无法执行二进制文件:自定义Yocto层的Exec格式错误

Question

我想为CANBOAT储存库 phyBOARD米拉板创建一个Yocto层，它将连接到船上的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(Ubuntu16.04LTS)

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

我把所有的meta层都放在一个名为sources的文件夹中，在$YOCTO_DIR中。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是基于Yocto-Mega-制作手册的

#DEPENDS = "xsltproc"

SRCBRANCH = "master"
SRCREV = "93b2ebfb334d7a9750b6947d3a4af9b091be2432"

do_compile() {// this is not necessary for Yocto
    make
}
do_install() { // for Makefile Packages do_install is necessary
   oe_runmake install DESTDIR=${D}
}

生成和错误

在build目录中执行

  bitbake canboat

并获取错误日志：

我了解到，-x86_64二进制文件在gnueabi平台上可能不兼容。为了克服这种不兼容性，我如何编译这个存储库？

Answer 1

答案取决于二进制程序做了什么:二进制的结果是否取决于工具运行的体系结构？如果你在问题中添加细节，可能会有人提供一个更详细的答案。

选项1:如果该工具的结果独立于体系结构，那么您可以首先编译一个“原生”版本(即构建主机拱形)版本，然后确保目标构建依赖于本机构建，并使用来自本机构建的工具。这将意味着食谱中的小变化和Makefile中的一些更改。

选项2:如果结果确实取决于arch，您可能必须使用qemu来运行该工具。

这两种情况的例子都存在于棘手的来源中。

可能还有第三种选择:如果构建不需要文件才能成功，则可以在第一次引导/安装时在postinstall脚本中运行该工具(并修改生成系统，使其在构建过程中不执行)。
