arm-linux-gnueabihf-g++ arm-linux-gnueabihf/bin/ld.exe: cann

Question

我尝试在Windows下用arm-linux-gnueabihf-g++交叉编译树莓。我成功地尝试了一个"Hello Word"示例，但当我尝试使用挂架库"libpylonbase.so"时，
编译似乎还可以，但链接器告诉我它找不到"libpylon base.so"。我已经用-L添加了库的绝对路径，但它不起作用。为什么我说它找不到图书馆？以下是命令和结果：

所以我试着让Dir知道这条路，图书馆就在这里。那我为什么找不到呢？

事实上，为了正确链接此库，我删除了"lib"前缀：要链接">libpylonbase.so"，指令为">-lpylonbase。我希望它对很多人有用。。。
