Raspberry Pi使用SQLite3和SDL2编译多个C ++文件

Question

How would you compile multiple c++ files that are using SDL2 and sqlite3 on a Raspberry Pi 3? If the setup was 6 cpp files being compiled using g++ on a Raspberry Pi 3, and each of those files used the SDL2 library, and 2 used the sqlite3.c and sqlite3.h files, what would the command look like for g++?

I have installed SDL2, SDL2_image, and SDL2_ttf on my Rasberry Pi 3 and I have the sqlite3.c and sqlite3.h files inside of the file with all of the cpp files. I've tried this command:

g++ -std=c++0x Source.cpp Basic_Image.cpp Clock.cpp Text.cpp Widget.cpp TextDatabase.cpp -o Source `sdl2-config --cflags --libs` -LSDL2_image -lSDL2_ttf

and received this error:

/usr/bin/ld: cannot open output file -I/usr/local/include/SDL2: No such file or directory Collect2: error: ld returned 1 exit status.

SDL2 is installed on my Raspberry Pi 3, so why it would throw no such file or directory confuses me.

因此，为了使用预链接的库进行编译，必须在终端中运行以下命令：

$ g++ -std=c++0x Source.cpp Basic_Image.cpp CLock.cpp Text.cpp Widget.cpp TextDatabase.cpp -o Source $(pkg-config --libs --cflags sdl2 SDL2_image SDL2_ttf sqlite3)
