我已经使用 eclipse 开发了一个 C++ 项目。当我Run从 IDE 中启动命令时，一切都会正常运行，并且程序会成功退出。这是使用 Eclipse 的 make 文件获得的构建输出：
**** Build of configuration Debug for project IVPM ****

我现在试图自己编写一个makefile，但无法成功编译。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
但是使用命令在shell上编译make会导致以下错误：
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

显然编译器无法找到标准库的匹配函数。但是我已经在我的编译选项中包含了 std 库，那么为什么编译器会抱怨呢？正确的程序是什么？
