只是想在 Ubuntu 32 位下编译TPM-Emulator 。设置export ARCH=i386,有

tomasz@tomasz-VirtualBox:~/Git$ find /usr/include -name socket.h
/usr/include/asm-generic/socket.h
/usr/include/linux/socket.h
/usr/include/i386-linux-gnu/asm/socket.h
/usr/include/i386-linux-gnu/sys/socket.h
/usr/include/i386-linux-gnu/bits/socket.h

我得到类似的错误

[ 98%] Generating linux/tpmd_dev.ko

   msg.msg_iov = &iov;

编辑： IBM 有一个符合 TPM 2.0 的 TPM 模拟器，这里

在 git 存储库中，您链接的用户提出了修复您的问题的拉取请求。这对我有用（有一些我没有使用的空白修复。如果补丁出现问题，只需手动进行更改）。
