What mailing list?

Oke, I like this policy. Good point.

FYI MacOS
I just succeeded to compile both project tesseract-ocr and ocropus with latest svn
2007/04/12
I updated missing packages (aspell) with FINK, and that was done!
my system is

compiling openfst however does not work on my Leopard Mac OS X:

$ make
( cd lib ; make all )
g++ -shared   -o libfst.so fst.o properties.o symbol-table.o compat.o
Undefined symbols:
  "_main", referenced from:
      start in crt1.10.5.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make[1]: *** [libfst.so] Error 1
make: *** [all] Error 2

 On intel Leopard: 
confirming that ocropus and tesseract build.

 Halshura: 
 I have the same issue with OpenFST, am investigating libtool as mentionned here:

http://forums.macrumors.com/showthread.php?t=94571

Adding to previous comment:

 You can indeed build OpenFST by modifying the makefiles. In ./lib/Makefile and ./bin/Makefile, there are 
several lines that have "on OSX" comments.

 E.g. (lib/Makefile)

LIBTYPE=so # "dylib" on macosx
SOFLAGS=-shared  # "-dynamiclib -flat_namespace -undefined suppress" on macosx

 Just make those lines:

LIBTYPE=dylib
SOFLAGS=-dynamiclib -flat_namespace -undefined suppress


 I'm currently building on OSX Leopard (intel). Haven't yet had any errors and it's been churning for 10 
minutes. Have not built ocropus with externals, but I'm pretty sure it will work.

 Aside from the above building issues, there is an error generated in the OpenFST header file when trying to build ocropus. It 
claims there is an ambiguous template expansion. The ambiguous choices are between: colib::swap and 
colib::<unnamed>::swap

 I do not have the error code handy right now, but modifying this following line in statesort.h (in the openFST library) fixes the 
error:

line 64
    for (; !done[s1]; s1 = s2, final1 = final2, swap(arcs1, arcs2)) {

becomes:
    for (; !done[s1]; s1 = s2, final1 = final2, colib::swap(arcs1, arcs2)) {

 I will be notifying the OpenFST project about this.


 Once this is done, the system builds and runs. However it seems most tests are failing when running the smoke tests. 
(Failures are mainly in character recognition (recognized character capitalizations), and only one hard error (crash).

 My compiler version is:

Used this changes :

LIBTYPE=so # "dylib" on macosx
SOFLAGS=-shared  # "-dynamiclib -flat_namespace -undefined suppress" on macosx

 Just make those lines:

LIBTYPE=dylib
SOFLAGS=-dynamiclib -flat_namespace -undefined suppress

and worked for me. thanks

BTW

 i had this problem with a different software...

I compiled it with cygwin under windows. 

what is the code or steps for installing ocropus or tessaract or OCR on the linux
(ununtu system?
hw it works on ununtu?

windows is a stupid OS. so the ocropus have no need to wast time for windows pakege  

Given it compiles on a Mac, why not provide an executable in the downloads section?

has anyone tried building on os x recently? when i try to use scons it tells me i need libtiff4-dev or equivalent. 
fink only has libtiff3.something and installing libtiff4.beta doesnt seem to work either. if i use configure it fails 
because it can't find Makefile.in. i have it working just fine on ubuntu, but i would really like it to run on os x. 
any thoughts, help for os x?

For those interested in a simple droplet interface to OCRopus on Mac OS X, check out

os x:
i don't know how much of this is actually required. i simply tried
to install everything that would be installed on an ubunutu machine
via the recommended install procces. this worked for me:
	o	install os x (10.5.6)
	o	install xcode and dev tools (3.2.1)
	o	install mercurial from source (1.2.1)
		$	sudo python setup.py install
	o	install scons from source (1.2.0)
		$	sudo python setup.py install
	o	install libpng from source (1.2.37)
		$	./configure
		$	make check
		$	sudo make install
	o	install libtool from source (2.2.6)
		$	./configure
		$	sudo make install
	o	install libjpeg from source (6b)
		-copy libtool (the executable) from the directory
		-where you compiled it (.../libtool-2.2.6/) into the
		-root folder of libjpeg (.../jpeg-6b/)
		$	./configure --enable-static --enable-shared
		$	sudo make install
	o	install giflib from source (4.1.6)
		$	./configure

		-download language data packs of your choosing from

		-files
		$	./configure
		$	sudo make install
	o	install leptonica from source (1.61)
		$	./configure
		$	sudo make install
	o	install ffmpeg from source (revision 29349)
		-i did not need to install svn, but your
		-system may not have had it preinstalled
		-this one takes a while to build
		$	svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg
		$	./configure
		$	sudo make install
	o	install gsl from source (1.9)
		-this one takes a while to build
		$	./configure
		$	sudo make install
		
now the fun begins

	o	install iulib from source
		$	hg clone http://mercurial.iupr.org/iulib

		-to:

		-3 in my install of osx my /usr/bin/ folder contained g++-4.0, g++-4.2
		-and g++ which was a soft link to g++-4.0 in order to use the -fopenmp
		-(specified on lines 150 and 151) i had to delete old soft link 
		-(sudo rm /usr/bin/g++) and replace it with a link to g++-4.2
		-(sudo ln -s /usr/bin/g++-4.2 /usr/bin/g++)
		-4 add a line containing:
		#include <liblept/environ.h>
		-to .../ocropus/ocr-utils/compoenents.h
		-i added it on line 28 but anywhere sensible is fine
		-5 add a line containing
		#include "../ocr-utils/queue.h"
		-to .../ocropus/ocr-line/glcuts.cc
		-i added it on line 38 but anywhere sensible is fine
		-6 add a line containing
		#include "../ocr-utils/queue.h"

		-10 finally and this is VERY important. it will not effect
		-whether or not your ocropus builds but it will effect whether
		-or not it works: delete the -O3 in the qutoes on on the opt
		-line... i.e. change line 67
		-from:
		opts.Add('opt', 'Compiler flags for optimization/debugging', "-O3")
		to:
		opts.Add('opt', 'Compiler flags for optimization/debugging', "")
		-i do not know why have the optimization in there is a problem
		-if i leave it in i get:
		terminate called after throwing an instance of 'char*'
		Abort trap

		$	sudo scons install

In addition to the above changes, I needed to do the following to get Ocropus0.4 working on OSX10.5.

-----< 1 >------
If using scons 1.2 comment out line 120:
replace 
env.Append(LIBS=["tiff","jpeg","png","gif"])
width
#env.Append(LIBS=["tiff","jpeg","png","gif"])

-----< 2 >------
Replace lines 102 and 103 with:
env.Append(LIBPATH=["${iulib}/lib", "/usr/local/lib", "/usr/lib"])
env.Append(CPPPATH=["${iulib}/include", "/usr/local/include", "/usr/include/"])

-----< 3 >------
Change line 94 of /usr/local/include/colib/rowarrays.h from 
        return (T)sqrt(rowdist_euclidean_squared(values,i,v));
to 
        return (T)sqrt((float)rowdist_euclidean_squared(values,i,v));
