eclipse 실행후 main.cpp 만들어서 실행 해보니...
**** Build of configuration Debug for project hello ****
make all
Building target: hello
Invoking: GCC C++ Linker
g++ -o"hello" ./main.o
/usr/lib/gcc/i386-redhat-linux/4.1.1/../../../crt1.o: In function `_start':
(.text+0x18): undefined reference to `main'
collect2: ld returned 1 exit status
make: *** [hello] Error 1

build 하면 자동 저장이 안되네. ^^
