAB file can be found here:

Best regards,

Bart,
I tried your test TAB with ms4w 2.2.7 (GDAL 1.5.0 and Mapserver 5.0.2)
and: 1) ogrinfo reads the tab normally, 2) shp2img created the blank
map image properly with no errors, and 3) I modified /ms4w/Apache/
htdocs/quickmap.php to point to this test mapfile and it also
correctly produced a blank map image in the browser.
The key points in my test mapfile are:
...
