What steps will reproduce the problem?
1. Attempt to build python-tesseract from trunk using instructions in wiki on 
Ubuntu 11.10 AMD64

What is the expected output? What do you see instead?

Please provide any additional information below.

If I'm not mistaken "mfcpch.h" is an M$ C++ header file ??? 

What version of the product are you using? On what operating system?

You need to install libtesseract-dev
sudo apt-get install libtesseract-dev libleptonica-dev python-all-dev swig 
libcv-dev

Details please refer to

Hi,

No luck :-( I was in fact missing the OpenCV dependencies which I installed 
(from a PPA which provides v2.3)

someone@somewhere:~/Downloads/tesseract/new/python-tesseract$ sudo apt-get 
install libtesseract-dev libleptonica-dev python-all-dev swig libcv-dev

Any thoughts?

try comment out mfcpch.h in main_dummy.cpp. 
It is not a must in Unix
