qtopia-2.2.0 make overriding commands --- 问题解决

没注意看文字，其实 天嵌科技 已经标明了 “注意重复出现” 的问题，只是自己没有注意。

今天按照 天嵌的 qtopia-2.2.0 制作 QT 应用程序，

按照手册：

tmake -o Makefile second.pro

生成 Makefile 文件 . 如下：

接着 make ：

出现了：overriding commands for target `moc_second.cpp'  的警告 ，即是  重复出现.

second.o:second.cpp:(.text+0x60): first defined here    说明被重复定义了.

查看 Makefile 文件：

OBJECTS =main.o \second.o \second.o

SRCMOC=moc_second.cpp \moc_second.cppOBJMOC=moc_second.o \moc_second.o

moc_second.o: moc_second.cpp \second.hmoc_second.o: moc_second.cpp \second.hmoc_second.o: moc_second.cpp \second.hmoc_second.cpp: second.h$(MOC) second.h -o moc_second.cppmoc_second.cpp: second.h$(MOC) second.h -o moc_second.cpp

发现很多的重复在里面.

后来去掉了这些重复的代码.

再 make . 

出现：make: *** No rule to make target`INTERFACES',

[root@localhost second]# makemake: *** No rule to make target `INTERFACES', needed by `/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qtopia/image/opt/Qtopia/bin/second'.  Stop.

看提示信息是 Makefile 有错误.

查找到：INTERFACES：

OBJECTS =main.o \second.o \INTERFACES =second.ui

可以看到  second.o \  多了一个 \ .

将其删除，再 make.

[root@localhost second]# makeg++ -c -pipe -DQWS -fno-exceptions -fno-rtti -Wall -W -O2 -DNO_DEBUG -I/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/include -I/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qtopia/include -o moc_second.o moc_second.cppg++  -o /opt/EmbedSky/Qte/x86-qtopia-2.2.0/qtopia/image/opt/Qtopia/bin/second main.o second.o  moc_second.o   -L/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qtopia/lib -L/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/lib -lqpe -lqtopia -lqtecp -f second.desktop /opt/EmbedSky/Qte/x86-qtopia-2.2.0/qtopia/image/opt/Qtopia/apps/EmbedSky/second.desktopcp -f second.png /opt/EmbedSky/Qte/x86-qtopia-2.2.0/qtopia/image/opt/Qtopia/pics/second.png

成功了，生成了所需的文件.
