Question

我使用eclipse开发了一个C ++项目。当我从IDE中启动Run命令时，一切都会正常工作，程序会成功退出。这是使用Eclipse的make文件获得的构建输出：

**** Build of configuration Debug for project IVPM ****

**** Build Finished ****

我现在正试图自己编写一个makefile但是无法成功编译。这是我到目前为止所做的：

all:main

main:IVPM.o TemplateMatx3.o
    g++ IVPM.o TemplateMatx3.o -L/usr/local/lib -lopencv_core -lpng -lopencv_highgui -o main -c main.cpp

TemplateMatx3.o:TemplateMatx3.cpp
    g++ -I/usr/local/include/opencv -I/usr/local/include/opencv2 -I/usr/include/c++/4.5.2 -O0 -g3 -Wall -fmessage-length=0 -std=c++0x -c TemplateMatx3.cpp

IVPM.o:IVPM.cpp
    g++ -I/usr/local/include/opencv -I/usr/local/include/opencv2 -I/usr/include/c++/4.5.2 -O0 -g3 -Wall -fmessage-length=0 -std=c++0x -c IVPM.cpp

clean:
    rm -rf *o main

但是使用make命令在shell上进行编译将导致以下错误：

g++ -I/usr/local/include/opencv -I/usr/local/include/opencv2 -I/usr/include/c++/4.5.2 -O0 -g3 -Wall -fmessage-length=0 -std=c++0x -c IVPM.cpp

g++ IVPM.o TemplateMatx3.o -L/usr/local/lib -lopencv_core -lpng -lopencv_highgui -o main -c main.cpp

make: *** [main] Error 1

显然编译器无法找到std库的匹配函数。但是我在编译选项中包含了std库，为什么编译器会抱怨？什么是正确的程序？

make文件编译错误
