使用Eclipse进行C编程(库之谜)
使用Eclipse进行C编程(库之谜)
提问于 2009-06-12 13:25:58
当我将一个库连接到我的程序时，Eclipse不会生成任何可执行文件，我只得到一个对象文件。当我从我的程序中断开库(删除所有路径和库函数)时，我得到一个可执行文件。
但是，在第一种情况下，我没有得到任何错误。
哪里出了问题？
我的工作环境: Linux、C、Eclipse。

查看日志/构建输出。链接器找不到您想要的库，因此编译在对象生成时停止。
关于以下内容的编辑：
collect2: ld returned 1 exit status链接器出现故障
我猜..。未链接OpenCV
您的程序似乎也使用OpenCV。您需要将可执行文件链接到openCV，以便解析库libWISE_C.so中的符号。可以通过eclipse添加依赖项，也可以手动添加。请记住，您需要包含opencv头文件、通过"-L“包含库路径以及链接库二进制文件。
在Eclipse中，右键单击您的项目并转到Properties。接下来，打开“GCC C++链接器”下的“库”部分。在“库(-l)”面板中，添加一个具有opencv值的条目，然后单击“确定”。

看起来libWISE_C.so使用的是OpenCV或类似的库。您必须在链接行上为可执行文件提供另一个库，否则将无法获得成功的链接。
既然您自己构建了libWISE_C.so，那么您应该知道所有未定义的符号应该来自哪个其他库。
您还可以将这个“其他库”添加到libWISE_C.so本身的链接行中，从而使libWISE_C.so客户端不必这么做。
