'make' KDIR=/lib/modules/5.15.0-1023-azure/build....（錯誤退出狀態：2）

Question

我正在嘗試使用 os ubuntu 20.04 https://www.intel.com/content/www/us/en/developer/articles/guide/intel-software-guard-extensions-data-center上的鏈接安裝 SGX DCAP -attestation-primitives-quick-install-guide.html當我運行命令sudo./sgx_linux_x64_driver_1.36.2.bin

I get error:
Unpacking Intel SGX Driver ... done.
Verifying the integrity of the install package ... done.

Kernel preparation unnecessary for this kernel.  Skipping...

這是dpkg-query -s linux-headers-$(uname -r)的結果

這是運行命令ls -la /dev/sgx*的結果

有沒有人知道原因？

SGX DCAP的安裝過程與azure不同，驅動已經安裝好了（以DCsV3 VM為例）。 事實上，它有自己的插件，您可以在此處找到https://github.com/microsoft/Azure-DCAP-Client 。 或者，您可以使用以下方式直接安裝它：

curl -sSL https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
sudo apt-add-repository https://packages.microsoft.com/ubuntu/{your ubuntu distribution}/prod
sudo apt-get update
sudo apt-get install az-dcap-client
ln -s /usr/lib/libdcap_quoteprov.so /usr/lib/x86_64-linux-gnu/libdcap_quoteprov.so.1

PS：確保您使用支持 Intel SGX 的 VM。
