Gcc Yocto mfloat abi配置

当我编译yocto项目时，我遇到了以下错误

当我使用readelf命令分析libGLESv2.so库时，我得到以下输出

据我所知，只有OpenGL库被编译为硬浮点。所有其他库都编译为软浮点。所以我得到了上面提到的错误。

我能为这个问题做些什么？为什么只有OpenGL库被编译为硬浮点？

您使用的是哪个版本/版本的poky？哪个

bitbake

命令导致错误？您是否使用了其他图层？您是否尝试过运行

cleanall

并重新构建它？我使用的是Yocto Jethro 2.0版本，是的，我使用的是meta-qt5、meta-oe、meta-ruby和meta-sunxi层。我没有尝试运行cleanall。您是否检查过其他层也在同一版本（jethro）上？是否有

cleanall

帮助？是的，我检查了。我尝试了cleanall，但结果是sameCan如果您检查您的机器配置文件（针对您的目标平台），DEFAULTTUNE的值是多少？
