Не удается найти ошибку компилятора -lsqlite3 c
to use sqlite3 in your C++ / C source code you should download
the amalgamation C source file at "https://www.sqlite.org/download.html"
then extract the source files in your source folder.
Then in your code you include sqlite3 with :
#include "sqlite3.h"
and finaly you compile your program with :
gcc yourSourceFile.cpp sqlite3.c -o yourExeFile.exe
