如何构建一个链接到iPhone Simulator SDK的命令行工具？ [英] How do I build a command line tool that links against the iPhone Simulator SDK?

问题描述

为什么我会想这么做？ OpenGL Shader Builder是一款出色的开发工具，但它使用桌面OpenGL编译着色器，它允许ES不支持的一些事情。我想我是否可以创建一个工具来链接到iPhone Simulator SDK中的OpenGLES.framework，我可以得到一些错误报告，而无需构建/安装/运行我的应用程序。

通过检查出现在Xcode构建窗口中的命令行，我得到了这样的结果（在Makefile格式中，为了清楚起见，认真！）：

  ARCH = i386 
 PLATFORM = / Developer / Platforms / iPhoneSimulator.platform / Developer 
 GCC = $（PLATFORM）/usr/bin/gcc-4.2 
 ISYSROOT = $（PLATFORM）/SDKs/iPhoneSimulator3.2.sdk 
 
 glsllint：glsllint.c 
 $（GCC）-arch $（ARCH）-isysroot $（ISYSROOT）-mmacosx-version- min = 10.5 -framework OpenGLES \ 
 glsllint.c -o glsllint 
  

C文件本身很小;它只包含对 glCreateShader（）的调用，以便我可以判断它是否正确链接。上面提供了一个可执行文件，但是当我尝试运行它时：

  dyld：库未加载：/ System / Library / Frameworks /OpenGLES.framework/OpenGLES 
  

这是错误的位置。我该如何做到这一点，所以可执行文件在正确的位置寻找框架？

我知道这不被支持，但该死的，如果它不是很酷工作？要清楚的是，我不希望这个程序绘制任何东西，我只是想加载着色器源代码，使用OpenGL编译它，并打印出错误（如果有的话）。

$ b $现在，问题是，我可以生成一个运行的可执行文件吗？

我没有Mac或iPhone模拟器，所以我不能真正解决问题的这个方面，但是你能链接到不同的OpenGL ES实现的库吗？例如。 OpenTK 或文森特。

这可能不匹配iPhone的100％执行，但可能会让你关闭。

Why the hell would I want to do that? The OpenGL Shader Builder is a great development tool, but it compiles shaders using desktop OpenGL, which allows some things that ES does not. I figure if I can create a tool that links against the OpenGLES.framework in the iPhone Simulator SDK, I can get some error reporting without having to build/install/run my application.

By inspecting the command lines appearing in the Xcode build window, I got as far as this (in Makefile format, for clarity. Seriously!):

ARCH=i386
PLATFORM=/Developer/Platforms/iPhoneSimulator.platform/Developer
GCC=$(PLATFORM)/usr/bin/gcc-4.2
ISYSROOT=$(PLATFORM)/SDKs/iPhoneSimulator3.2.sdk

glsllint: glsllint.c
    $(GCC) -arch $(ARCH) -isysroot $(ISYSROOT) -mmacosx-version-min=10.5 -framework OpenGLES \
    glsllint.c -o glsllint

The C file itself is minimal; it contains only a call to glCreateShader(), so that I can tell if it is linking properly. The above produces an executable, but when I try to run it:

dyld: Library not loaded: /System/Library/Frameworks/OpenGLES.framework/OpenGLES

That's the wrong location. How do I make it so the executable looks for the framework in the correct location?

I know this is not supported, but damn, wouldn't it be cool if it worked? To be clear, I'm not expecting this program to draw anything, I just want to load shader source code, use OpenGL to compile it, and print out the errors, if any.

Right now, the question is, can I produce an executable that runs?

解决方案

I don't have a Mac or an iPhone simulator, so I can't really address that aspect of the question, but can you link to a different OpenGL ES implementation's library? E.g. OpenTK or Vincent.

This may not match 100% the iPhone's implementation, but might get you close.
