linux - arm-none-eabi 命令将无法正确安装

Question

我正在尝试在树莓派上安装用于汇编代码的工具链。我使用以下过程来安装包文件:

$ wget http://www.cl.cam.ac.uk/freshers/raspberrypi/tutorials/os/downloads/arm-none-eabi.tar.bz2

$ export PATH=$PATH:$HOME/arm-2008q3/bin

这似乎有效，包文件位于正确的位置。

 ~/arm-2008q3/bin $ ls
arm-none-eabi-addr2line  arm-none-eabi-gcc-4.3.2  arm-none-eabi-objdump
arm-none-eabi-ar         arm-none-eabi-gcov       arm-none-eabi-ranlib
arm-none-eabi-as         arm-none-eabi-gdb        arm-none-eabi-readelf
arm-none-eabi-c++        arm-none-eabi-gdbtui     arm-none-eabi-run
arm-none-eabi-c++filt    arm-none-eabi-gprof      arm-none-eabi-size
arm-none-eabi-cpp        arm-none-eabi-ld         arm-none-eabi-sprite
arm-none-eabi-g++        arm-none-eabi-nm         arm-none-eabi-strings
arm-none-eabi-gcc        arm-none-eabi-objcopy    arm-none-eabi-strip

但是，当我去制作时，我得到以下结果。

arm-none-eabi-as -I source/ source/main.s -o build/main.o
make: arm-none-eabi-as: Command not found
make: *** [build/main.o] Error 127

在此先感谢您的帮助。

Answer 1

export PATH=$PATH:$HOME/arm-2008q3/bin 仅在执行它的 shell 中有效(以及从该 shell 派生的任何 shell)。所以你要么使用那个 shell 而不是打开一个新的 shell 来执行 make 或编辑你的 ~/.bashrc (参见 Unix: Getting Export PATH to "Stick" )
