c++ - xcode c++ sqlite3 symbol(s) not found for architecture x86_64

Question

你好，我想在 xcode 4 的 c++ 项目中使用 sqlite

现在我收到这个错误

Ld /Users/jayb/Library/Developer/Xcode/DerivedData/EMS-bpigynlzjbrescadebhoiupqmtkg/Build/Products/Debug/EMS normal x86_64 cd /Users/jayb/Documents/Developement/EMS/EMS setenv MACOSX_DEPLOYMENT_TARGET 10.8 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++ -arch x86_64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk -L/Users/jayb/Library/Developer/Xcode/DerivedData/EMS-bpigynlzjbrescadebhoiupqmtkg/Build/Products/Debug -F/Users/jayb/Library/Developer/Xcode/DerivedData/EMS-bpigynlzjbrescadebhoiupqmtkg/Build/Products/Debug -filelist /Users/jayb/Library/Developer/Xcode/DerivedData/EMS-bpigynlzjbrescadebhoiupqmtkg/Build/Intermediates/EMS.build/Debug/EMS.build/Objects-normal/x86_64/EMS.LinkFileList -mmacosx-version-min=10.8 -o /Users/jayb/Library/Developer/Xcode/DerivedData/EMS-bpigynlzjbrescadebhoiupqmtkg/Build/Products/Debug/EMS

我发现这是链接器问题它可以通过编译器选项 -lsqlite3 修复

但是，我如何在 Xcode 中添加该选项？？？？？

我在 xcode 4.4 上使用“运行”按钮来编译我的项目。我没有在终端窗口中编译。

这是我的代码

#include <iostream>
#include <stdlib.h>
#include <stdio.h>
#include <sqlite3.h>

using namespace std;

int main()
{   
    sqlite3 *db;
    int rc = sqlite3_open("EMSDB", &db);
    if (rc) {
        fprintf(stderr, "Can't open database: %s\n", sqlite3_errmsg(db));
        exit(0);
    }
    else {
        fprintf(stderr, "Opened Database successfully\n");
    }

    sqlite3_close(db);

    return 0;
}

我找到了路，希望它能帮助寻找相同解决方案的人。现在它构建正确，我可以看到输出

糟糕，我还不能发布图片:(

从 xcode build设置，您可以找到一个名为(链接)的选项卡并在“链接”选项卡上有字段调用“其他链接器标志”我只是为调试和发布添加了 -lsqlite3

干杯
