为什么 arm-poky-linux-gnueabi-ar 说“无效选项 -- 'g'”而这个选项没有出现在命令行的 args 列表中？

问题描述

我正在使用 bitbake 构建命令“bitbake -v update-engine-titan-c”，这里是日志：

我不明白为什么 arm-poky-linux-gnueabi-ar 说 "invalid option -- 'g'" 而这个选项没有出现在命令的 arm-poky-linux-gnueabi-ar args 列表中行（见日志）？

解决方法

似乎 ar 不接受 -lgio-2.0 参数。我认为您应该将 libgio-2.0.so 文件的路径直接放在命令行上，而不是通过 -l 参数。

（在 ar 联机帮助页中，它说 -l 参数被接受但被忽略，所以我怀疑 GM 在评论中说 -lgio-2.0 是 {{1} } 来自)
