为iPhone应用程序编译自定义SQLite [英] Compiling custom SQLite for an iPhone app

问题描述

我正在尝试将 SQLite合并来源编译到我的iPhone应用中（给我访问iPhone编译版本的二进制文件中没有的全文搜索功能。

I'm trying to compile the SQLite amalgamation source into my iPhone app (to give me access to the full-text searching functionality that isn't available in the iPhone-compiled version of the binary.

当我添加sqlite3.c和sqlite3.h时正常的Carbon C应用程序模板，它编译得很好（只有一个关于未使用的变量的警告），但是当我尝试在我的iPhone项目中编译它时，我得到了许多与缺少函数声明有关的错误。我能够解决这些问题。显式包含ctype.h的问题，但是有点奇怪。

When I add sqlite3.c and sqlite3.h to a normal Carbon C app template, it compiles just fine (with a single warning about an unused variable), but when I try compiling it in my iPhone project I get a number of errors relating to missing function declarations. I'm able to solve these problems by explicitly including ctype.h, but it's a little strange.

然而，即使在构建之后，它也会因链接失败而出现以下错误：

However, even after it builds it fails on linking with the following error:

"_sqlite3_version", referenced from:
_sqlite3_version$non_lazy_ptr in sqlite3.0
symbol(s) not found
collect2: ld returned 1 exit status

我认为它是iPho中的东西ne app的构建设置，但我无法弄清楚。有什么想法？

I assume that it's something in the iPhone app's build settings, but I can't figure it out. Any ideas?

推荐答案

尝试按照以下步骤操作：

Try it with this steps:

1. xcode菜单 - >项目 - >新目标 - >静态库 - >目标名称：SQLite


2. 将SQLite合并源放入项目中，现在可以选择目标，选择SQLite


3. xcode菜单 - >项目 - >编辑活动目标 - >选项卡常规 - >直接依赖关系 - >添加SQLite


4. 选项卡常规 - >链接库 - >添加您的SQLite

1. xcode menu -> project -> new target -> static library -> target name: SQLite
2. drop SQLite amalgamation source into the project, now you can select the target, choose SQLite
3. xcode menu -> project -> edit active target -> tab General -> Direct Dependencies -> add SQLite
4. tab General -> Linked Libraries -> add your SQLite
