M1 Mac（Sonoma 14.2.1）构建TPM2.0模拟器遇autoconf报错求助

问题 #

在运行macOS Sonoma（14.2.1）的M1 Mac上，尝试构建微软官方TPM 2.0参考实现的模拟器时，生成Makefile环节失败。执行以下步骤后出现报错：

询问是否存在缺失的配置或PATH设置，以链接autoconf修复该报错？

解决方案 #

报错AX_PTHREAD(, AC_MSG_ERROR([requires pthread]))是因为AX_PTHREAD宏的格式不兼容当前autoconf版本，或是autoconf无法正确读取autoconf-archive的宏文件。可按以下步骤修复：

• 指定autoconf宏文件路径
  autoconf-archive的宏文件默认存放在/usr/local/share/autoconf-archive，需要让autoconf能找到这个路径，执行：

  export ACLOCAL_PATH="/usr/local/share/aclocal:/usr/local/share/autoconf-archive"
  

• 重新生成构建脚本
  清理之前的构建残留，重新运行bootstrap：

  make distclean
  ./bootstrap
  

• 重新执行configure
  确保环境变量正确的前提下，再次运行configure：

  PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig" EXTRA_CFLAGS=-fno-common ./configure
  

• 手动修正宏调用格式（备选）
  如果上述步骤无效，可修改项目根目录的configure.ac文件，将AX_PTHREAD(, AC_MSG_ERROR([requires pthread]))改为：

  AX_PTHREAD([AC_MSG_ERROR([requires pthread])])
  

  修改后重新运行./bootstrap和configure。

• 确保brew工具优先级
  避免系统自带的旧版autoconf干扰，将brew安装的工具路径放到PATH最前面：

  export PATH="/usr/local/bin:$PATH"
