      由于需要使用ROS，因此尝试在树莓派4b的硬件上安装ubuntu系统并使用cs-mipi-imx307模组。
      但实际使用过程中发现该模组提供的两种使用方式（V4L2驱动模式、veye开头的软件包）都仅支持树莓派os。

      尝试重新编译过程中出现以下问题，想问下有没有什么解决办法

      1. cannot find -lbrcmGLESv2 -lbrcmEGL；
        ubuntu下缺少这两个博通的库，通过修改编译文件直接指定使用MESA的库-lGLESv2 -lEGL虽然可以编译通过，但不知是否还是需要在软件源码中做其他修改？
      2. libveyecam.a：error adding symbols: File in wrong format；
        这个文件未开源，实在树莓派os下编译的，因此无法直接参与ubuntu下的代码重编译，想问下有什么解决办法吗？
        我的编译环境：
        系统ubuntu 18.04，镜像链接为https://cdimage.ubuntu.com/releases/18.04/release/ubuntu-18.04.5-preinstalled-server-arm64+raspi4.img.xz
        使用默认编译器gcc

        请尝试一下这个，是在64bit的ubuntu下编译的。

        至于 -lbrcmGLESv2 -lbrcmEGL 这两个库，应该是博通芯片的显示库，是需要硬件支持的。 piOS下有的，是否移植到了ubuntu下建议您上网搜索一下。

        此外，可以尝试v4l2模式进行你的应用。

        可以参考@Viktor 的成功尝试。Thanks him again.

                @veye_xumm 另外可否提供下32bit ubuntu的版本呢（armhf），64bit ubuntu下似乎i2c端口设置的脚本也无法正常工作

                  这个是带fPIC的版本，不过我个人感觉是静态库本身不需要这个选项才对。

                      @veye_xumm 好的非常感谢，这个是编译动态库 用于python代码调用时使用的。就是那个SDK使用方法
