如何建立提升1.56.0升壓::上下文對於iPhone（ARM）

Question

我想建立提升iOS開發，我發現一個自動生成腳本github。 大多數圖書館建立良好，我得到了boost.a。我有測試的asio庫，它的工作原理。

但boost :: coroutine構建失敗，事實上boost :: context構建失敗並出現此錯誤。

darwin.compile.c++ iphone-build/boost/bin.v2/libs/context/build/darwin-8.1~iphone/release/architecture-arm/link-static/macosx-version-iphone-8.1/target-os-iphone/threading-multi/unsupported.o libs/context/src/unsupported.cpp:7:2: error: "platform not supported" #error "platform not supported" ^ 1 error generated.

和升壓::方面的要求說我們應該 指定在bjam的命令行某些附加屬性：目標-OS，ABI，二進制格式，結構和地址模型。 更改腳本的bjam命令行建立從

./bjam -j16 --build-dir=iphone-build -sBOOST_BUILD_USER_CONFIG=$BOOST_SRC/tools/build/example/user-config.jam --stagedir=iphone-build/stage --prefix=$PREFIXDIR toolset=darwin architecture=arm target-os=iphonemacosx-version=iphone-${IPHONE_SDKVERSION} define=_LITTLE_ENDIAN link=static stage > "${LOG}" 2>&1

到

./bjam -j16 --build-dir=iphone-build -sBOOST_BUILD_USER_CONFIG=$BOOST_SRC/tools/build/example/user-config.jam --stagedir=iphone-build/stage --prefix=$PREFIXDIR toolset=darwin abi=aapcs binary-format=mach-o address-model=32 architecture=arm target-os=iphone macosx-version=iphone-${IPHONE_SDKVERSION} define=_LITTLE_ENDIAN link=static stage > "${LOG}" 2>&1

現在的編譯器做正確的事情，但我得到了另一個錯誤

darwin.compile.asm iphone-build/boost/bin.v2/libs/context/build/darwin-8.1~iphone/release/abi-aapcs/address-model-32/architecture-arm/link-static/macosx-version-iphone-8.1/target-os-iphone/threading-multi/asm/jump_arm_aapcs_macho_gas.o libs/context/src/asm/jump_arm_aapcs_macho_gas.S:94:11: error: invalid operand for instruction pop v1 ^

不僅僅是pop v1，以及大量的其他編譯錯誤，並在閱讀鐺的交叉編譯文檔， 我決定將-target arm-macho添加到auto script線213 現在，只有一個錯誤pop v1和8個警告這樣的：

clang: warning: unknown platform, assuming -mfloat-abi=soft clang: warning: argument unused during compilation: '-arch armv7' clang: warning: argument unused during compilation: '-stdlib=libc++' clang: warning: argument unused during compilation: '-arch arm'

我知道一點點的x86 ASM和我讀庫/上下文/ src目錄/ ASM/jump_arm_aapcs_macho_gas.S，似乎那pop v1應該是pop {v1}，我不知道ARM asm，無論如何，我只是想做出這個通過並稍後檢查錯誤。

所以我改變庫/上下文/ src目錄/ ASM/jump_arm_aapcs_macho_gas.S：94 從pop v1到pop {v1}並重新構建這個終於能正常工作。

但只是上下文和協程庫建立好。如libs/atomic/src/lockpool.cpp其他圖書館失敗，錯誤

libs/atomic/src/lockpool.cpp:15:10: fatal error: 'cstddef' file not found

作爲一個虛擬的驢，我出去的技能。

有人可以幫我解答嗎？

我應該鏈接所有引用，但是我的聲望小於10.我不能發佈超過2個鏈接。

我剛剛設法構建Boost.Context（1.59.0），並對來自GitHub的ofxiOSBoost提供的解決方案進行了一些修改。

與針對建築物Boost.Context原溶液中存在的問題是：

1. 構建腳本硬編碼的達爾文工具集來使用「鐺++」，它只能建立純C++代碼，不的彙編代碼
2. 正如您已經想到的那樣，構建腳本提供的b2命令行不包含構建Boost的所有需求。上下文，即：ABI，地址，型號，結構，二進制格式，這些要求是用來匹配「上下文/編譯/ Jamfile.v2」裏面的正確組裝源文件
3. 即使在您正確指定所有的要求，你仍然會得到編譯錯誤，這些錯誤實際上是通過嘗試使用硬編碼的clang ++來編譯程序集源代碼而產生的 - btw，你不應該修改原始程序集源代碼來看它編譯。
4. 裏面上下文/編譯/ Jamfile.v2，你必須建立彙編代碼直列，而不是使用鐺++。幸運的是，相同的文件教你如何建立彙編源代碼內嵌裏面的一些很好的例子，所以最終鐺++只會看到生成的目標文件和工具鏈其餘管道能夠愉快地使用它們。

我貼我在Boost.Context的Jamfile下面所做的修改（你應該足夠聰明弄清楚在哪裏把這些部分）：

actions gasarmv7 
{ 
    cpp -x assembler-with-cpp "$(>)" | as -arch armv7 -o "$(<)" 
} 

actions gasarm64 
{ 
    cpp -x assembler-with-cpp "$(>)" | as -arch arm64 -o "$(<)" 
} 

-

# ARM DARWIN 32_64 
alias asm_context_sources 
    : [ make asm/make_arm_aapcs_macho_gas.o : asm/make_arm_aapcs_macho_gas.S : @gasarmv7 ] 
    [ make asm/jump_arm_aapcs_macho_gas.o : asm/jump_arm_aapcs_macho_gas.S : @gasarmv7 ] 
    [ make asm/make_arm64_aapcs_macho_gas.o : asm/make_arm64_aapcs_macho_gas.S : @gasarm64 ] 
    [ make asm/jump_arm64_aapcs_macho_gas.o : asm/jump_arm64_aapcs_macho_gas.S : @gasarm64 ]

    <address-model>32_64 
    <architecture>arm 
    <binary-format>mach-o 
    <toolset>darwin 
    ; 

下面是對build-libC++的修改sh：

建議使用Boost 1.58.0+，因爲它增加了Boost.Context支持噸arm64

BOOST_V1=1.59.0 
BOOST_V2=1_59_0

} 

要特別注意上面的B2命令行（要求在那裏指定匹配Boost.Context Jamfile.v2變化。

此外，由於原始構建腳本總是嘗試下載和解壓縮存檔，因此您需要將修改保存到某處的Boost.Context Jamfile.v2並重新應用，或者第二次運行（下載，解壓縮，並提供有關修補提升至少一次後）：

再次，請從https://github.com/danoli3/ofxiOSBoost獲得最新版本，並使用升壓1.59.0

希望這有助於！
