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

Latest 0.7 , centos5.8
Please provide any additional information below.
The following line uses the correct directories 
gcc -pthread -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall 
-Wstrict-prototypes -fPIC -I. -I/usr/include/tesseract -I/usr/include/leptonica 
-I/usr/local/include/python2.7 -c main_dummy.cpp -o 
build/temp.linux-x86_64-2.7/main_dummy.o

I hope you can help, i didn't want to send a ticket cause I am guessing it's a 
pretty specific problem but i am going crazy with this setup right now so i 
need some help -and no, changing OS is not an option sadly)

Hi, Free
I just tried your step by step guide for Centos on my EC2 AMI instance, which 
is basically a centos. 
I find many points in your guide not accurate and not executable, and well, in 
the end, I failed to compile python-tesseract :( 

please allow me to make some amendments:
1. use `sudo` before `yum`, `cp` commands
2. for installation of opencv 2.4.2, patch is not working and `sed -i.bak 
's|libdir=|libdir=/usr/lib64|g' unix-install/opencv.pc` does not make sense 
because there is no such file as "unix-install/opencv.pc"
3. in latest tesseract,  ` --with-libdir=lib64` is no longer a valid option for 
`configure`
4. for commands like `cp -Rf *opencv* /usr/lib64`, I don't quite understand, 
why not `ln -sf`? is that a big deal?
5. most importantly for me, I cannot get python-tesseract to build... It gave 
me 
     main_dummy.cpp:22:21: fatal error: tprintf.h: No such file or directory

I checked my /usr/include/tesseract, there is no such file. 

Sorry I am new to all these,  and I cannot solve this problem on my own, could 
you please help me out of this? and maybe fix the doc as well for others? 

Thank you for your great work! Eagerly looking forward to your response.

Hi,

Did vincent get a fix to the EC2 AMI install ?

I too am following instrucitons and I'm getting the same error when running the 
python setup.py

Please help me as I am so close :-)

Hi, 

Solved it after with help of this post:
http://code.google.com/p/python-tesseract/issues/detail?id=20#c14

All i needed to do was
sudo cp ~/tesseract/tesseract-ocr/ccutil/tprintf.h /usr/local/include/tesseract
