无法在 Raspberry pi 4 上为 SAP 安装 Python 的 Pyrfc 库

Question

想在 raspberry pi 4 上安装 pyrfc 但由于安装错误无法安装

我已经完成了pyrfc文档中提到的所有步骤 但是我无法在我的树莓派上安装它。 我正在使用 python 3.9.2

下面是我在运行 pip install pyrfc 后得到的错误日志。 请帮助

这个错误信息

arm-linux-gnueabihf-gcc：错误：无法识别的命令行选项

-minline-all-stringops

arm-linux-gnueabihf-gcc 是 32 位
