configure : error: leptonica library missing

[GoogleCodeExporter]

What steps will reproduce the problem?
1.installed leptonica 1.68 according to the instructions, received no errors
2../autogen.sh
3../configure

What is the expected output? What do you see instead?
See attached file.  Problem is at end of configure, there is an error:  
leptonica library missing.

What version of the product are you using? On what operating system?
tesseract-3.01 on linux mint 11.

Please provide any additional information below.
I first installed leptonica from the software source for Ubuntu.  When I got 
the initial error (the same as this last one), I went back installed leptonica 
1.68 using configure, make, make install.  It seemed to be successful.

Did you try to run leptonica program?
If you look at config.log, you can see you have problem with leptonica 
instalation:

/usr/lib64/liblept.so: undefined reference to `TIFFWriteScanline'
/usr/lib64/liblept.so: undefined reference to `png_create_read_struct'
/usr/lib64/liblept.so: undefined reference to `jpeg_destroy'
/usr/lib64/liblept.so: undefined reference to `jpeg_simple_progression'
/usr/lib64/liblept.so: undefined reference to `png_set_pHYs'

Did you install (devel) libtiff, libpng libjpeg  libraries?

Found here (and worked for me):

"leptonica library missing"

For those on Ubuntu Natty 11.04, I had to add these to the top of my configure 
file:

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

For those on Debian 6 (Squeeze) the modification of configure file works also 
fine.

you do not have to modify configure! Just try:

LIBLEPT_HEADERSDIR=/usr/local/include ./configure

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

I put it to FAQ wiki

Perhaps there's something wrong with Debianised leptonica; I suspect it should 
depend upon the PNG/JPEG/TIFF libraries (beyond just "Depends: ...") but it 
doesn't seem to:

 root@mrnoisy:~# ldd /usr/lib/liblept.so
    linux-vdso.so.1 =>  (0x00007fff8bc69000)
    libc.so.6 => /lib/libc.so.6 (0x00007ff9aaa71000)
    /lib64/ld-linux-x86-64.so.2 (0x00007ff9ab12f000)

My workaround:

 CXXFLAGS="-ltiff -lpng -ljpeg" CPPFLAGS="-ltiff -lpng -ljpeg" ./configure

I 'm using Ubuntu 10.04.3 LTS and comment #6 option 2 also works

Just want to add my system that I forgot (comment #9 
http://code.google.com/p/tesseract-ocr/issues/detail?id=563#c7):

Debian GNU/Linux (6.0 / Squeeze), applied only security updates.

Late report: it didn't work (`make install`). My system didn't recognize it - I 
guess it's my own fault for not knowing how to make it work. But the comment #6 
- option 2 should work for everybody else (I guess) with the same problem.

Hi,
Did anyone of you solve that problem?

replay #7 is really help, but just set "-ltiff -lpng -ljpeg" is not enough.
I have to add  "-lz" (libz.so) so solve the problem(Mageia 2 64bit).

config.log is very detailed!

Additional, setting CXXFLAGS="-ltiff -lpng -ljpeg" CPPFLAGS="-ltiff -lpng 
-ljpeg" will cause the configure to use the lib twice. So I used 
CXXFLAGS="-ltiff -lpng -ljpeg -lz". Don't use CPPFLAG, it will cause problem in 
the make progress.
