iPhone模擬器的編譯錯誤

Question

我正在嘗試為iphone模擬器編譯一些代碼，但出現此錯誤：

    /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 -O3 -isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk -Os  -O3 -isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk -Os -x objective-c -I../../include  -c version.c      
    In file included from /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/Security.framework/Headers/Security.h:29,
                     from /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSURLCredential.h:14,
                     from /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/Foundation.framework/Headers/Foundation.h:80,
                     from version.c:11:
    /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/Security.framework/Headers/SecKey.h:166: error: expected declaration specifiers or ‘...’ before ‘SecPadding’
    /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/Security.framework/Headers/SecKey.h:196: error: expected declaration specifiers or ‘...’ before ‘SecPadding’
    /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/Security.framework/Headers/SecKey.h:228: error: expected declaration specifiers or ‘...’ before ‘SecPadding’
    /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/Security.framework/Headers/SecKey.h:257: error: expected declaration specifiers or ‘...’ before ‘SecPadding’
    make: *** [version.o] Error 1

但是，如果我為實際的iphone進行編譯，則可以正常工作：

    /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 -O3 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk  -arch armv6  -Os  -O3 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk  -arch armv6  -Os -x objective-c -I../../include  -c version.c      

僅包含Foundation.h而不包含其他代碼的文件就會發生此問題：

#import <Foundation/Foundation.h>

關於這有什么想法嗎？ 奇怪的是，我希望這對於iPhone和模擬器都失敗。

編輯：fyi，我不使用XCode。 這是一個使用Makefile的大型多平台項目。 您在上面看到的命令是從Makefile發出的。

Answer 1

我看到了同樣的事情。 解決方法是添加-miphoneos-version-min = 3.0編譯器指令。

Answer 2

僅當您將SDK 3.0與iphone模擬器一起使用時，才會發生此問題。 使用SDK 2.0（帶有gcc 4.0）將進行編譯。 這似乎是XCode默認使用的。

非常奇怪的是，此問題僅適用於模擬器，而不適用於iPhone本身。 同樣奇怪的是，gcc4.2無法與模擬器sdk 2.0一起編譯-您必須使用gcc4.0。

出於好奇，我編寫了一個makefile來演示該問題：

IPHONE_GCC_VER    = 4.0
IPHONE_SDK_VER    = 3.0
IPHONE_DEV_PATH   = /Developer/Platforms/iPhoneOS.platform/Developer
IPHONE_SDK        = $(IPHONE_DEV_PATH)/SDKs/iPhoneOS$(IPHONE_SDK_VER).sdk 
IPHONE_GCC        = $(IPHONE_DEV_PATH)/usr/bin/gcc-$(IPHONE_GCC_VER)

SIMULATOR_GCC_VER = 4.0
SIMULATOR_SDK_VER = 2.0
SIMULATOR_DEV_PATH= /Developer/Platforms/iPhoneSimulator.platform/Developer
SIMULATOR_SDK     = $(SIMULATOR_DEV_PATH)/SDKs/iPhoneSimulator$(SIMULATOR_SDK_VER).sdk
SIMULATOR_GCC     = $(SIMULATOR_DEV_PATH)/usr/bin/gcc-$(SIMULATOR_GCC_VER)

TEST_FILE=/tmp/test.m

all: info make-test-file
    $(IPHONE_GCC)    -isysroot $(IPHONE_SDK)    -arch armv6 -c $(TEST_FILE) 
    $(SIMULATOR_GCC) -isysroot $(SIMULATOR_SDK) -arch i386  -c $(TEST_FILE) 

info:
    @echo "iphone gcc   : $(IPHONE_GCC_VER)"
    @echo "iphone sdk   : $(IPHONE_SDK_VER)"
    @echo "simulator gcc: $(SIMULATOR_GCC_VER)"
    @echo "simulator sdk: $(SIMULATOR_SDK_VER)"
    @echo ""

make-test-file:
    echo "#import <Foundation/Foundation.h>" > $(TEST_FILE)

默認值是可以使用的默認值，但是您可以在命令行上覆蓋它們。 例如：

$ make -f Makefile.iphone-error-demo SIMULATOR_SDK_VER=3.0 SIMULATOR_GCC_VER=4.0
iphone gcc   : 4.0
iphone sdk   : 3.0
simulator gcc: 4.0
simulator sdk: 3.0

Answer 3

您確定兩個項目之間的設置相同嗎？ 我敢打賭，您不小心更改了一些模擬器設置。

Answer 4

右鍵單擊框架，然后單擊獲取信息。 在“信息”對話框中查看路徑。 它應該簡短，例如“ System / Library / Frameworks /”

如果不是，請使用“選擇”按鈕在當前SDK文件夾下找到框架。

另外，請確保僅在路徑下方看到選擇的“相對於當前SDK”選項。

Answer 5

在將框架添加到項目中時，當詢問是否要將框架復制到項目文件夾中時，是否將復選框設置為“是”。 如果是這樣，則應將復選框設置為“否”。

如果您創建一個新項目並嘗試在不添加任何內容的情況下運行，是否也會發生這種情況，因為您可能不小心更改了該項目中的編譯標志

Answer 6

應該通過將其添加到編譯器選項中來解決此問題：

-D__IPHONE_OS_VERSION_MIN_REQUIRED=30000

Answer 7

將項目從sdk 3.2更改為4.1時，我遇到了此問題。 原來，解決方案是將項目的構建設置中的iOS部署目標從2.0更改為3.0 。

右鍵單擊xcode中的項目（如果正在使用），在構建窗格中，單擊iOS部署目標-> 3.0。
