Configure error(configure: error: Leptonica 1.74 or higher is required. Try to install libleptonica-dev package.) in Amazon Linux

[khana...@vitalify.jp]

During configure, error occurs.

checking for LEPTONICA... no 

configure: error: Leptonica 1.74 or higher is required. Try to install libleptonica-dev package.

But, I have installed leptonica-1.77.0.

 

・Environment

• Tesseract Version: master 4.0.0 (2019-01-03)
• Commit Number: 3377ed2
• Platform: Amazon Linux AMI release 2018.03

・Issue command

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LIBLEPT_HEADERSDIR=/usr/local/include/leptonica
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/

./configure --with-extra-libraries=/usr/local/lib

Please enlighten me on the specifics.

What does it mean?

./configure --with-extra-libraries=/usr/local/lib

/usr/local is standard lib path, so IMO there is not need to add it to configure (but maybe this is not true on each distribution ;-) ).

Anyway leptonica presence is detected by pkg-config.Check config.log why it failed to find leptonica. Do you have more leptonica installations (e.g /usr and /usr/local)?

 

Please enlighten me on the specifics.

Thanks for the reply.

I explain how to install Tesserac to you.

At first, I installed leptonica-1.77.0.
```

[ec2-user@xxx ~]$ 

[ec2-user@xxx leptonica-1.77.0]$ cd leptonica-1.77.0/

[ec2-user@xxx leptonica-1.77.0]$ sudo ./autogen.sh 

[ec2-user@xxx leptonica-1.77.0]$ sudo ./configure

[ec2-user@xxx leptonica-1.77.0]$ sudo make

[ec2-user@xxx leptonica-1.77.0]$ sudo make install

```

Second, I tyried installing tesseract

But, configure error occurs at "sudo ./configure 

```

[ec2-user@xxx ~]$ cd lib/tesseract/

[ec2-user@xxx tesseract]$ sudo ./configure

checking for g++... g++

checking whether the C++ compiler works... yes

checking for C++ compiler default output file name... a.out

・

・

・

checking pkg-config is at least version 0.9.0... yes

checking for LEPTONICA... no

configure: error: Leptonica 1.74 or higher is required. Try to install libleptonica-dev package.

```

Installing  leptonica-1.77.0 was successful.

But, "configure: error" occurs...

As I wrote:

check config.log why pkg-config failed to find leptonica (or port somewhere config.log)

I solved ,thanks to you.

I checked  /home/ec2-user/lib/tesseract/config.log

In this file, PKG_CONFIG_PATH=''

When I issued sudo ./configure, OS can't keep environment variable of ec2-user.

Thus,  PKG_CONFIG_PATH=''.

So,

I issued sudo su

and,

export PKG_CONFIG_PATH='/usr/local/lib/pkgconfig'

./configure

make

make install

sudo ldconfig

Installing  tesseract 4.0.0-133-g3377was successful.

Thanks!!
