Question

我在将sqlite3合并到我正在编写的程序中时遇到了一些麻烦。在过去的几天里，我一直在寻找解决方案。我正在使用MinGW编译器，并且已经尝试过：

确保C：\ MinGW \ bin目录包含在用户和系统环境中没有空格且用分号分隔的路径变量
使用命令提示符并输入＆＃34; C：\ MinGW \ bin \ gcc shell.c sqlite3.c -lpthread -ldl＆＃34;在所有相关文件的同一目录中返回结果＆＃34; c：/ mingw / bin /../ lib / gcc / mingw32 / 5.3.0 /../../../../ mingw32 / bin / ld.exe：找不到-ldl collect2.exe：错误：ld返回1退出状态＆＃34;
全新安装MinGW和eclipse

如果这对我测试的代码有帮助，我就无法将包含显示为代码，但它们都按顺序排列，iostream，stdio.h和sqlite3 。H 它返回错误＆＃34;致命错误：sqlite3.h：没有这样的文件或目录＆＃34;。我将所有包含文件放在与.cpp源相同的目录中。

int main(int argc, char* argv[])
{
    sqlite3 *db;
    char *zErrMsg = 0;
    int rc;
    rc = sqlite3_open("text.db", &db);
    return 0;
}

Answer 1

#include <stdio.h>
#include "sqlite3.h"

int main(int argc, char* argv[])
{
    sqlite3 *db;
    char *zErrMsg = 0;
    int rc;
    rc = sqlite3_open("text.db", &db);
    return 0;
}

编译和测试结果：

Answer 2

在摆弄了一下后，我意识到我所要做的就是#include“sqlite3.h”与源文件目录中的sqlite.h文件，并在项目树中包含sqlite3.c文件。我正在使用DevC ++，我去了项目＆gt;添加到项目并选择sqlite3.c文件。然后项目＆gt;项目选项＆gt;文件并选择sqlite3.c然后取消选中“将文件编译为C ++”。

编译C和sqlite3
