ios的make file例子

具体的例子暂时没有，下面的文章供参考：

1. x264的编译

首先到http://www.videolan.org/developers/x264.html下载x264的库，然后解压。

打开shell，进入x264的目录，执行如下语句

CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc ./configure --host=arm-apple-darwin --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk --prefix='dist' --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7 -L/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/usr/lib/system' --enable-pic

然后make，libx264.a就出来啦。如果无法执行，请将语句中的5.0.sdk替换成你电脑里面有的sdk。

2. 如何通过Makefile编译iphone的openSSL

这两天接受了一个新任务，就是学在iphone和android平台上编译openSSL，因为我对Apple知之甚少， 所以在做的过程中遇到了 一些困难和问题，经过学习和尝试，终于弄出来了，网上的好多教程有问题，所以自己根据自己的经验，写一篇博文和大家分享一下。

版本：OpenSSL 1.0.0e 

Xcode 4 with iOS 4.

注意：根目录定为我的本家目录即/Users/jianke.tang/

下面开始我们的旅程
1. 下载openSSL(http://www.openssl.org/source/)，修改源代码

下载下来的以后进行解压，为了避免编译错误，需要进行稍微的修改，打开 crypto/ui/ui_openssl.c，然后将

static volatile sig_atomic_t intr_signal;

改为

static volatile int intr_signal;

2. 创建一个放置不同平台的库

$ mkdir ssllibs

3. 为i386模拟器编译openssl

$ cd openssl-1.0.0e

$ mkdir openssl_armv6 openssl_armv7 openssl_i386

$ ./Configure BSD-generic32 --openssldir=/Users/jianke.tang/openssl-1.0.0e/openssl_i386

修改Makefile文件

$ vi Makefile

a.找到

CC = cc

将其改为

CC= /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc -arch i386

b.就在这行下边找到CFLAG, 在'='后面添加

-isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk

c.编译安装

$ make

$ make install

d.复制到上面建立的库中

$ cp -r openssl_i386 ../ssllibs

注:i386只有基于模拟器的，没有OS的，所以基于arm的和i386的是不一样的

4.为armv6 ios编译openSSL

$ make clean

$ ./Configure BSD-generic32 --openssldir=/Users/jianke.tang/openssl-1.0.0e/openssl_armv6

修改Makefile文件

a.找到

CC = cc

将其改为

CC= /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -arch armv6

b.就在这行下边找到CFLAG， 在'='后面添加

-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk

c.编译安装

$ make

$ make install

d.复制到上面建立的库中

$ cp -r openssl_armv6 ../ssllibs

注：请注意，一定确保相关路径下有该文件，否则会出现编译错误，比如iPhoneOS4.3.sdk可能是iPhoneOS4.0.sdk版本的

5. 为armv6 ios编译openSSL5. 

$ make clean

$ ./Configure BSD-generic32 --openssldir=/Users/jianke.tang/openssl-1.0.0e/openssl_armv7

修改Makefile文件

a.找到

CC = cc

将其改为

CC= /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -arch armv7

b.就在这行下边找到CFLAG,在'='后面添加

-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk

c.编译安装

$ make

$ make install

d.复制到上面建立的库中

$ cp -r openssl_armv7 ../ssllibs

6. 库的处理

打开库ssllibs，在各个平台下的lib/中的libcrypto.a和libssl.a，以及在各个平台下的include文件夹

好了，我们可以创建一般性的链接库了，这样可以保证它可以根据平台自动选择。

$ lipo -create ../ssllibs/openssl_i386/lib/libcrypto.a ../ssllibs/openssl_armv6/lib/libcrypto.a openssl_armv7/lib/libcrypto.a -output ../ssllibs/libcrypto.a

$ lipo -create ../ssllibs/openssl_i386/lib/libssl.a ../ssllibs/openssl_armv6/lib/libssl.a openssl_armv7/lib/libssl.a -output ../ssllibs/libssl.a

7.到这里就大功告成了，不过为了帮助大家更更好的理解和使用，这里我教大家如何修改IPHONE-XCODE PROJECT

1. Copy the “include” folder from OpenSSL into your project-folder

2. Copy the libcrypto.a and libssl.a files into your project-folder

3. Drag the libcrypto.a and libssl.a files into your XCode Framework Folder-Tree

4. Open the Build-Info from your “Target” (Righclick on Target – Get Info)

    Change Library Search Paths to 

       $(inherited) "$(SRCROOT)"

6. Change User Header Search Paths to include

7. Activate Always Search User Paths

8. 这里有个例子工程，大家可以参考一下，别的我就不赘述了 http://github.com/x2on/OpenSSL-for-iPhone。

这个库是iOS 3.2/4.0 XCode Project with OpenSSL 1.0.0a

使用了MD5-algorithm to calculate an md5 hash from an UITextfield.

3.以samba讲解如何交叉编译开源库用于iphone平台

首先设定iphone编译环境

红色为我自定义的编译samba时候设置一些环境，可以改

1>

export LDFLAGS="-L/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/lib -L/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/lib/system"

2>

export PATH=$PATH:/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/

3>(举例编译samba库)

./configure --prefix=/Users/kanoutouyetao/samba-iphone  CC=arm-apple-darwin10-gcc-4.2.1--enable-static --without-readline --with-libsmbclient CPPFLAGS="-I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/lib/gcc/arm-apple-darwin10/4.2.1/include -I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/include" --host=arm-apple-darwin10 --build=x86

在./configure中出现 cannot run test program while cross compiling

错误修改之：
cannot run test program while cross compiling
修改以下文件：

＋，表示添加

－，表示减去
1】
--- samba-3.3.3/source/configure       
+ ../c-programm/samba-3.3.3/source/configure 
 
 { $as_echo "$as_me:$LINENO: checking that the C compiler understands negative enum values" >&5
 $as_echo_n "checking that the C compiler understands negative enum values... " >&6; }
+samba_cv_CC_NEGATIVE_ENUM_VALUES=stz（加入）
 if test "${samba_cv_CC_NEGATIVE_ENUM_VALUES+set}" = set; then
   $as_echo_n "(cached) " >&6
 Else
2】先运行configure后，在修改

+#define HAVE_LBER_LOG_PRINT_FN 0

-#define HAVE_LDAP_H 1
+#define HAVE_LDAP_H 0

./configure

make

(说明，因为我编译为静态库，所以需要全部静态库)

make install

或者参考

http://hi.baidu.com/foxms/blog/item/b694ef2607cccd38c89559c4.html

 在编译时候添加samba_cv_CC_NEGATIVE_ENUM_VALUES=yes

3>

./configure --prefix=/Users/kanoutouyetao/samba-iphone  CC=arm-apple-darwin10-gcc-4.2.1 --enable-static --without-readline --with-libsmbclient --disable-cups -disable-iprintsamba_cv_CC_NEGATIVE_ENUM_VALUES=yes CPPFLAGS="-I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/lib/gcc/arm-apple-darwin10/4.2.1/include -I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/include" --host=arm-apple-darwin10 --build=x86

我编译的是samba-3.3.3的，不为何samba3.6.4的编译真机的时候没有成功！

编译仿真器上的库

成功编译出i386的库，并且可以调用

当然，使用此库的时候需要添加

-lresolv -liconv两个库！在xcode lib里面添加 ，如图
