qt 维护x86和arm两套编译环境

1、中间库：

中间库都放在middlewares目录，include头文件相同，所以不需要特殊处理，只要特殊处理lib安装目录，

示例pro文件如下：

TEMPLATE = lib 
TARGET = ime 
VERSION = 1.0.0 
DEPENDPATH += . 
INCLUDEPATH += .

CONFIG += staticlib

inc.files =  \ 
           xinputmethod.h

inc.files +=  $$HEADERS（引用变量的方法）

inc.path = ../includes

DEFINES += X86

contains( DEFINES, X86 ) { 
    message( "Configuring for X86 build..." ) 
    target.path = ../x86libs

} else { 
    message( "Configuring for arm build..." ) 
    target.path = ../libs 
}

INSTALLS += inc  target

2、应用程序方面：

pro文件中通过X86宏来控制链接库：

#DEFINES += X86 
contains( DEFINES, X86 ) { 
    message( "Configuring for X86 build..." ) 
    LIBS += -L /opt/qt-everywhere/marvell/APP/middlewares/x86libs/ -lime

} else { 
    message( "Configuring for arm build..." ) 
    LIBS += -L /opt/qt-everywhere/marvell/APP/middlewares/libs/ -lime 
}

INCLUDEPATH += /opt/qt-everywhere/marvell/APP/middlewares/includes 
DEPENDPATH += /opt/qt-everywhere/marvell/APP/middlewares/includes

OTHER_FILES += \ 
    ChangeLog.txt

Manually configuring shadow build in qmake

 mkdir my_shadow_build

 cd my_shadow_build

 qmake ../my_src_dir
