configure: error: leptonica library missing -- FAQ is not working

[Dennis Park]

faq says:

      CPPFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib" ./configure

would work, but i still got the problem:

    ......

    checking for mbstate_t... yes

    checking for leptonica... yes

    checking for pixCreate in -llept... no

    configure: error: leptonica library missing

my leptonica header files are present in /usr/local/include/leptonica and .so files(like liblept.so.5.0.0) present it /usr/local/lib

I'm using tesseract-3.04.

Does anyone has any clue?

Thanks in advance.

Dennis.

have a look at config.log for reason (search for "pixCreate")

1689:configure:17009: checking for pixCreate in -llept

1742:| char pixCreate ();

1746:| return pixCreate ();

1812:ac_cv_lib_lept_pixCreate=no

any clue?

Thanks

That lines are just summary of test above that lines:

configure:16988: checking for leptonica

configure:17007: result: yes

configure:17009: checking for pixCreate in -llept

configure:17034: g++ -o conftest -g -O2 -I/home/work/.jumbo/include -I/home/work/.jumbo/include/leptonica -L/home/work/.jumbo/lib conftest.cpp -llept  -lpthread  >&5

/home/work/.jumbo/lib/liblept.so: undefined reference to `TIFFCleanup'

collect2: ld returned 1 exit status

E.g. your leptonica build is wrong. You are not able to use that leptonica library for anything.

Elso you mentioned  you are using CPPFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib", but g++ is claiming something else:

configure:2709: g++  -I/home/work/.jumbo/include -L/home/work/.jumbo/lib conftest.cpp

Thanks, Zdenko

./configure is ok now.

Have to install leptlib following instruction: http://www.leptonica.com/vs2008doc/building-image-libraries.html

Thanks, again
