在linux下面安裝arm交叉編譯工具，實(shí)現(xiàn)下載、調(diào)試

下載安裝包

如果用sudo apt-get remove gcc-arm-none-eabi 安裝的交交叉編程工具，是沒有含GDB工具的，所以需要卸載后才能安裝。

sudo apt-get remove gcc-arm-none-eabi就可以完成卸載，如果還有在/usr/bin/arm-none-eabi-下面的文件有沖突的，先要?jiǎng)h除才能安裝成功。

安裝包下載網(wǎng)址：Downloads | GNU Arm Embedded Toolchain Downloads – Arm Developer

我的虛擬機(jī)是x86的，所以下載以下文件。下載速度很慢的，可以復(fù)制鏈接，用下載工具下載。

安裝

我試著按其人的安裝教程，想把文件解壓到/usr/share/目錄下，但是好象不能成功。我所以在/opt/下面新建了gdb文件夾，并修改權(quán)限。

然后解壓到這個(gè)文件夾下面：

tar -jxvf gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2 -C /opt/gdb/

最后創(chuàng)建軟件連接到/usr/bin/目錄下面：

sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-objcopy /usr/bin/arm-none-eabi-objcopy
sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-objdump /usr/bin/arm-none-eabi-objdump 
sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-gcc /usr/bin/arm-none-eabi-gcc
sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-g++ /usr/bin/arm-none-eabi-g++
sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-gdb /usr/bin/arm-none-eabi-gdb
sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-szie /usr/bin/arm-none-eabi-size
sudo ln -s /opt/gdb/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-as /usr/bin/arm-none-eabi-as

執(zhí)行調(diào)試：

總結(jié)

我前面因?yàn)間db沒有安裝成功，后面去下載源碼進(jìn)行編譯，花了很長的時(shí)間，最后在Downloads | GNU Arm Embedded Toolchain Downloads – Arm Developer下載包進(jìn)行直接解壓，快速方便。
