I've been looking for documentation on how to run the ocropus-0.2
tests,
but so far have been unable to find any. Consequently, I've
documented my
installation instructions and my experiences running these tests
below.
These instructions show how to install ocropus-0.2 and
the necessary software to run the ocropus-0.2
test programs. I was able to run ./run-tests after fixing a bug
and removing some tests that were prepended with the comment
"# fix the following scripts", but was unable to run the big-tests
completely
without error.
Are these errors in big-tests known, or is it an installation problem
on my
side?
Thanks,

chmod -R ugo+r tessdata
exit
cd
cd tesseract-2.03

For OpenFST library ...
svn checkout http://ocropus.googlecode.com/svn/external ocropus-
external
cd ocropus-external/fst-ocropus/fst

Run tests after installing.
cd ocropus-0.2
cd ocroscript
There is a bug in ./run-tests. Add "cd .." before "./run-toplevels".
export OCROPUS_DATA=/home/guest/ocropus-0.2/data
vi run-toplevels
Then comment out the scripts under
# fix the following scripts
./run-tests
All tests should succeed.
./run-bigtests
Currently some of these tests fail for me.
