CenOS with CutyCapt
一 安裝QT44
二 把安裝QT44目錄寫到環境參數中
三 下載軟體編譯安裝
四 安裝x-server
五 Dbug
安裝QT44解碼器居然有三種方法
1. rmp包安裝
2. 增加源安裝
3. Centos 6.X 直接yum安裝更新版確實方便
rpm 安裝
安裝 QT44 解碼器
(x86)
wget http://ftp.riken.go.jp/Linux/atrpms/el5-i386/atrpms/testing/qt44-4.4.3-10_4.el5.i386.rpm
wget http://ftp.riken.go.jp/Linux/atrpms/el5-i386/atrpms/testing/qt44-x11-4.4.3-10_4.el5.i386.rpm
wget http://ftp.riken.go.jp/Linux/atrpms/el5-i386/atrpms/testing/qt44-devel-4.4.3-10_4.el5.i386.rpm
(x64)
wget http://dl.atrpms.net/el5-x86_64/atrpms/testing/qt44-4.4.3-10_4.el5.x86_64.rpm
wget http://dl.atrpms.net/el5-x86_64/atrpms/testing/qt44-x11-4.4.3-10_4.el5.x86_64.rpm
wget http://dl.atrpms.net/el5-x86_64/atrpms/testing/qt44-devel-4.4.3-10_4.el5.x86_64.rpm
rpm -ivh qt44-4.4.3-10*
rpm -ivh qt44-x11-4.4.3-10*
rpm -e qt-devel –nodeps –allmatches
rpm -ivh qt44-devel-4.4.3-10*
rpm -rebuilddb
這一步如果不成功的話應該是各種依賴的問題
可以安裝 qt-devel 依賴包
yum install libXi-devel
yum install libXinerama-devel
也許這裏還會有報錯提示
warning: qt44-x11-4.4.3-10_4.el5.x86_64.rpm: Header V4 DSA signature: NOKEY, key ID 66534c2b
error: Failed dependencies:
libGLU.so.1()(64bit) is needed by qt44-x11-4.4.3-10_4.el5.x86_64
libmng.so.1()(64bit) is needed by qt44-x11-4.4.3-10_4.el5.x86_64
執行代碼：
yum -y install qt-devel*
提示依賴什麼就裝什麼。
可以用 yum search packName 來找有沒有這個包
如：yum search qt-devel
如果結果結果有包，那麼安裝時上執行 yum -y install qt-devel* 安裝，加*號是為了安裝上它所有的依賴包
增加源安裝
CentOS 5.x 安裝教程如下：
Add this to /etc/yum.repos.d/CentOS-Base.repo
#ATrpms
[atrpms]
name= CentOS-$releasever – ATrpms
baseurl=http://dl.atrpms.net/el$releasever-$basearch/atrpms/testing
gpgcheck=1
gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms
enabled=1
rpm –import http://packages.atrpms.net/RPM-GPG-KEY.atrpms
yum install subversion qt47-devel qt47-webkit gcc-c++ qt47-webkit-devel sqlite
centos 6.x安裝
安裝gc-c++
yum install gcc-c++
安裝Qt依懶
yum install qt
yum install qt-devel
安裝的目錄在：
/usr/lib64/qt4
qmake 可以用 /usr/lib64/qt4/bin/qmake 執行
環境變數配置
加入 QT 目錄到環境參數中 如果是32位元系統刪除下面紅字的64
vim /etc/profile
#==================================================
export QTDIR=/usr/lib64/qt44
export QTLIB=/usr/lib64/qt44/lib
export QTINC=/usr/lib64/qt44/include
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export PATH=$QTDIR/bin:$PATH
#==================================================
保存退出後，運行一次該檔
source /etc/profile
編譯程序
% svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt （沒有svn的yum install subversion）h
% cd cutycapt/CutyCapt
% qmake
% make
如果沒有X server的話需要使用xvfb-run：
wget http://www.flexthinker.com/wp-content/uploads/2009/11/xvfb-run.sh.txt
mv ./xvfb-run.sh.txt ./xvfb-run.sh
chmod u+x ./xvfb-run.sh
./xvfb-run.sh –server-args=”-screen 0, 1024x768x24″ /home/xxx/cutycapt/CutyCapt/CutyCapt –url=http://www.163.com –out=163.jpg
dbug
qmake
make
出現以下錯誤
/usr/lib64/qt47/libQtWebKit.so: undefined reference to `sqlite3_prepare16_v2′
/usr/lib64/qt47/libQtWebKit.so: undefined reference to `sqlite3_column_value’
collect2: ld returned 1 exit status
make: *** [CutyCapt] Error 1
解決：
yum update sqlite
再次執行
make
如果還不成功
qmake-qt47
再次執行make
以下表示make成功
[root@localhost CutyCapt]# make
g++ -Wl,-O1 -o CutyCapt CutyCapt.o moc_CutyCapt.o -L/usr/lib64/qt47 -lQtWebKit -lQtSvg -L/usr/lib64/qt47 -lQtGui -lQtNetwork -lQtCore -lpthread
執行
xvfb-run –server-args=”-screen 0, 1024x768x24″ ./CutyCapt –url=http://www.baidu.com/ –out=localfile1.png –body-string=utf-8
出現-bash: xvfb-run: command not found
安裝
yum install Xorg Xvfb xauth xorg-x11-fonts*
不知道為什麼安裝後 沒有自動生成xvfb-run
下載並上傳xvfb-run腳本到
/usr/bin
chmod +x xvfb-run
運行 ../../xvfb-run.sh ./CutyCapt –url=http://www.baidu.com/ –out=localfile1.png –body-string=utf-8

BUG描述：
運行用Swing的APP時，會無法啟動，顯示類似於”Assertion `c->xlib.lock’ failed.”的
問題
如Zend Studio和NetBeans無法正常啟動，官方解釋這是由於使用了XCB而不是LibX的緣故
，關鍵就在於assert時，Lock問題。一種解決方案是回去使用libx，另一種則是去掉asse
rt時的檢查。
下面的解決方案可行，(試過。)

Here’s one explaination:
Re: NB doesn’t work in open suse 10.3 “Assertion `c->xlib.lock’ failed.”

This is the solution–> just add this to your Environment
export LIBXCB_ALLOW_SLOPPY_LOCK=1
========================================
也就是運行程式前先運行
export LIBXCB_ALLOW_SLOPPY_LOCK=1
再次運行
xvfb-run –server-args=”-screen 0, 1024x768x24″ ./CutyCapt –url=http://www.baidu.com/ –out=localfile1.png –body-string=utf-8
等一會見到生成了localfile1.png表示成功了
不過每次都輸入
export LIBXCB_ALLOW_SLOPPY_LOCK=1 有點麻煩
大神給了個解決方法
cat > run
vi run
輸入
export LIBXCB_ALLOW_SLOPPY_LOCK=1
../../xvfb-run.sh ./CutyCapt –url=$1 –out=$2 –body-string=$3
保存退出
chmod +x ./run
./run http://www.baidu.com test.jpg, utf-8
依次輸入 $1 http://www.baidu.com $2 圖片名 $3字體
截圖成功
如果中文不能正常顯示的話，需要安裝字體檔
yum install fo nts-chinese
