我的问题是关于来自https://github.com/gphoto/libgphoto2/tree/master/examples的 gphoto2 中的 libgphoto2
我尝试编译“libgphoto2/examples/lunkwill-canon-capture.c”（基本上 libgphoto2/example 中的所有 .c 文件都显示相同的错误）
gcc -Wall -o TESTOUTPUT -lgphoto2 sample-trigger-capture.c （正如 libgphoto2 手册建议的那样）
我有错误

sample-trigger-capture.c:(.text+0xad): undefined reference to `gp_camera_wait_for_event'

我做错了什么？此致
