Apollo 快捷编译环境设置

Apollo 编译

------------------------------------------
Init:
------------------------------------------
Follow official process to source ./setup and make all

------------------------------------------
Build Env save & recover:
------------------------------------------
. In build terminal
  #sh ./build_save.sh

! build_save.sh
#!/bin/sh
env | sort |  grep -v "^_=" | grep -v "^OLDPWD=" | grep -v "^PWD=" > build_env
 
. New a terminal
  #source ./build_recover.sh
  and select "y"
 
! build_recover.sh
#!/bin/sh
env | sort > normal_env
diff build_env normal_env | grep ^\>
read CONFIRM
if [ $CONFIRM = y ]; then
diff build_env normal_env | grep ^\< | sed 's/^</export/g' > add_env
source ./add_env
fi

这样，我们甚至可以开很多terminal，都能编译项目。
