missing required architecture i386 in file

问题描述：今天研究QCAR的iPhone版本，下载Demo后编译报错，如下：

ld: warning: ignoring file ../../build/lib/arm/libQCAR.a, missing required architecture i386 in file

ld: symbol(s) not found for architecture i386

clang: error: linker command failed with exit code 1 (use -v to see invocation)

问题分析：开始以为是没有找到库，重新引用库，无效。后查Google，要删除掉Targets-Build Settings-Library Search Paths，照做，无效。最后找到以下这段：

It seems the library is built for phone deployment (ARM) but you are trying to link it to a simulator executable (x86). This won't work. Rebuild the library for the simulator.

问题解决：切换成Device编译，搞定。

升级后iOS后上传审核Architectures问题

问题描述：今天Geely的iPhone版本要上架，用Application Loader上传报错，如下：

iPhone/iPod Touch: application executable is missing a required architecture. At least one of the following architecture(s) must be present: armv6

问题分析：显然问题出在升级iOS5后的配置问题上。

问题解决：在Target的Build Settings里，找到Architectures，点击"Standard(armv7)"，再点"Other..."，把原来的内容删掉，在分两行输入"armv6"和"armv7"，搞定。

iOS5结构体编译严格

问题描述：今天二罗升级iOS SDK5，发现Monster不能编译了。具体报错信息如下：

variable length array of non-POD element type 'b2Vec2'

问题分析：错误指向的是cocos2d里一个结构体数组定义，如下：

b2Vec2 vertices[vertexCount];

问题解决：把其改成指针形式，如下：

b2Vec2 *vertices = new b2Vec2[vertexCount];

搞定了。

iOS SDK5升级类库问题

问题描述：今天小新升级iOS SDK5，发现Stupid不能编译了。具体报错信息如下：

ld: library not found for -lz.1.2.3
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/clang failed with exit code 1

问题分析：看来是找不到类库的问题，lz.1.2.3对应的是libz.1.2.3.dylib。而/Developer/Platforms/iPhoneOS.platform/DeviceSupport/Latest/Symbols/usr/lib目录下只有libz.1.2.5.dylib。

问题解决：在project设置里重新引到新版本的类库，一切ok了。
