Installation of tessrect-ocr and training tools in centos

Recently, we have to build a tessrect-ocr and training tool on the server to build a training webpage:

Http: // 115.159.205.168/ocr_php/public/index. php

The following problems were encountered during setup:

1. The tessrect-ocr installation package cannot be found.

2. The training tool cannot be installed.

1. solution:

[Cpp] view plaincopy

1. Sudoyuminstalltesseract. i686

2. When installing the centos library, the training tool is not installed, so you need to install the source code:

1. Download the source code:

[Cpp] view plaincopy

1. Wgethttps: // github.com/tesseract-ocr/tesseract/archive/master.zip

2. decompress:

Unzip tesseract-master.zip

3. Run the following command:

[Cpp] view plaincopy

1. ./Autogen. sh
2. ./Configure
3. Make
4. Sudomakeinstall
5. Sudoldconfig

Now that the engine has been installed, install the training tool:

[Cpp] view plaincopy

1. Maketraining
2. Sudomaketraining-install

However, if your program displays this in./configure:

[Cpp] view plaincopy

1. Configurationisdone.
2. Youcannowbuildandinstalltesseractbyrunning:
4. $ Make
5. $ Sudomakeinstall
7. Youcannotbuildtrainingtoolsbecauseofmissingdependency.
8. Checkconfigureoutputfordetails.

The training tool cannot be installed because it does not produce the Makefile file.

[Cpp] view plaincopy

1. Configure: creating./config. status
2. Config. status: creatingMakefile
3. Config. status: creatingtesseract. pc
4. Config. status: creatingapi/Makefile

28. Config. status: creatingconfig_auto.h
29. Config. status: config_auto.hisunchanged
30. Config. status: executingdepfilescommands
31. Config. status: executinglibtoolcommands

Obviously, no Makefile for training is generated.

The following solution:

1. view the information generated by./configure:

[Cpp] view plaincopy

1. Checkinglimits. husability... yes
2. Checkinglimits. hpresence... yes
3. Checkingforlimits. h... yes
4. Checkingmalloc. husability... yes

25. Checkingforpango... yes
26. Checkingforcairo... yes

If Warning:... can't install training tools, follow the prompts below:

If the package cannot be found, run the following command:

[Cpp] view plaincopy

1. Yumlist | gerpname

Find the corresponding package.

Here is a pack of old ICU versions, which requires source code installation:

1. Download the source code:

[Cpp] view plaincopy

1. Wgethttp: // download.icu-project.org/files/icu4c/58.1/icu4c-58_1-src.tgz

2. Installation
[Cpp] view plaincopy

1. ./Configure
2. Make
3. Sudomakeinstall

Then run./configure again.

If there is no Warning, but it still shows that the installation is not possible:

Modify the config. status File and add the training/Makefile in line 325.

Then go to the training Directory,

Run

[Cpp] view plaincopy

1. Make
2. Makeinstall
