本文描述了在Ubuntu20.04上安装IntelSGX驱动的步骤，包括下载.bin文件，赋予执行权限，以及解决安装过程中遇到的gcc缺失和CONFIG_X86_X32支持问题。通过安装gcc和binutils，最终成功安装驱动。

driver安装

1.将3个.bin文件下载(右键另存为即可)，下载地址：https://download.01.org/intel-sgx/latest/linux-latest/distro/ubuntu20.04-server/

2.到下载文件夹下,输入下面命令，是给.bin文件一个执行权限

sudo chmod 777 sgx_linux_x64_driver_2.11.054c9c4c.bin

3. 运行该bin文件，完成驱动安装

sudo ./ sudo chmod 777 sgx_linux_x64_driver_2.11.054c9c4c.bin

在驱动安装时候报错：

Warning: There is no need to install additional SGX driver with in-kernel SGX support.
/opt/intel/sgxdriver/package /home/lyx/SGXziliao
make -C /lib/modules/5.15.0-46-generic/build M=/opt/intel/sgxdriver/package modules
make[1]: 进入目录“/usr/src/linux-headers-5.15.0-46-generic”
arch/x86/Makefile:142: CONFIG_X86_X32 enabled but no binutils support
make[1]：gcc：命令未找到
warning: the compiler differs from the one used to build the kernel
  The kernel was built by: gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0
  You are using:           
  CC [M]  /opt/intel/sgxdriver/package/sgx_main.o
/bin/sh: 1: gcc: not found

这是因为没有gcc，我们采用下面指令安装gcc

$ sudo apt install gcc automake autoconf libtool make

还有一个问题是：CONFIG_X86_X32已启用，但不支持binutils

   arch/x86/Makefile:142: CONFIG_X86_X32 enabled but no binutils support,

采用指令：

$ sudo apt-get install binutils

最终第三步执行bin文件安装驱动成功，终端代码如下：
