PtexReader error: unzip failed, file corrupt

[Ronald Pan]

Hi, 

  When I use ptxview to open the sample ptex files, triangle.ptx, I got an error "PtexReader error: unzip failed, file corrupt".

[Brent Burley]

Do the other samples work?  Does ptxinfo work without error?  What platform are you on?

[Ronald Pan]

I have tried bunny.ptx and triangle.ptx. The error is the same. I am using windows 7 + vc2010. Where is ptxinfo?

Thanks.

I build ptxinfo and run it with the same error.

Do the built-in tests pass?  (in src/tests)

That sounds like a problem with your build of zlib.  That error is reported with zlib's deflate returns something other the Z_OK.  If you want a better clue you might look at the zresult in a debugger.  It presumably would be one of:

#define Z_NEED_DICT     2

#define Z_ERRNO        (-1)

#define Z_STREAM_ERROR (-2)

#define Z_DATA_ERROR   (-3)

#define Z_MEM_ERROR    (-4)

#define Z_BUF_ERROR    (-5)

#define Z_VERSION_ERROR (-6)

Beyond that, I'm not sure how to help you get zlib working.
