我按照基本方向（此参考提供了如何处理丢失的库：https : //sourceforge.net/p/gphoto/mailman/message/33367636/）在 Raspberry Pi 上编译最新的 libgphoto2 和 gphoto2，但是当我尝试查看已安装的内容（gphoto2 -v），我得到了这个：
This version of gphoto2 is using the following software versions and options:
gphoto2 2.5.23 gcc, popt(m), no exif, no cdk, no aa, no jpeg, no readline
libgphoto2 2.5.12 all camlibs, gcc, ltdl, EXIF
libgphoto2_port 0.12.0 gcc, ltdl, USB, serial without locking
./configure 和 make 命令可以正常工作。当我执行“sudo make install”时，脚本会继续运行（带有一些重新链接警告），但没有错误。
'sudo make install' 的结尾如下。这可能是什么原因？我不应该看到 libgphoto2 的 2.5.25 吗？
