pb install on redhat PKG_CHECK_MODULES(LEPTONICA

[Jean-Christophe Penalva]

  Hello,

  i try to compile the new version of Tesseract (v4.0x) on a redhat from source. I've already compile and install the libleptonica, and now i've a pb during the configure stage of tesseract :

export CFLAGS=-I...../leptonica/1.74.1/include

export CPPFLAGS=-I......../leptonica/1.74.1/include

export LDFLAGS=-L......./leptonica/1.74.1/lib

./configure --prefix=......./tesseract/4.0 --with-extra-includes=......./leptonica/1.74.1/include --with-extra-libraries=......../leptonica/1.74.1/lib

...

....

checking for long long int... yes

checking for off_t... yes

checking for mbstate_t... yes

./configure: line 16347: syntax error near unexpected token `LEPTONICA,'

./configure: line 16347: `PKG_CHECK_MODULES(LEPTONICA, lept >= 1.74, have_lept=true, have_lept=false)'

I search for a this message ... but nothing. Is it possible to install tesseract from sources (and from sources of leptonica too) ?

[ShreeDevi Kumar]

I built both from source yesterday.

Try the following for building tesseract

/autogen.sh
./configure
LDFLAGS="-L/usr/local/lib" CFLAGS="-I/usr/local/include" make
sudo make install
sudo ldconfig

It seems like problem with pkg-config. Do you have it installed?

pkgconfig-0.23-9.1.el6.x86_64

  and in the lib directory of the installed libleptonica, there are these files :

-rw-r--r-- 1  15994844 Apr 25 10:03 liblept.a

-rwxr-xr-x 1       999 Apr 25 10:03 liblept.la

lrwxrwxrwx 1        16 Apr 25 10:03 liblept.so -> liblept.so.5.0.1

lrwxrwxrwx 1        16 Apr 25 10:03 liblept.so.5 -> liblept.so.5.0.1

-rwxr-xr-x 1   9533600 Apr 25 10:03 liblept.so.5.0.1

drwxrwxr-x 2      4096 Apr 25 10:03 pkgconfig

IMHO you need to set PKG_CONFIG_PATH to your custom location of leptonica, so pkg-config is able to find lept.pc.

  i've already the PKG_CONFIG_PATH ok !!

env | grep PKG

PKG_CONFIG_PATH=/...../leptonica/1.74.1/lib/pkgconfig

and pkg-config is running well :

pkg-config --cflags --libs lept

-I/....../leptonica/1.74.1/include/leptonica  -L/...../leptonica/1.74.1/lib -llept

  Finally, i use the cmake.

  mkdir build

  cd build

  ccmake ..

  make

  And no more problems !

I just building tesseract4.0 in CentOS5.5  and with solved a lot of problem ....final i run ./configure   and  have the same problem like you ...

checking for off_t... yes

checking for mbstate_t... yes

./configure: line 17743: syntax error near unexpected token `LEPTONICA,'

./configure: line 17743: `PKG_CHECK_MODULES(LEPTONICA, lept >= 1.74, have_lept=true, have_lept=false)'

and i check the things like you....

[root@marineap tesseract-ocr]# pkg-config --cflags --libs lept

-I/usr/local/include/leptonica  -L/usr/local/lib -llept  

[root@marineap build]# echo $PKG_CONFIG_PATH

/usr/local/lib/pkgconfig::/my/additional/config:/usr/local/lib/pkgconfig/

it's all contain lept

could you tell me ..Tell me how you installed it in detail...

i have spent a lot of time in it...it make me feel a liitle bad...
