如何爲iOS構建ohNet？

Question

我正在嘗試從openhome.org構建ohNet UPnP堆棧，以便在iPhone和iPhoneSimulator上執行。我曾在網絡上的不同地方看到，iOS上有一個端口，並且實際上在Makefile中有一些對iOS構建的引用。在$ DEVROOT和$ SDKROOT路徑進行一定的編輯後，我可以編譯很多的來源，但生成的錯誤停止：

我不明白爲什麼編譯過程要建立ohNetDll這個平臺，也不知道如何退出該部分/目標。動態庫不支持iOS應用程序，當然也不是Windows本機的dll。

如果您已經在iOS上構建/移植/使用過ohNet，請告知如何操作？我想在ohNet論壇上發佈這個問題，但我無法註冊（因爲我沒有提交安全問題，即使在表單上沒有地方這樣做！）。

源，文檔和API指南都會尋求ohNet非常有前途的，所以我希望你能勸...

「的$ DEVROOT的一些編輯和$ SDKROOT路徑之後，我可以編譯 很多來源...「

對於iPhoneOS平臺，請設置以下環境變量。

export ROOTDIR="/Applications/Xcode.app/Contents/Developer" 
export PLATFORM="iPhoneOS" 
export MAX_VERSION="5.1" 
export DEVROOT=${ROOTDIR}/Platforms/${PLATFORM}.platform/Developer 
export SDKROOT=${DEVROOT}/SDKs/${PLATFORM}${MAX_VERSION}.sdk 

然後，在源的根目錄下，文件「Makefile」文件中，找到以下部分，並確保它看起來相同的，因爲這一個：

ifeq ($(MACHINE), Darwin) 
ifeq ($(mac-arm),1) 
    # Darwin, ARM -> iOS 
    platform ?= iOS 
    linkopts_ohNet =  
    devroot=$(DEVROOT) 
    sdkroot=$(SDKROOT) 
    platform_cflags = -I$(sdkroot)/usr/lib/gcc/arm-apple-darwin10/4.2.1/include/ -I$(sdkroot)/usr/include/ -I/usr/bin/arm-apple-darwin10-gcc -miphoneos-version-min=2.2 -pipe -no-cpp-precomp -isysroot $(sdkroot) -DPLATFORM_MACOSX_GNU -DPLATFORM_IOS -I$(sdkroot)/usr/include/c++/4.2.1/armv6-apple-darwin10/ 
    # It seems a bit weird that iOS uses a sub-dir of Build/Obj/Mac, is that deliberate? --AW 
    osbuilddir = Mac/arm 
    objdir = Build/Obj/Mac/arm/$(build_dir)/ 
    platform_linkflags = -L$(sdkroot)/usr/lib/ -arch armv7 -L$(sdkroot)/usr/lib/system 
    compiler = $(devroot)/usr/bin/llvm-gcc-4.2 -arch armv7 -isysroot $(SDKROOT) -o $(objdir) 
    # No support for linking Shared Objects for ARM MAC 
    # link = $(devroot)/usr/bin/llvm-gcc-4.2 -pthread -Wl $(platform_linkflags) 
    ar = $(devroot)/usr/bin/ar rc $(objdir) 
    native_only = yes 

要點這裏：

1. $ DEVROOT和$ SDKROOT對於您的iOS SDK版本是正確的。
2. 變量$ native_only被設置爲yes。這避免了在Mac主機上嘗試（並且不可避免地失敗）建立ohNetDll時的錯誤和提早退出。

然後，在終端上，在源根目錄（即含有生成文件的一個）類型：

make mac-arm=1 

希望這有助於...
