编译tpm模拟器错误

Question

尝试在Ubuntu 32位下编译TPM-Emulator。设置export ARCH=i386，具有

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

我得到了类似的错误

[ 98%] Generating linux/tpmd_dev.ko
/home/tomasz/Git/tpm-emulator/build/tpmd_dev/linux/tpmd_dev.c: In function ‘tpmd_handle_command’:
/home/tomasz/Git/tpm-emulator/build/tpmd_dev/linux/tpmd_dev.c:111:6: error: ‘struct msghdr’ has no member named ‘msg_iov’
   msg.msg_iov = &iov;
      ^

Answer 1

EDIT: IBM有一个兼容TPM 2.0的TPM模拟器，在这里

在git的repo中，你链接了一个用户为修复你的问题而发出的pull请求。这对我有用(有一些空白修复，我没有使用。如果补丁出现问题，请手动更改)。
