Hi,
i never tried to give tesseract a pdf as an input.
cygwin has leptonica 1.71 or 1.72 by default so i used this for compiling.
maybe leptonica doesn't like pdf files so it might complain.
so ShreeDevi Kumar might convert the pdf into an image or he uses a
normal image (tif, jpg, etc.).
greetings,
simon

It looks like leptonica issue. Did you try to build and run leptonica
progs (all that has pdf in name)?
