I've done some further searching and found several versions of shell
scripts that are supposed to generate a standalone version of Tesseract.
However, they all fail at the last part of the process, namely building
Tesseract itself! The script builds the libraries for zlib (v1.2.8),
libpng (v1.6.13), libjpeg (9b) and leptonica (v1.73), but fails with the
following error:
checking for leptonica... yes
checking for pixCreate in -llept... no
configure: error: leptonica library missing
I can't find a way to correct this! Here's the config details that lead to
this error:
export CXXFLAGS="-I$BUILD_DIR/include -I$BUILD_DIR/include/libpng16
-I$BUILD_DIR/include/leptonica -lpng -ljpeg -lz"
export CPPFLAGS="-I$BUILD_DIR/include -I$BUILD_DIR/include/libpng16
-I$BUILD_DIR/include/leptonica -lpng -ljpeg -lz"
export LDFLAGS="-L$BUILD_DIR/lib"
export LIBLEPT_HEADERSDIR="$BUILD_DIR/include/leptonica"
./configure --prefix=$TESSERACT_DIR --with-extra-libraries=$BUILD_DIR/lib
[Note: I added the CXXFLAGS as well as the CPPFLAGS as I wasn't sure which
was needed]
I have attached the latest version of the shell script I'm using so you can
see the context.
Can anyone fix my script or tell me another way of generating a standalone
version of Tesseract for the Mac?
Thanks
