我已经为raspberry pi交叉编译了c ++代码。
以下是我遵循的流程
1）从raspberry pi github克隆官方工具链（URL：https://github.com/raspberrypi/tools） 设置arm-linux-gnueabihf-c ++的环境变量（在.bashrc文件中）
3）键入此命令以生成ARM体系结构的二进制文件

4）现在已成功生成二进制文件。我尝试使用以下命令运行二进制文件，但没有运气。
arm-linux-gnueabihf-g++ ./test.cpp -L. -lfoo -o test
即使我在.bashrc文件中设置环境变量但没有运气
分别给出以下错误
LD_PRELOAD=/home/pi/Downloads/linux-sdk-demo-arm/foo.so ./test
LD_LIBRARY_PATH=/home/pi/Downloads/linux-sdk-demo-arm ./test
和
ERROR: ld.so: object './foo.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
./test: error while loading shared libraries: foo.so: cannot open shared object file: No such file or directory
我确定foo.so文件位于正确的路径，但找不到它。这是目录结构，
./test: error while loading shared libraries: foo.so: cannot open shared object file: No such file or directory
