编译libgphoto2时未定义引用/示例

Question

我的问题是关于https://github.com/gphoto/libgphoto2/tree/master/examples在gphoto2中的libgphoto2

我尝试编译示例(基本上libgphoto2/ "libgphoto2/examples/lunkwill-canon-capture.c“中的所有.c文件都显示相同的错误)

gcc触发器测试样本-lgphoto2 - -Wall -capture.c(如libgphoto2手册所示)

我弄错了

/tmp/ccg65O2b.o: In function `wait_event_and_download':
sample-trigger-capture.c:(.text+0xad): undefined reference to `gp_camera_wait_for_event'
sample-trigger-capture.c:(.text+0x371): undefined reference to `gp_camera_file_read'
sample-trigger-capture.c:(.text+0x57b): undefined reference to `gp_camera_file_delete'
/tmp/ccg65O2b.o: In function `main':
sample-trigger-capture.c:(.text+0x607): undefined reference to `sample_create_context'
sample-trigger-capture.c:(.text+0x64c): undefined reference to `gp_log_add_func'
sample-trigger-capture.c:(.text+0x658): undefined reference to `gp_camera_new'
sample-trigger-capture.c:(.text+0x66b): undefined reference to `gp_camera_init'
sample-trigger-capture.c:(.text+0x6db): undefined reference to `gp_camera_trigger_capture'
sample-trigger-capture.c:(.text+0x799): undefined reference to `gp_camera_exit'
collect2: error: ld returned 1 exit status

我做错什么了？诚挚的问候

正在尝试此命令

gcc触发器测试示例-Wall - -o -capture.c -lgphoto2 -lgphoto2_port

您错过了包含“gphoto2_port”
