INSTALLING gOCR

INSTALLING BINARIES
|
||
|
|
-------------------
|
||
|
|
Be sure that you have all the libraries needed. To install a binary package,
|
||
|
|
do the following:
|
||
|
|
|
||
|
|
1. Unpack the archive if you have not done so already:
|
||
|
|
|
||
|
|
tar -xzf gocr[version].tar.gz
|
||
|
|
|
||
|
|
on older tar versions, the above line might not work. If so, try the following:
|
||
|
|
|
||
|
|
gzip -cd gocr[version].tgz | tar -xf -
|
||
|
|
|
||
|
|
This creates the directory ./gocr[version] containing the source from
|
||
|
|
the main archive.
|
||
|
|
|
||
|
|
2. Change to gocr directory and run make (use GNU Make).
|
||
|
|
|
||
|
|
cd gocr[version]; make install
|
||
|
|
|
||
|
|
That's it.
|
||
|
|
|
||
|
|
INSTALLING FROM SOURCE
|
||
|
|
----------------------
|
||
|
|
|
||
|
|
Requirements
|
||
|
|
------------
|
||
|
|
You'll need a compiler; we recommend gcc, but the code should compile in any
|
||
|
|
good one. gcc is available at http://gcc.gnu.org. I had some problems with gcc
|
||
|
|
2.95.1 (it consumed a LOT of memory while compiling ocr0.c). 2.95.2 seems to
|
||
|
|
be better.
|
||
|
|
|
||
|
|
gOCR provides some simple functions to read/write pnm archives. Though not
|
||
|
|
needed, we strongly suggest, however, that you install the NetPBM package. Its
|
||
|
|
official URL is: http://download.sourceforge.net/netpbm/.
|
||
|
|
|
||
|
|
Installing this package will add support to many different image formats.
|
||
|
|
If you have a NetPBM version older than August 2000, we suggest that you
|
||
|
|
download a more recent one, to take advantage of the new PAM functions.
|
||
|
|
|
||
|
|
To create some of the examples provided, you'll need transfig.
|
||
|
|
This is completely optional.
|
||
|
|
|
||
|
|
Procedure
|
||
|
|
---------
|
||
|
|
1. Unpack the archive if you have not done so already:
|
||
|
|
|
||
|
|
tar -xzf gocr[version].tar.gz
|
||
|
|
|
||
|
|
on older tar versions, the above line might not work. If so, try the following:
|
||
|
|
|
||
|
|
gzip -cd gocr[version].tgz | tar -xf -
|
||
|
|
|
||
|
|
This creates the directory ./gocr[version] containing the source from
|
||
|
|
the main archive.
|
||
|
|
|
||
|
|
2. Change to gocr directory and run configure.
|
||
|
|
|
||
|
|
cd gocr[version]; ./configure
|
||
|
|
|
||
|
|
For a list of options, try ./configure --help.
|
||
|
|
If something goes wrong, try to run autoconf.
|
||
|
|
|
||
|
|
3. Run make (GNU Make). This can take a while.
|
||
|
|
|
||
|
|
make
|
||
|
|
|
||
|
|
4. gOCR comes with some examples, which are generated from xfig-files.
|
||
|
|
If you have transfig installed, you can make them:
|
||
|
|
|
||
|
|
make examples
|
||
|
|
|
||
|
|
5. Install the binaries. You may need to do this as root.
|
||
|
|
|
||
|
|
make install
|
||
|
|
|
||
|
|
6. Run gocr, or the frontend you chose.
|
||
|
|
|
||
|
|
gocr -h Shows help
|
||
|
|
gocr.tcl Runs Tcl GUI
|
