在文件libCorePlot-CocoaTouch.a中缺少必需的体系结构x86_64 [英] missing required architecture x86_64 in file libCorePlot-CocoaTouch.a

问题描述

根据 Ray Wenderlich教程，我完成了以下操作：

According to the Ray Wenderlich tutorial, I done the following :

第1步 - 我已下载 < a href =http://code.google.com/p/core-plot/downloads/detail?name=CorePlot_1.4.zip&can=2&q=> CorePlot_1.4.zip 在官方网站上

Step 1 - I downloaded CorePlot_1.4.zip on the official website

第2步 - 我在项目中添加了 CorePlotHeaders文件夹和名为libCorePlot-CocoaTouch.a 的静态库（检查将项目复制到目标组的文件夹（如果需要））

Step 2 - I added to my project the CorePlotHeaders folder and the static library named libCorePlot-CocoaTouch.a (checking "Copy items into destination group’s folder (if needed)")

第3步 - 我在其他链接标记字段中添加了以下内容： -ObjC

Step 3 - I added into Other Linker Flags field the following : -ObjC

第4步 - 我检查了链接二进制文件库如果 libCorePlot-CocoaTouch.a 和 QuartzC这里有

Step 4 - I checked into Link Binary with Libraries if libCorePlot-CocoaTouch.a and QuartzCore frameworks were here

结果： 当我编译项目时，我工作正常使用 Iphone Retina（4英寸）。但当我使用 Iphone Retina（4英寸64位）
时，我尝试构建并运行时收到以下消息：

Result : When I compile my project, it works fine when I'm using Iphone Retina (4-Inch). But when I'm using Iphone Retina (4-Inch 64-bit) I got the following message when I try to build and run :

ld：警告：忽略文件/blah/blah/libCorePlot-CocoaTouch.a，缺少文件/blah/blah/libCorePlot-CocoaTouch.a中需要的架构x86_64（3个切片）

这里有完整的消息：

Here the complete message :

我在这个问题上花了几个小时......请帮忙......

I spent several hours on this issue... Please help...

推荐答案

如果你想要一个64位版本的Core Plot，你将不得不构建一个新版本的静态库。 Arm64版本需要iOS 7，但Core Plot也支持早期版本，因此预构建的库仅为32位。

If you want a 64-bit version of Core Plot, you'll have to build a new version of the static library. Arm64 builds require iOS 7 but Core Plot supports earlier versions, too, so the pre-built library is 32-bit only.

打开 CorePlot- CocoaTouch.xcodeproj 并将体系结构设置更改为标准体系结构（包括64位）。构建通用库目标并包含生成的静态库来代替Core Plot 1.4附带的静态库，或者使用依赖项目设置。

Open CorePlot-CocoaTouch.xcodeproj and change the architecture settings to "Standard Architectures (including 64-bit)". Either build the "Universal Library" target and include the resulting static library in place of the one included with Core Plot 1.4 or use the dependent project setup instead.
