centos下安裝tessrect-ocr及訓練工具問題分析及解決辦法

最近要在服務器上搭建tessrect-ocr和訓練工具，搭建一個訓練網頁：

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

在搭建中遇到了以下問題：

1.找不到tessrect-ocr安裝包

2.訓練工具無法安裝

1.解決辦法：

[cpp]view plaincopy

1. sudoyuminstalltesseract.i686

2.安裝centos庫時，沒有安裝訓練工具，所以要進行源碼安裝：

1.下載源碼：

[cpp]view plaincopy

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

2.解壓：

unzip tesseract-master.zip

3.運行以下命令：

[cpp]view plaincopy

1. ./autogen.sh
2. ./configure
3. make
4. sudomakeinstall
5. sudoldconfig

現在已經安裝好引擎了，現在安裝訓練工具：

[cpp]view plaincopy

1. maketraining
2. sudomaketraining-install

但是如果你的程序在./configure時顯示這個：

[cpp]view plaincopy

1. Configurationisdone.
2. Youcannowbuildandinstalltesseractbyrunning:
4. $make
5. $sudomakeinstall
7. Youcannotbuildtrainingtoolsbecauseofmissingdependency.
8. Checkconfigureoutputfordetails.

那訓練工具肯定安裝不成功，因為它沒有生產Makefile文件

[cpp]view plaincopy

1. configure:creating./config.status
2. config.status:creatingMakefile
3. config.status:creatingtesseract.pc
4. config.status:creatingapi/Makefile
5. config.status:creatingccmain/Makefile
6. config.status:creatingopencl/Makefile
7. config.status:creatingccstruct/Makefile
8. config.status:creatingccutil/Makefile
9. config.status:creatingclassify/Makefile
10. config.status:creatingcube/Makefile
11. config.status:creatingcutil/Makefile
12. config.status:creatingdict/Makefile
13. config.status:creatingneural_networks/runtime/Makefile
14. config.status:creatingtextord/Makefile
15. config.status:creatingviewer/Makefile
16. config.status:creatingwordrec/Makefile
17. config.status:creatingtessdata/Makefile
18. config.status:creatingtessdata/configs/Makefile
19. config.status:creatingtessdata/tessconfigs/Makefile
20. config.status:creatingtesting/Makefile
21. config.status:creatingjava/Makefile
22. config.status:creatingjava/com/Makefile
23. config.status:creatingjava/com/google/Makefile
24. config.status:creatingjava/com/google/scrollview/Makefile
25. config.status:creatingjava/com/google/scrollview/events/Makefile
26. config.status:creatingjava/com/google/scrollview/ui/Makefile
27. config.status:creatingdoc/Makefile
28. config.status:creatingconfig_auto.h
29. config.status:config_auto.hisunchanged
30. config.status:executingdepfilescommands
31. config.status:executinglibtoolcommands

很明顯，沒有產生training的Makefile文件

下面解決辦法：

1.去看./configure產生的信息：

[cpp]view plaincopy

1. checkinglimits.husability...yes
2. checkinglimits.hpresence...yes
3. checkingforlimits.h...yes
4. checkingmalloc.husability...yes
5. checkingmalloc.hpresence...yes
6. checkingformalloc.h...yes
7. checkingforstdbool.hthatconformstoC99...yes
8. checkingfor_Bool...no
9. checkingwhether#!worksinshellscripts...yes
10. checkingforspecialCcompileroptionsneededforlargefiles...no
11. checkingfor_FILE_OFFSET_BITSvalueneededforlargefiles...64
12. checkingforgetline...yes
13. checkingforwchar_t...yes
14. checkingforlonglongint...yes
15. checkingforoff_t...yes
16. checkingformbstate_t...yes
17. checkingforleptonica...yes
18. checkingforl_generateCIDataForPdfin-llept...yes
19. checkingleptonicaheadersversion>=1.71...yes
20. checkingunicode/uchar.husability...yes
21. checkingunicode/uchar.hpresence...yes
22. checkingforunicode/uchar.h...yes
23. checkingforpkg-config.../usr/bin/pkg-config
24. checkingpkg-configisatleastversion0.9.0...yes
25. checkingforpango...yes
26. checkingforcairo...yes

如果有Warning：...............can't install training tools 按照其提示未安裝的進行按照:

如果找不到包,執行以下命令:

[cpp]view plaincopy

1. yumlist|gerpname

找到對應包。

這裡有一個包ICU版本比較舊，要進行源碼安裝：

1.下載源碼：

[cpp]view plaincopy

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

2. 安裝
[cpp]view plaincopy

1. ./configure
2. make
3. sudomakeinstall

然後重新運行./configure

如果沒有Warning但仍然顯示無法安裝：

修改config.status文件，325行添加 training/Makefile

然後進入training目錄，

執行

[cpp]view plaincopy

1. make
2. makeinstall
