最近在用Eclipse写C++程序，今天把Eclipse设置上踩过的坑总结一下

1. program 'g++' not found in path

解决方法：Eclipse上打开Window -> Preferences -> Build -> Settings -> Discovery，找到其中的“CDT GCC Built-in Compiler Settings"项，把${COMMAND} ${FLAGS} -E -P -v -dD "${INPUTS}"改为/usr/bin/${COMMAND} ${FLAGS} -E -P -v -dD "${INPUTS}"

改完成功解决问题

2. Symbol 'std' could not be resolved

解决方法：在Project上右键选择Properties，选择C/C++ General -> Path and Symbols -> Languages: GNU C++

Apply后问题解决
