make: *** No rule to make target `all'. Stop.

环境：Eclipse + CDT + Mingw

?

项目类型：C Project-->Makefile project-->Empty Project-->MinGW GCC

?

错误：

make all
make: *** No rule to make target `all'.? Stop.

?

解决方式：右键项目-->properties-C/C++ Build-->Builder settings

?????????????? 此时可看到Builder Type是不可选的，

?????????????? 且Makefile generation-->Generate makefiles automatically是未选中的

?????????????? 选中Generate makefiles automatically

?????????????? 此时Builder Type变成了可选项，选择internal builder

?????????????? 然后提交

?

执行项目，如果再出现Launch failed. Binary not found.错误，刷新下项目就好了，或者Project-->Build All

?
