我正在尝试按照本教程构建 PetaLinux 2018.2 映像。为此，我使用了 PetaLinux 工具本身不支持的 Fedora 33。一切都很顺利，直到petalinux-build必须运行的第 3 步。这个命令，经过一些计算，打印出这个长的错误信息：

这里有很多不同的错误，特别是我想解决这个：
Subprocess output:

正如在这个答案（我之前的问题）中指出的那样，/home/MY_USER/path/Project/xilinx-zc702-2018.2/build/tmp/sysroots-uninative/x86_64-linux/lib/libc.so.6和之间存在依赖关系/lib64/libgomp.so.1，第一个属于我的图像，第二个属于我的 Fedora 33 系统。
运行/home/MY_USER/path/Project/xilinx-zc702-2018.2/build/tmp/sysroots-uninative/x86_64-linux/lib/libc.so.6返回：

所以，这个输出是连贯的，因为libc.so.6版本实际上低于 2.32，但是我想保持这种方式，因为在构建这个操作系统映像时，我需要特定的包。
上面链接的答案表明：
也在 sysroot 中构建 libgomp.so.1
但我不清楚该怎么做，也不清楚它是否能解决问题。
如果需要更多信息，请询问，我将编辑问题。谢谢！
