无法为iOS编译LAME [英] Can't compile LAME for iOS

问题描述

我正在尝试将蹩脚的 mp3 编码器编译为适用于 iOS 的静态库.我想支持所有架构，包括i686，armv6，armv7，armv7s和arm64.这是我的构建脚本:

I'm trying to compile lame mp3 encoder as static library for iOS. I'd like to support all architectures including i686, armv6, armv7, armv7s and arm64. Here is my build script:

#!/bin/bash
DEVELOPER=`xcode-select -print-path`
SDK_VERSION="7.1"
mkdir build
function build_lame()
{
    make distclean
    ./configure \
    CFLAGS="-isysroot ${DEVELOPER}/Platforms/${SDK}.platform/Developer/SDKs/${SDK}${SDK_VERSION}.sdk" \
    CC="${DEVELOPER}/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -arch ${PLATFORM} -miphoneos-version-min=7.0 " \
    --prefix=/Users/mcrute/Desktop/lame \
    --host="arm-apple-darwin9" \
    --disable-shared \
    --enable-static \
    --disable-decoder \
    --disable-frontend

make -j4
cp "libmp3lame/.libs/libmp3lame.a" "build/libmp3lame-${PLATFORM}.a"
}
SDK="iPhoneSimulator"
PLATFORM="i686"
build_lame
SDK="iPhoneOS"
PLATFORM="armv6"
build_lame
PLATFORM="armv7"
build_lame
PLATFORM="armv7s"
build_lame
PLATFORM="arm64"
build_lame
lipo -create build/* -output build/libmp3lame.a

所以错误看起来像这样:

So the error looks like this:

configure: error: in `/Users/ivan/Desktop/lame-3.99.5':
configure: error: C preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details
make: *** No targets specified and no makefile found.  Stop.
cp: libmp3lame/.libs/libmp3lame.a: No such file or directory

此处是我的 config.log .|试图从构建目标中删除arm64，但脚本也失败，并出现相同的错误.Google说我还没有gcc，但是我有..寻找任何建议！

Here is my config.log. | tried to remove arm64 from build targets, but script also failed with same error. Google said that I haven't got gcc but I have.. Looking for any suggestion!

推荐答案

问题通过在configure函数中添加CPP =" * "变量解决.我的环境中错过了CPP.编辑后的构建脚本应如下所示:

The problem was solved by adding CPP="*" variable inside configure function. CPP was missed in my env. Edited build script should looks like this:

#!/bin/bash

DEVELOPER=`xcode-select -print-path`

SDK_VERSION="7.1"

mkdir build

function build_lame()
{
    make distclean

    ./configure \
    CPP="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cpp" \
    CFLAGS="-isysroot ${DEVELOPER}/Platforms/${SDK}.platform/Developer/SDKs/${SDK}${SDK_VERSION}.sdk" \
    CC="${DEVELOPER}/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -arch ${PLATFORM} -miphoneos-version-min=7.0 " \
    --prefix=/Users/ivan/Desktop/lame-3.99.5 \
    --host="arm-apple-darwin9" \
    --disable-shared \
    --enable-static \
    --disable-decoder \
    --disable-frontend

    make -j4
    cp "libmp3lame/.libs/libmp3lame.a" "build/libmp3lame-${PLATFORM}.a"
}

PLATFORM="i686"
SDK="iPhoneSimulator"
build_lame

PLATFORM="armv6"
SDK="iPhoneOS"
build_lame

PLATFORM="armv7"
build_lame

PLATFORM="armv7s"
build_lame

PLATFORM="arm64"
build_lame

lipo -create build/* -output build/libmp3lame.a
