为什么 XCode 4 在构建过程中找不到我的 .h 文件? [英] Why can't XCode 4 find my .h files during a build?
问题描述
我有一个无法构建的项目，因为编译器 (?) 似乎找不到 .h 文件.我尝试使用完整路径、相对路径并设置项目搜索路径(标题和用户标题)，但似乎没有任何效果.我觉得很奇怪的是，即使使用完整路径，它也会出错:没有这样的文件或目录(该文件确实存在于指定的路径中).
I have a project that won't build because the compiler (?) can't seem to find the .h files. I have tried using the full path, relative path and setting the Project Search Paths (both Header and User Header) and nothing seems to work. What I find very strange is even with the full path it gives an error: No such file or directory (the file does indeed exist in the specified path).
有人可以就可能出现的问题提出一些建议吗?我当然会很感激.
Can anybody give some suggestions on what could be the problem? I would certainly appreciate it.
导入语句:
#import <Foundation/Foundation.h>
#import <zxing/common/Counted.h>
#import <zxing/Result.h>
#import <zxing/BinaryBitmap.h>
#import <zxing/Reader.h>
#import <zxing/ResultPointCallback.h>
标题位于:
/Users/rolfmarsh/iPhoneCodeLibrary/BarcodeLibrary/zxing-1.6/cpp/core/src/zxing
标题搜索路径为:
$(inherited)
"$(SRCROOT)/zxing/common"
和
/Users/rolfmarsh/iPhoneCodeLibrary/BarcodeLibrary/zxing-1.6/cpp/core/src
包含文件的完整路径:
/Users/rolfmarsh/iPhoneCodeLibrary/BarcodeLibrary/zxing-1.6/cpp/core/src/zxing/Result.h
推荐答案
我发布此内容是为了让像我这样在项目中集成 zxing qr 阅读器的新手更简单，并关闭几个相关的线程到zxing整合.
I am posting this in order to make things simple for newbies like me that are integrating zxing qr reader in their projects and to bring closure to a couple of threads related to zxing integration.
1.主要事情 - 绝对确保您拥有最新版本.
1. Main thing - Be absolutely sure you have the latest version.
http://zxing.googlecode.com/svn/trunk/
[现在，即 1 月 18 日，您将不会再遇到 zxing/common/文件夹的问题.最简单的解决方法:获取最新代码！]
[By now, January 18th, you will have no more issues with that zxing/common/ folder. Easiest fix for this: get the latest code!]
2.转到 zxing -> iphone -> ZXingWidget.
2. Go to zxing -> iphone -> ZXingWidget.
将 ZXingWidget.xcodeproj 文件拖放到 Xcode 项目的组和文件"侧栏的根目录上.
Drag ZXingWidget.xcodeproj file and drop it onto the root of your Xcode project's "Groups and Files" sidebar.
[您现在应该在那里列出 ZXingWidget.xcodeproj，它必须下拉并列出其内容]
[you should now have ZXingWidget.xcodeproj listed there and it has to drop down and list it's content]
3.在同一个地方，项目导航器，选择:
3. In the same place, project navigator, select:
您的项目文件 -> 目标 -> '您的项目名称' -> 构建阶段 -> 将二进制文件与库链接.
Your project file - > Targets -> 'your project name' -> Build phases -> Link binary with libraries.
您应该找到一个名为工作区"的文件夹.从内部添加libZXingWidget.a".
You should find a folder named 'Workspace'. Add 'libZXingWidget.a' from within.
4.仍处于构建阶段，展开目标依赖项并添加 ZXingWidget.
4. Still in Build phases, expand Target Dependencies and add ZXingWidget.
5.选择 Build Settings 并搜索 Header Search Paths.您需要向标题搜索路径添加 2 条记录.您不需要将值与用户标题搜索路径相关联.您可以通过双击右侧的列来实现此目的.将出现一个小的弹出窗口.使用 + 按钮添加第一条记录.添加:
5. Select Build Settings and search for Header Search Paths. You need to add 2 records to Header Search Paths. You do not need to associate values to User Header Search Paths. You achieve this by double clicking the column on the right. A small popover window will apear. Use the + button to add the first record. Add:
../zxing/iphone/ZXingWidget/Classes
../zxing/iphone/ZXingWidget/Classes
现在使用 + 按钮添加第二条记录.添加:
Now use the + button to add the second record. Add:
../zxing/cpp/core/src
../zxing/cpp/core/src
这些是我使用的值.这些值有效是因为我使用相同的文件夹来托管我的项目和 zxing 文件夹.
These are the values I use. These values work because I use the same folder to host both my project and the zxing folder.
[如果您决定使用不同的文件结构，请务必正确引用您的文件夹.]
[Be sure to refer your folder properly in case you decide to have a different file structure.]
6.返回到 Build Phases 并添加以下所需的 ios 框架:
6. Go back to Build Phases and add the following ios frameworks required:
AVFoundation
AVFoundation
音频工具箱
核心视频
核心媒体
libiconv
通讯录
地址簿界面
7.
创建一组文件 (.h&.m) 并将其 .m 扩展名更改为 .mm
Create a set of files (.h&.m) and change it's .m extension to .mm
8.通过在先前创建的文件中包含以下内容来测试集成:
8. Test the integration by including the following in the file previously created:
#import <ZXingWidgetController.h>
#import <QRCodeReader.h>
此时，只有当您运行的不是最新版本时，才会遇到丢失的文件.希望这会有所帮助.
At this point you should run into missing files only if you are not running the latest version. Hope this helps.
