I am running on a redhat system where I do no have admin priviledges or
priviledges to write to /usr/local. Instead, I have recreated the /usr
directory structure under /foo/bar/usr where /foo/bar is a directory i have
full rwx priviledges. I had to build and install from source python 2.7.3 and
swig 2.0.8 to the /foo/bar/usr. Then I repeated these steps for tesseract and
its dependencies. Then after getting python-tesseract to build and install, I
can't successfully import the tesseract module. The output I get is:
The output I get is as follows:
>>> import tesseract
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "tesseract.py", line 26, in <module>
_tesseract = swig_import_helper()
File "tesseract.py", line 18, in swig_import_helper
import _tesseract
ImportError: libtesseract.so.3: cannot open shared object file: No such file or
directory
Here are the steps I followed:
1. mkdir /foo/bar/usr/local
2. set environment variables with
export CFLAGS=-I/foo/bar/usr/local/include; export
LDFLAGS=-L/foo/bar/usr/local/lib; export
LIBLEPT_HEADERSDIR=/foo/bar/usr/local/include
3. Compile and install jpeg-8d, giflib-4.1.6, libpng-1.5.13, tiff-4.0.0,
zlib-1.2.7, and leptonica-1.69 using this command for each library:
./configure --prefix=/foo/bar/usr/local; make; make install;
4. install python 2.7.3 from source to /foo/bar/usr/local:
./configure --prefix=/foo/bar/usr/local; make; make install;
5. grab tesseract-ocr-read-only from svn compile and install:
./configure --prefix=/foo/bar/usr/local; make; make install;
6. copy tesseract-ocr-read-only/ccutil/tprintf.h to /foo/bar/usr/local/include
7. svn checkout http://python-tesseract.googlecode.com/svn/trunk
python-tesseract
8. cd python-tesseract
9. modify lines 99 & 100:
incls = ['/usr/include', '/usr/local/include', '/foo/bar/usr/local/include']
libs=['/usr/lib', '/usr/local/lib', '/foo/bar/user-supported/usr/local/lib']
10. build and install python-tesseract running:
python config.py;
python setup.py clean;
python setup.py build;
python setup.py install --prefix=/foo/bar/usr/local
11. Enter python prompt and import tesseract.
The output I get is as follows:
>>> import tesseract
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "tesseract.py", line 26, in <module>
_tesseract = swig_import_helper()

then u need to manually copy all the .so into a single directory. I guess it
will work

I'm trying to figure out from where the module is attempting to load the
libtesseract.so.3 module. It is already in my /foo/bar/usr/local/lib and
permissions are set to 777 just in case.

I solved the problem. I had to modify the PYTHONPATH to include the custom bin
directory /foo/bar/usr/local/bin

Interesting....
How about install python-tesseract to user-directory?
python setup.py install --user
Of course, I haven't tried it before

I apologize, I added my lib directory not my bin directory. so my PYTHONPATH =
/foo/bar/usr/local/lib which is where libtesseract.so is located.
I attempted to install to user-directory but it does not change anything
related to the location of libtesseract.so. If I had compiled tesseract and
all its dependencies to my user directory, then this may work, but I suspect, I
would still have to add the user directory containing libtesseract.so to my
pythonpath

If it is not too much a trouble, please share your successful story (step by
step preferably) on installing python-tesseract even without an admin right.

a user install would work, but in my particular situation, my user drive does
not have much space. I am close to finishing my write up on what I did. I had
to confirm my steps as I did this spread out over several months. I will post
soon

Better late than never... I think these are still incomplete, but I no longer
have the time to fully retest my instructions
In order to setup python-tesseract to a custom prefix, I had to setup a
completely fresh build environment in a directory where I have permissions.
Additionally I wanted OpenCV support as well, so I had to build OpenCV as well.
I will include the steps I followed for each of these separately. Assuming
the directory you have full rights is at /foo/bar. I chose to install
tesseract and all dependent libraries to /foo/bar/usr/local. I had to build
gcc4.4.7 from source as well because my gcc was producing errors with the
current version of OpenCV 2.4.3.
Building GCC 4.4.7:
mkdir /foo/bar/sandbox;
cd /foo/bar/sandbox;
svn co svn://gcc.gnu.org/svn/gcc/tags/gcc_4_4_7_release gcc;
cd /foo/bar/sandbox/gcc;
wget ftp://ftp.gnu.org/gnu/gmp/gmp-4.3.2.tar.gz
wget http://www.mpfr.org/mpfr-2.4.2/mpfr-2.4.2.tar.gz
wget http://www.multiprecision.org/mpc/download/mpc-0.8.1.tar.gz
tar -xzf gmp-4.3.2.tar.gz
mv gmp-4.3.2 gmp
tar -xzf mpfr-2.4.2.tar.gz
mv mpfr-2.4.2 mpfr
tar -xzf mpc-0.8.1.tar.gz
mv mpc-0.8.1 mpc
mkdir /foo/bar/sandbox/gcc-build;
cd /foo/bar/sandbox/gcc-build;
/foo/bar/sandbox/gcc/configure --prefix=/foo/bar/usr \
--with-local-prefix=/foo/bar/usr/local
make;
make install;
Building OpenCV 2.4.3:
cd /foo/bar/sandbox;
wget

.3.tar.bz2/download;
tar -xjf OpenCV-2.4.3.tar.bz2
