【问题描述】：
我正在尝试从源代码构建 ROS，在我没有 root 访问权限的环境中，所以没有 sudo apt-get。
rospack 需要libtinyxml-dev，但我不能只安装那个包。因此，我从源代码构建了 TinyXML，并将其安装到 ~/usr/local/{lib, include} 中。一些目标（例如xmlrpcpp、rosbuild）构建良好，但rospack 抛出一个
make[2]: *** No rule to make target '/home/USERNAME/usr/local/lib/libtinyxml.so', needed by
'/home/USERNAME/ros_desktop/catkin_ws/devel/.private/rospack/lib/librospack.so'. Stop.
但是，文件libtinyxml.so 已经存在，并且是指向同样存在的libtinyxml.so.2.6.2 的符号链接。我完全不知道该怎么做。我试过add_library(... SHARED IMPORTED)，一般都在摆弄CMakeLists.txt，但没有骰子。我怎么能告诉 CMake “嘿，这个库存在，只需链接它！”或者，如果错误实际上意味着其他东西，得到更多信息的错误？如果图书馆已经存在，为什么还要make 图书馆？感谢任何可以帮助我的人！

【问题讨论】：
-
请不要描述您的代码，而是将其作为文本添加到您的问题帖子中。
-
Make 没有抱怨
librospack.so。它在抱怨/home/USERNAME/usr/local/lib/libtinyxml.so。那不存在，而且你还没有告诉 make 如何创建它，所以它放弃了。 -
我的意思是“文件
libtinyxml.so，然而，已经存在” -
我还说它“是
libtinyxml.so.2.6.2的符号链接”，很抱歉这个错误，但至少可以推断出来哈哈
