Compiling custom SQLite for an iPhone app
提问by John Biesnecker
I'm trying to compile the SQLite amalgamationsource 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.
我正在尝试将SQLite 合并源编译到我的 iPhone 应用程序中（以使我能够访问在 iPhone 编译版本的二进制文件中不可用的全文搜索功能。
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.
当我将 sqlite3.c 和 sqlite3.h 添加到普通的 Carbon C 应用程序模板时，它编译得很好（有一个关于未使用变量的警告），但是当我尝试在我的 iPhone 项目中编译它时，我得到了一些相关的错误缺少函数声明。我可以通过显式包含 ctype.h 来解决这些问题，但这有点奇怪。
However, even after it builds it fails on linking with the following error:
但是，即使在它构建之后，它也无法链接并出现以下错误：
"_sqlite3_version", referenced from:
_sqlite3_version$non_lazy_ptr in sqlite3.0
symbol(s) not found
collect2: ld returned 1 exit status
I assume that it's something in the iPhone app's build settings, but I can't figure it out. Any ideas?
我认为这是 iPhone 应用程序的构建设置中的某些内容，但我无法弄清楚。有任何想法吗？

Try it with this steps:
请按照以下步骤尝试：
- xcode menu -> project -> new target -> static library -> target name: SQLite
- drop SQLite amalgamation source into the project, now you can select the target, choose SQLite
- xcode menu -> project -> edit active target -> tab General -> Direct Dependencies -> add SQLite
- tab General -> Linked Libraries -> add your SQLite
- xcode 菜单 -> 项目 -> 新建目标 -> 静态库 -> 目标名称：SQLite
- 将 SQLite 合并源放到项目中，现在可以选择目标，选择 SQLite
- xcode 菜单 -> 项目 -> 编辑活动目标 -> 选项卡 General -> Direct Dependencies -> 添加 SQLite
- 选项卡 General -> Linked Libraries -> 添加你的 SQLite

I've managed to do this using the amalgamation and dumped it straight into my project without having to do the linking catlan suggested (I'm not saying it's a bad idea, merely it's possible to do in the main project).
我已经使用合并成功地做到了这一点，并将其直接转储到我的项目中，而无需执行 catlan 建议的链接（我并不是说这是一个坏主意，只是可以在主项目中进行）。
I didn't need to edit anything (except for adding the necessary FTS define for the text searching) and compiled error free. Check your build settings and ensure '-sqlite3' isn't in your Other Linking Flags.
我不需要编辑任何东西（除了为文本搜索添加必要的 FTS 定义）并且编译没有错误。检查您的构建设置并确保“-sqlite3”不在您的其他链接标志中。

That type of error usually means a missing framework.
这种类型的错误通常意味着缺少框架。
- Right- or control-click on your Project's Frameworksfolder.
- Select Add > Existing Framework...
- Go to: Macintosh HD > Developer > Platforms > iPhoneOS.platform > Developer > SDKs > iPhoneOS2.2sdk > usr > liband select libsqlite3.dylib
- Rebuild your project
- 右键或按住 Control 单击项目的Frameworks文件夹。
- 选择添加 > 现有框架...
- 转到：Macintosh HD > Developer > Platforms > iPhoneOS.platform > Developer > SDKs > iPhoneOS2.2sdk > usr > lib并选择libsqlite3.dylib
- 重建你的项目
That should take care of it, I think. You may need to add a similar library for running on the iPhone Simulator.
我想，那应该照顾它。您可能需要添加一个类似的库以在 iPhone 模拟器上运行。
