c++ - 在PC上编译一个c++程序与DJI phantom 4 pro通信

Question

我正在尝试在我的 PC(linux mint)上接收来自 DJI phantom 4 使用 OpenCV 的摄像头的流。我下面的例子是:https://developer.dji.com/guidance-sdk/documentation/tutorials/index.html (我正在关注 linux 部分)我在/usr/local/lib 中复制了 Copy libDJI_guidance.so 并检查了一下，它就在那里。生成文件是:

#define a compiler
CXX     = g++
#define target name
TARGET  = main
#define dependencies of target 
OBJECTS = main.o DJI_utility.o
#define the Include and Library path
CFLAGS  = -g -Wall -I/usr/local/include -I../../../include
LDFLAGS = -Wl,-rpath,./ -lpthread -lrt -L./ -L/usr/local/lib/ -lDJI_guidance -lusb-1.0 `pkg-config --cflags --libs opencv` 

$(TARGET) : $(OBJECTS)
    $(CXX) -o $(TARGET) $(OBJECTS) $(LDFLAGS)
main.o : main.cpp DJI_utility.h
    $(CXX) $(CFLAGS) -c main.cpp DJI_utility.h
DJI_utility.o : DJI_utility.cpp DJI_utility.h
    $(CXX) $(CFLAGS) -c DJI_utility.cpp DJI_utility.h
clean:
    rm -rf *.o *.gch *.avi $(TARGET)

但是当我在命令行中执行 make 时，我得到:

g++ -o main main.o DJI_utility.o -Wl,-rpath,./ -lpthread -lrt -L./ -L/usr/local/lib/ -lDJI_guidance -lusb-1.0 `pkg-config --cflags --libs opencv` 
/usr/bin/ld: skipping incompatible /usr/local/lib//libDJI_guidance.so when searching for -lDJI_guidance
/usr/bin/ld: skipping incompatible /usr/local/lib/libDJI_guidance.so when searching for -lDJI_guidance
/usr/bin/ld: skipping incompatible //usr/local/lib/libDJI_guidance.so when searching for -lDJI_guidance
/usr/bin/ld: cannot find -lDJI_guidance
/usr/bin/ld: cannot find -lusb-1.0
collect2: error: ld returned 1 exit status
Makefile:12: recipe for target 'main' failed
make: *** [main] Error 1

项目位于:

 ~/Documents/studies_SRT/SRT5/TX_drone/Guidance-SDK/demo/guidance_track

ls 的输出是:DJI_guidance.h DJI_utility.cpp DJI_utility.h DJI_utility.h.gch DJI_utility.o main.cpp main.o Makefile

谢谢。

您似乎下载了错误架构的库文件。如果您使用的是 64 位系统，请下载 64 位版本的库。
