/src/DB/sqlite3.dll：无法识别文件：无法识别文件格式

Question

I am trying to include a sqlite3 in my cpp project but while compilation it gives below error:

g++ -c -std=c++11 -g src/Main.cpp -I"C:/Mycode/src/DB" -L"C:/Mycode/src/DB" -lsqlite3

g++ -g -o Main.exe Main.o Data.o SqliteApi.o -lws2_32 -L"C:/Mycode/src/DB" -lsqlite3

C:/Mycode/src/DB/sqlite3.dll: file not recognized: File format not recognized

collect2.exe: error: ld returned 1 exit status

make: ***[Mycode.exe] Error 1

I feel during final linking time it gives error. I am using my own make file for compilation, below is the make command I am using:

DB_DIR="C:/Mycode/src/DB"

clean:
    rm Main.o Main.exe

Main.exe: Main.o Data.o SqliteApi.o 
    g++ -g -o Main.exe Main.o Data.o SqliteApi.o -lws2_32 -L${DB_DIR} -lsqlite3 

Main.o: src/Main.cpp
    g++ -c -std=c++11 -g src/Main.cpp -I${DB_DIR} -lsqlite3

Data.o: src/Data.cpp
    g++ -c -std=c++11 -g src/Data.cpp

SqliteApi.o: src/SqliteApi.cpp
    g++ -c -std=c++11 -g src/SqliteApi.cpp

I have googled but I couldn't find any solution or suggestion for this error. Any help will be much appreciated.

The recommended way of using the SQLite library is to compile the amalgamation source file directly into your program:

Main.exe: Main.o Data.o SqliteApi.o 
    g++ -g -o Main.exe Main.o Data.o SqliteApi.o sqlite3.o -lws2_32

sqlite3.o: src/sqlite3.c
    gcc -c ... src/sqlite3.c
