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

wuliwei85

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
