-ngiphoneos-version-min = .sd中的clang错误无效版本号 [英] clang error invalid version number in -miphoneos-version-min=.sd

问题描述

当我为ios编译 librtmp 时，脚本显示如下：

 ＃！/ bin / sh 
 
＃OS X Yosemite，Xcode 6.1 
 
 set -ex 
 
 DEVELOPER =/ Applications / Xcode。 app / Contents / Developer
 DEVICE_SDK =$ DEVELOPER / Platforms / iPhoneOS.platform / Developer / SDKs / iPhoneOS.sdk
 SIMULATOR_SDK =$ DEVELOPER / Platforms / iPhoneSimulator.platform / Developer / SDKs / iPhoneSimulator.sdk
 CURRPATH =`pwd` 
 SOURCE =rtmpdump
 DSTDIR =librtmp
 LIBSSL =`cd ../ OpenSSL / libssl; pwd` 
 ARCHS =i386 x86_64 armv7 armv7s arm64
 
 rm -rf $ DSTDIR 
 mkdir $ DSTDIR 
 
 if [！ -d $ SOURCE];然后
 git clone git：//git.ffmpeg.org/rtmpdump $ SOURCE 
 else 
 cd $ SOURCE 
 git fetch 
 cd .. 
 fi 
 
 cd $ SOURCE / librtmp 
 
用于ARCH中$ ARCHS; do 
 mkdir -p ../$DSTDIR/$ARCH 
 
 if [[$ ARCH == arm *]];那么
 SDK = $ DEVICE_SDK 
 else 
 SDK = $ SIMULATOR_SDK 
 fi 
 
 perl -i -pe'| ^ AR = \ $ \\ \\（CROSS_COMPILE \）ar | AR = xcrun ar |'Makefile 
 $ b CROSS_COMPILE =$ DEVELOPER / usr / bin /\ 
 XCFLAGS = -  O0 -isysroot $ SDK  - I $ LIBSSL / include -arch $ ARCH\ 
 XLDFLAGS = -  isysroot $ SDK -L $ LIBSSL / lib -arch $ ARCH -miphoneos-version-min = 7.0\ 
 make SYS = darwin 
 make SYS = darwin prefix =$ CURRPATH / $ DSTDIR / $ ARCHinstall 
 make clean 
完成
 
 
 mkdir -p $ $ LIBS中的LIB的CURRPATH / $ DSTDIR / lib 
 cd $ CURRPATH / $ DSTDIR / $ ARCH / lib 
 LIBS =`ls * .a` 
 cd $ CURRPATH 
; do 
 lipo -create`find $ DSTDIR -name $ LIB` -output $ DSTDIR / lib / $ LIB 
完成
 
 cp -rf $ DSTDIR / $ ARCH / include $ DSTDIR 
 
用于ARCH中$ ARCHS;做
 rm -rf $ DSTDIR / $ ARCH 
完成
  

when statement make SYS = darwin 运行，错误显示：

  / Applications / Xcode。 app / Contents / Developer / usr / bin / gcc -Wall -O0 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk -I / Users / Smeegol / Desktop / AVCodecs2 / OpenSSL / libssl / include -arch armv7 -DRTMPDUMP_VERSION = \v2.4\-DUSE_OPENSSL -O2 -fPIC -c -o rtmp.o rtmp.c 
铛：错误：无效的版本号'-miphoneos-version-min = .sd'
 make：*** [rtmp.o]错误1 
  

为什么？我设置了 XLDFLAGS = - isysroot $ SDK -L $ LIBSSL / lib -arch $ ARCH -miphoneos-version-min = 7.0为什么无效的版本号在'-miphoneos-version-min = .sd'发生？

解决方案

I通过改变 -isysroot 参数来解决它： /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk

到：

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.3.sdk

请注意，后者是我系统中前者的符号链接。

它看起来，clang隐式地从iPhoneOSXXX.sdk目录名称中设置 -miphoneos-version-min = 。使用链接中的版本号似乎解决了编译问题。

When i compile librtmp for ios, the script shows below:

#!/bin/sh

# OS X Yosemite, Xcode 6.1

set -ex

DEVELOPER="/Applications/Xcode.app/Contents/Developer"
DEVICE_SDK="$DEVELOPER/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk"
SIMULATOR_SDK="$DEVELOPER/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk"
CURRPATH=`pwd`
SOURCE="rtmpdump"
DSTDIR="librtmp"
LIBSSL=`cd ../OpenSSL/libssl;pwd`
ARCHS="i386 x86_64 armv7 armv7s arm64"

rm -rf $DSTDIR
mkdir $DSTDIR

if [ ! -d $SOURCE ]; then
    git clone git://git.ffmpeg.org/rtmpdump $SOURCE
else
    cd $SOURCE
    git fetch
    cd ..
fi

cd $SOURCE/librtmp

for ARCH in $ARCHS; do
    mkdir -p ../$DSTDIR/$ARCH

    if [[ $ARCH == arm* ]]; then
        SDK=$DEVICE_SDK
    else
        SDK=$SIMULATOR_SDK
    fi

    perl -i -pe 's|^AR=\$\(CROSS_COMPILE\)ar|AR=xcrun ar|' Makefile

    CROSS_COMPILE="$DEVELOPER/usr/bin/" \
    XCFLAGS="-O0 -isysroot $SDK -I$LIBSSL/include -arch $ARCH " \
    XLDFLAGS="-isysroot $SDK -L$LIBSSL/lib -arch $ARCH -miphoneos-version-min=7.0 " \
    make SYS=darwin
    make SYS=darwin prefix="$CURRPATH/$DSTDIR/$ARCH" install
    make clean
done


mkdir -p $CURRPATH/$DSTDIR/lib
cd $CURRPATH/$DSTDIR/$ARCH/lib
LIBS=`ls *.a`
cd $CURRPATH
for LIB in $LIBS; do
    lipo -create `find $DSTDIR -name $LIB` -output $DSTDIR/lib/$LIB
done

cp -rf $DSTDIR/$ARCH/include $DSTDIR

for ARCH in $ARCHS; do
    rm -rf $DSTDIR/$ARCH
done

when statement make SYS=darwin runs, error shows:

/Applications/Xcode.app/Contents/Developer/usr/bin/gcc -Wall -O0 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk -I/Users/Smeegol/Desktop/AVCodecs2/OpenSSL/libssl/include -arch armv7   -DRTMPDUMP_VERSION=\"v2.4\" -DUSE_OPENSSL  -O2 -fPIC   -c -o rtmp.o rtmp.c
clang: error: invalid version number in '-miphoneos-version-min=.sd'
make: *** [rtmp.o] Error 1

Why? I have set XLDFLAGS="-isysroot $SDK -L$LIBSSL/lib -arch $ARCH -miphoneos-version-min=7.0 " and why invalid version number in '-miphoneos-version-min=.sd' occurs?

解决方案

I had the same problem and resolved it by changing the -isysroot argument from:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk

to:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.3.sdk

Note that the latter is a symlink to the former on my system.

It appears that clang is implicitly setting -miphoneos-version-min= from the iPhoneOSXXX.sdk directory name. Using the link with the version number in it seems to fix the compilation issue.
