安装x86环境下支持调试loongarch体系结构的gdb

  1. docker中下载并解压：
wget http://ftp.gnu.org/gnu/gdb/gdb-12.1.tar.gz
tar -zxvf gdb-12.1.tar.gz 
cd gdb-12.1
mkdir build
cd build
../configure --prefix=/usr --target=loongarch64-unknown-linux-gnu
  1. 编译
make -j16
make install

注意：这里一定会报错：缺失了 expect 工具

apt-get install expect

在gdb-12.1/build/gdb目录下运行gdb可执行文件，看到下面信息说明安装成功：
