如何将lame编译为iPhone的armv6和armv7的静态库(.a)？

发布于 2025-01-03 17:26:33 字数 2848 浏览 1 评论 0原文

LAME(http://lame.sourceforge.net/)是一个用c语言编写的库。它可以将 PCM 声音文件转换为 MP3 文件。我用它在 iPhone 上将声音文件转换为 MP3 文件。源PCM声音文件由麦克风录制。

为了将 LAME 包含到我的 XCode 项目中，我需要将 LAME 编译为 3 个静态库（.a），用于 i386（IOS 模拟器）、armv6 和 armv7。

经过大量搜索，我成功编译了 i368 版本（iOS Simulator）的静态库。这是命令：

./configure \
    CFLAGS="-isysroot  /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk" \
    CC="/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc -arch i386" \
    --prefix=/Volumes/Data/test/i386 \
    --host="arm-apple-darwin9"

make && make install

问题是我无法编译armv6 和armv7。我已经尝试过这个命令，但它报告错误。有没有人有解决办法？

./configure \
    CFLAGS="-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk" \
    CC="/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -arch armv6" \
    --prefix=/Volumes/Data/test/arm6 \
    --host="arm-apple-darwin9"

make && make install

错误是：

console.c:25:21: error: curses.h: No such file or directory
console.c:27:20: error: term.h: No such file or directory
console.c: In function ‘get_termcap_string’:

console.c:115: warning: implicit declaration of function ‘tgetent’
make[2]: *** [console.o] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

当我安装 ncurses 时，它报告了：

../curses.h:60:25: error: ncurses_dll.h: No such file or directory
In file included from console.c:25:
../curses.h:250: warning: return type defaults to ‘int’

../curses.h:554: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘addnstr’

是否有人可以给我一种将 LAME 编译为armv6和armv7的静态库（.a）的方法？

原文

LAME(http://lame.sourceforge.net/) is a library written in c language. It can convert PCM sound files to MP3 files. I use it to convert sound files to MP3 files on iPhone. The source PCM sound files is recorded by microphone.

In order to include the LAME into my XCode Project, I need to compile the LAME to 3 static libraries(.a), for i386(IOS Simulator), armv6 and armv7.

After a lot of search, I have complied a static library for i368 version(iOS Simulator) successfully. Here is commands:

./configure \
    CFLAGS="-isysroot  /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk" \
    CC="/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc -arch i386" \
    --prefix=/Volumes/Data/test/i386 \
    --host="arm-apple-darwin9"

make && make install

The problem is I can not compile for armv6 and armv7. I have tried this commands but it report an error. Is there anybody have solutions?

./configure \
    CFLAGS="-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk" \
    CC="/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -arch armv6" \
    --prefix=/Volumes/Data/test/arm6 \
    --host="arm-apple-darwin9"

make && make install

The error is:

console.c:25:21: error: curses.h: No such file or directory
console.c:27:20: error: term.h: No such file or directory
console.c: In function ‘get_termcap_string’:
console.c:92: warning: implicit declaration of function ‘tgetstr’
console.c:92: warning: assignment makes pointer from integer without a cast
console.c: In function ‘get_termcap_number’:

console.c:115: warning: implicit declaration of function ‘tgetent’
make[2]: *** [console.o] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

When I install ncurses, It reported this:

../curses.h:60:25: error: ncurses_dll.h: No such file or directory
In file included from console.c:25:
../curses.h:250: warning: return type defaults to ‘int’

../curses.h:554: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘addnstr’

Is there somebody can give me a way to compile LAME to static library(.a) for the armv6 and armv7?

你少了几个步骤。首先，您根本不想构建前端，因为无论如何您都只能使用 LAME 作为库。您还必须静态构建库，否则您将无法将其构建到项目中。

基本上，您必须设置源代码树并编译四次，一次用于模拟器 (i686)、iPhone (armv6)、iPad (armv7) 和 iPhone 5 (armv7s)，然后将 .a 文件一起放入通用库中。当您编译项目的其余部分时，Xcode 链接器将为您整理所有其他内容。

我使用这个 shell 脚本构建了一个通用的 libmp3lame.a 文件。请注意，这使用 Xcode 4.3 路径和 iOS 5.1 编译器。

#!/bin/bash

SDK_VERSION="5.1"

mkdir build

function build_lame()
{
    make distclean

    ./configure \
        CFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/${SDK}.platform/Developer/SDKs/${SDK}${SDK_VERSION}.sdk" \
        CC="/Applications/Xcode.app/Contents/Developer/Platforms/${SDK}.platform/Developer/usr/bin/gcc -arch ${PLATFORM}" \
        --prefix=/Users/mcrute/Desktop/lame \
        --host="arm-apple-darwin9" \
        --disable-shared \
        --enable-static \
        --disable-decoder \
        --disable-frontend

    make
    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

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

从 ./build 中获取 libmp3lame.a 文件以及 include 目录中的 lame.h 文件，并将它们放入您的 Xcode 项目中，您应该准备好在模拟器或真实设备中使用 lame。

You're missing a few steps. First of all you don't want to build the frontend at all since you'll only be able to use LAME as a library anyhow. You also have to build the library statically otherwise you won't be able to build it into your project.

Basically, you have to setup the source tree and compile it four times, once for the simulator (i686), iPhone (armv6), iPad (armv7) and iPhone 5 (armv7s) then lipo the .a files together into a universal library. The Xcode linker will sort everything else out for you when you compile the rest of your project.

I used this shell script to build a universal libmp3lame.a file. Note this uses Xcode 4.3 paths and iOS 5.1 compilers.

#!/bin/bash

SDK_VERSION="5.1"

mkdir build

function build_lame()
{
    make distclean

    ./configure \
        CFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/${SDK}.platform/Developer/SDKs/${SDK}${SDK_VERSION}.sdk" \
        CC="/Applications/Xcode.app/Contents/Developer/Platforms/${SDK}.platform/Developer/usr/bin/gcc -arch ${PLATFORM}" \
        --prefix=/Users/mcrute/Desktop/lame \
        --host="arm-apple-darwin9" \
        --disable-shared \
        --enable-static \
        --disable-decoder \
        --disable-frontend

    make
    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

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

Take the libmp3lame.a file from ./build along with the lame.h file from the include directory and drop them in your Xcode project and you should be ready to use lame in either the simulator or a real device.

对于 Xcode 6.1、iOS SDK 8.1，我使用以下 shell 脚本：

支持armv7、arm64、i686 和 x86_64

感谢@mcrute的出色回答，以及 XCode 5 要求更新 我已经更新了脚本。希望对新用户有用。

注意：不要忘记根据您的系统安装更新 SDK_VERSION

#!/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"
}

PLATFORM="i686"
SDK="iPhoneSimulator"
build_lame

PLATFORM="armv6"
SDK="iPhoneOS"
build_lame

PLATFORM="armv7"
build_lame

PLATFORM="armv7s"
build_lame

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

Thanks @mcrute for his great answer, and XCode 5 requirement update I have updated script. Hope it useful for new users.

NOTE: Don't forget to update SDK_VERSION based on your system installation

#!/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
