qtopia-2.2.0 make overriding commands --- 問題解決

原創 _借我你的一生_ 2020-02-22 17:27


沒注意看文字，其實 天嵌科技 已經標明瞭 “注意重複出現” 的問題，只是自己沒有注意。


今天按照 天嵌的 qtopia-2.2.0 製作 QT 應用程序，

按照手冊：

tmake -o Makefile second.pro
生成 Makefile 文件 . 如下：

make: *** [second] Error 1

出現了：overriding commands for target `moc_second.cpp'  的警告 ，即是  重複出現.

second.o:second.cpp:(.text+0x60): first defined here    說明被重複定義了.

查看 Makefile 文件：

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

SRCMOC	=	moc_second.cpp \
		moc_second.cpp
OBJMOC	=	moc_second.o \
		moc_second.o

moc_second.o: moc_second.cpp \
		second.h

moc_second.o: moc_second.cpp \
		second.h

moc_second.o: moc_second.cpp \
		second.h

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

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

發現很多的重複在裏面.

後來去掉了這些重複的代碼.

再 make . 

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

[root@localhost second]# make
make: *** 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 有錯誤.

查找到：INTERFACES：

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

可以看到  second.o \  多了一個 \ .

將其刪除，再 make.

[root@localhost second]# make
g++ -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.cpp
g++  -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 -lqte
cp -f second.desktop /opt/EmbedSky/Qte/x86-qtopia-2.2.0/qtopia/image/opt/Qtopia/apps/EmbedSky/second.desktop
cp -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.
