未定義的引用而編譯libgphoto2 /例子

Question

我的問題是有關從https://github.com/gphoto/libgphoto2/tree/master/examples

在gphoto2 libgphoto2我嘗試編譯「libgphoto2 /例子/ lunkwill，佳能的capture.c」（在libgphoto2 /例如基本上所有.c文件顯示相同的錯誤）

GCC -Wall -o TESTOUTPUT -lgphoto2採樣觸發的capture.c（如libgphoto2手動建議）

我得到錯誤

/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'

我做錯了什麼？你錯過了 問候

Answer 1

嘗試此命令

的gcc -o -Wall樣品TESTOUTPUT觸發件的capture.c -lgphoto2 -lgphoto2_port

包括 'gphoto2_port'
