eclipse+CDT+MinGW问题

想用eclipse+CDT+MinGW搞个C++开发环境，都装好之后新建helloworld项目，编译没有通过：
**** Internal Builder is used for build ****
g++ -O0 -g3 -Wall -c -fmessage-length=0 -osrc\test.o ..\src\test.cpp

高手们帮忙看看是怎么回事啊？ 多谢了
环境变量都设置了的

Answer 1

我开始也是跟你一样的错误。
后来将下载的lzma一起用7-zip解压两次就可以了。不知道为什么。
设置的路径为
set MinGW_PATH=D:\Program\MinGW
path = %path%;%MinGW_PATH%\bin;%MinGW_PATH%\mingw32\bin

Answer 2

||运算符有个特点，就是只要出现1就不会执行剩下的运算
所以++x||++y&&++z;中只会执行++x,剩下的++y&&++z不会被运行到。

Answer 3

你的makefile有问题吧
你的串号我已经记下，采纳后我会帮你制作
