我想为phyBOARD Mira板的CANBOAT存储库创建一个Yoto层，该层将连接到船上的NMEA2000。我想读取不同的PGN值并将其存储在数据库中。
配置
我有一个 Linux 虚拟机 (Ubuntu 16.04 LTS)
Linux ubuntu 4.13.0-39-generic #44~16.04.1-Ubuntu SMP Thu Apr 5 16:43:10 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
我将所有meta图层都放在一个名为sources的文件夹中$YOCTO_DIR.在sources中，我创建了具有以下结构的meta-canboat层：
├── conf
│ └── layer.conf
├── COPYING.MIT
├── README
└── recipes-canboat
└── canboat
└── canboat.bb
canboat.bb基于Makefile的Yocto-Mega-Manual

构建和错误
在我执行的build目录中
bitbake canboat
并获取错误日志：

我知道gnueabi平台上的-x86_64二进制文件可能不兼容。如何编译此存储库以克服这种不兼容性？

答案取决于二进制文件的作用：二进制文件的结果是否取决于运行该工具的体系结构？如果您为问题添加详细信息，有人可能会提供更详细的答案。
选项 1：如果工具结果独立于架构，那么您可以首先编译 canboat 的"本机"(即构建主机架构)版本，然后确保目标构建依赖于本机构建并使用本机构建中的工具。这将意味着配方中的小变化和制作文件中的一些变化
选项 2：如果结果确实取决于 arch，则可能必须使用 qemu 来运行该工具。
在poky来源中都有这两种情况的例子。
可能还有第三种选择：如果构建成功不需要这些文件，则可以在首次启动/安装时在安装后脚本中运行该工具(并修改构建系统以在构建期间不执行此操作)。
