用scons构建cppcheck的GUI程序
关于linux上下载cppcheck及配置Qt环境等信息，可
参见我的上一篇文章 《64位centos上用Qt编译生成c/c++代码检查工具cppchek的GUI》
假定cppcheck下载后，存放在本地的路径为：/usr/tools/cppcheck-1.44
scons构建脚本文件目录结构如图所示
cppcheck-1.44 sconstruct文件
|
|---cli sconscript文件
|
|---gui sconscript文件
|
|---test sconscript文件
|
|---....
1、sconstruct文件，内容如下：
#!/usr/bin/python
import os
bin = '#bin'
myhome = os.getcwd()
env = Environment(
tools=['default','qt'],
ENV = os.environ,
CXXFLAGS = '-O2 -DNDEBUG -Wall -Ilib',
BINDIR = bin,
LIBS=[],
#QTDIR='/opt/qtsdk/qt'
)
Export('env','myhome')
subdir = ['./test','./cli','./gui']
for i in subdir:
env.SConscript('%s/sconscript' %(i) )
2、cli/sconscript文件，内容如下：
#!/usr/bin/python
import os
Import('env','myhome')
lib_files = Glob('%s/lib/*.cpp' %(myhome))
cli_files = Glob('%s/cli/*.cpp' %(myhome))
bin_cppcheck = env.Program(target='cppcheck',
source=[cli_files,lib_files],
CPPPATH= '%s/lib' %(myhome) )
cppcheck_install = env.Install('$BINDIR', bin_cppcheck)
env.Default(cppcheck_install);
3、gui/sconscript文件，内容如下：
#!/usr/bin/python
import os
import glob
Import('env','myhome')
def recursiveDirs(root) :
return filter( (lambda a : a.rfind( "SVN")==-1 ), [ a[0] for a in os.walk(root)] )
def unique(list) :
return dict.fromkeys(list).keys()
def scanFiles(dir, accept=["*.cpp"], reject=[]) :
sources = []
paths = recursiveDirs(dir)
for path in paths :
for pattern in accept :
sources+=glob.glob(path+"/"+pattern)
for pattern in reject :
sources = filter( (lambda a : a.rfind(pattern)==-1 ), sources )
return unique(sources)
lib_files = Glob('%s/lib/*.cpp' %(myhome))
temp_files = Glob('temp/*.cpp')
gui_files = Glob('*.cpp')
cpp_path = ['/opt/qtsdk/qt/mkspecs/linux-g++-64',
'/opt/qtsdk/qt/include',
'/opt/qtsdk/qt/include/QtCore',
'/opt/qtsdk/qt/include/QtGui',
'/opt/qtsdk/qt/include/QtXml',
'%s/gui/temp' %(myhome),'%s/gui' %(myhome)
]
lib_path = ['/opt/qtsdk/qt/lib','/usr/lib','/usr/X11R6/lib64']
ui_dir=['resultsview','application','main','settings','file','about']
for ui in ui_dir:
env.Execute("/opt/qtsdk/qt/bin/uic -o %s/gui/temp/ui_%s.h %s/gui/%s.ui" %(myhome,ui,myhome,ui))
# env.Uic(target="%s/gui/temp/ui_%s" %(myhome,ui),source=ui) 注：执行Uic接口有点问题
#for qrc in scanFiles('/usr/tools/cppcheck-1.44/gui', ['*.qrc']):
#print "hua:"+qrc
#env.Qrc(qrc, QT4_QRCFLAGS='-name '+'gui gui.qrc')
env.Execute('/opt/qtsdk/qt/bin/rcc -name gui gui.qrc -o temp/qrc_gui.cpp')
bin_gui = env.Program(target='gui',
source=[lib_files,gui_files,temp_files],
CPPPATH = cpp_path,
LIBPATH = lib_path,
LIBS=['QtGui','QtCore','QtXml','pthread']
)
gui_install = env.Install('$BINDIR', bin_gui)
env.Default(gui_install);
4、test/sconscript文件，内容如下：
#!/usr/bin/python
import os
Import('env','myhome')
lib_files = Glob('%s/lib/*.cpp' %(myhome))
cli_files = '%s/cli/threadexecutor.cpp' %(myhome)
test_files = Glob('*.cpp')+Glob('tinyxml/*.cpp')
bin_testrunner = env.Program(target='testrunner',
source=[test_files,lib_files,cli_files],
CPPPATH = ['%s/cli' %(myhome)])
test_install = env.Install('$BINDIR', bin_testrunner)
env.Default(test_install);
5、执行构建脚本
$cd /usr/tools/cppcheck-1.44
$scons即可
6、解决gui可执行程序运行不成功
在编译成功gui，生成可执行文件后，运行该可执行文件，系统提示错误信息：“error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory”
解决办法：
（1）查找libQtGui.so.4所在目录
$find /opt/qtsdk |grep libQtGui.so.4
/opt/qtsdk/qt/lib/libQtGui.so.4
/opt/qtsdk/qt/lib/libQtGui.so.4.6.3
/opt/qtsdk/qt/lib/libQtGui.so.4.6
/opt/qtsdk/lib/libQtGui.so.4
/opt/qtsdk/lib/libQtGui.so.4.7.0
（2）ld文件配置
$vi /etc/ld.so.conf
include id.so.conf.d/*.conf //里面只有一行，表示到id.so.conf.d目录中寻找配置信息
$cd /etc/ld.so.conf.d //转到Id.so.conf.d目录下
在该目录下会看到qt-i386.conf
修改Id路径
$vi qt-i386.conf //编辑qt-i386.conf文件
#/usr/lib/qt-3.3/lib //屏蔽默认指向qt-3.3的语句
/opt/qtsdk/qt/lib //增加指向qt4.6.3所在的目录
（3）设置完ld路径后，需要运行ldconfig命令，更新缓存
做完上述后，即可运行成功gui程序
