3 Installing OCRopus

Following the instructions listed here: http://sites.google.com/site/ocropus/install-0-3

./configure --without-fst --without-leptonica
make
sudo make install

• Note: running configure with the --without-SDL – OKran make – ERROR flag will cause an error during the make process:

/home/leviticus/ocropus/iulib/utils/dgraphics.cc:154: undefined reference to `SDL_FillRect'
/home/leviticus/ocropus/iulib/utils/dgraphics.cc:155: undefined reference to `SDL_UpdateRect'
/home/leviticus/ocropus/iulib/utils/dgraphics.cc:157: undefined reference to `SDL_UpdateRect'
collect2: ld returned 1 exit status
make[1]: *** [ocroscript] Error 1
make[1]: Leaving directory `/home/leviticus/ocropus/ocropus-0.3/ocroscript'
make: *** [all-recursive] Error 1

• re-ran ./configure --without-fst --without-leptonica (configure with SDL) – OK
• ran make – OK
• ran sudo make install (NOTE: OCRopus instructions only tell you to run make install) – OK

Therefore, make sure to not use the --without-SDL flag.
