当我运行alan@alan-virtual-machine:/projects/mini2440_android/kernel$ make uImage 命令时
出现make: arm-linux-gcc: Command not found错误。
但是我alan@alan-virtual-machine:/projects/mini2440_android/kernel$ echo $PATH
结果为 ~/Work/tools/jdk1.6.0_30/bin:~/Work/tools/jdk1.6.0_30/jre/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:~/work/tools/arm-eabi-4.4.0/bin:~/work/tools/arm-linux-gcc-4.4.3/bin
命令目录出现在alan@alan-virtual-machine:/projects/mini2440_android/kernel$ arm-linux-gccPATH中，
于是又命令alan@alan-virtual-machine:/projects/mini2440_android/kernel$ arm-linux-gcc
结果.arm-none-linux-gnueabi-gcc: no input files
命令alan@alan-virtual-machine:/projects/mini2440_android/kernel$ arm-linux-gcc -v
结果Using built-in specs.。。。（以下省略若干）
说明命令在路径中
于是在～/.profile中改export PATH=$PATH:~/work/tools/arm-eabi-4.4.0/bin:～/work/tools/arm-linux-gcc-4.4.3/bin
为export PATH=$PATH:~/work/tools/arm-eabi-4.4.0/bin:/home/alan/work/tools/arm-linux-gcc-4.4.3/bin
再运行make uImage一切正常。
不知为何make uImage命令时环境变量不能有～，但是一般的命令却没有问题。
