Comment #18 on issue 1 by jtraviswebb: OCRopus only works on Ubuntu or

http://code.google.com/p/ocropus/issues/detail?id=1
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?

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
$ sudo make install
o install libtiff from source (4.0.0.beta3)
-safari does not seem to be able to open the ftp site
-to download the file, but firfox works just fine
$ ./configure
$ sudo make install
o install SDL from source (1.2.13)
$ ./configure
$ sudo make install
o install SDL_image from source (1.2.7)
$ ./configure
$ sudo make install
o install SDL_gfx from source (2.0.19)
$ ./configure
$ sudo make install
o install ImageMagick from source (6.5.3-2)
-again my safari does not like their ftp
-but firefox works fine
-this one takes a while to build
$ ./configure
$ sudo make install
o install tesseract from source (2.03)
-download language data packs of your choosing from
-the tesseract website (i picked english) and dump
-the contents into the .../tesseract-2.03/tessdata
-folder. i should ask you if you want to replace some
-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
-change line 63 of SConstruct in the root folder (.../iulib/)
-from:
if not conf.CheckLibWithHeader('tiff', 'tiff.h', 'C', 'inflate();', 1):
-to:
if not conf.CheckLibWithHeader('tiff', 'tiff.h', 'C', 'autoadd=1):
$ scons
$ sudo scons install
o install ocropus from source
$ hg clone http://mercurial.iupr.org/ocropus
-1 change line 115 of SConstruct in the root folder (.../ocropus/)
-from:
assert conf.CheckLibWithHeader('SDL', 'SDL/SDL.h', 'C')
to:
assert conf.CheckLib('SDL')
-2 change line 116 of SConstruct in the root folder (.../ocropus/)
-from:
assert conf.CheckLibWithHeader('SDL_gfx', 'SDL/SDL_gfxPrimitives.h', 'C')
-to:
assert conf.CheckLib('SDL_gfx')
-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"
-to .../ocropus/ocr-linedeg/seg-cuts.cc
-i added it on line 37 but anywhere sensible is fine
-7 add a line containing
extern char** environ;
-to .../ocropus/ocr-utils/components.cc
-i added it on line 32 but anywhere sensible is fine
-8 in .../ocropus/ocr-voronoi/read_image.cc change line 105
-from:
TIFFHeader hdr;
-to:
TIFFHeaderClassic hdr;
-9 in .../ocropus/ocr-voronoi/read_image.cc change line 122
-from:
if(hdr.tiff_version != TIFF_VERSION &&
-to:
if(hdr.tiff_version != TIFF_VERSION_CLASSIC &&
-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
$ scons
$ sudo scons install
