libjing 编译 for iphone simulator (..完善中..)

============================================================博文原创，转载请声明出处电子咖啡(原id蓝岩)============================================================上面说道在mac下面编译成功，我们开始在iphone下面编译********
修改main.scons的sdk (两处)
'-isysroot', '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk',***************
在libjingle.scons中注释一下代码，因为ios不支持mac中的部分framework
# "base/macutils.cc",
# "base/proxydetect.cc",

1.
首先修改/ilibjingle/gtalk/libjingle-0.5/talk下面的 main.scons，修改
'-isysroot', '/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.0.sdk',
为
'-isysroot', '/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk',或是对应其它版本的sdk，我刚开始没有修改，因此遇到了下面的问题：
MacmatoMacBook:talk Mac$ /swtoolkit/hammer.sh

在”FRAMEWORKS字段中，加入下面几个framework，（小心重复！）
'CoreAudio', 'QuickTime', 'Cocoa', 'QTKit'

2.
将third_party中对应的“expat-2.0.1”，“openssl-1.0.0”，“srtp“拷贝过来，注意重命名。

现在 /swtoolkit/hammer.sh 编译会出现错误：

不清楚原因，先往下面配置再说。 http://www.chinaunix.net/old_jh/15/578775.html
根据这篇博客执行命令，貌似有理，但依然失败
ln -s /usr/local/ssl/include/openssl /usr/include/openssl fix:
先将openssl编译，
$ ./config
$ make
$ make test
$ make install
然后在talk.Library(env, name = "libjingle", 中加入对应的include
includedirs = [
"third_party/expat-2.0.1/",
"third_party/srtp/include",
"third_party/srtp/crypto/include",
"third_party/openssl-1.0.0/include",
],

这个问题是刚才的openss是通过arm指令集编译的（我也忘了是什么时候编译的了），我们需要通过源码再i386下进行重新编译才行，--或许一直到ios真机的时候，还需要用arm重新编译

在 libjingle.scons 中，注释以下代码，因为IOS不支持这些（mac os x 上是支持的）# "base/macutils.cc",
# "session/phone/devicemanager_mac.mm",
# "base/proxydetect.cc",
(2)Add some Header serach directory in includedirs.like: includedirs = [
"third_party/expat-2.0.1/",
"third_party/srtp/include",
"third_party/srtp/crypto/include",
"third_party/openssl-1.0.0/include",
],编译，出现以下错误：________Compiling build/dbg/obj/session/phone/channel.o

原因：gcc里如果加上 -Werror 来严格检查编译环境使用它能够使gcc产生告警也认为是错误，方案：修改main.scons中，注释” # '-Werror',“ # '-Werror',
继续编译，出现新问题：_______Compiling build/dbg/obj/base/unixfilesystem.o

FSFindFolder是在CoreService.framework中声明的，iphoneSimulator中是有的，或许是其它问题
kOnAppropriateDisk在simulator中没有生命，而在mac os x 的sdk中生命了，因此把他注释掉。因此我判断是两者sdk不兼容的问题，
EventRef 再整个文件系统中找不到对应定义的地方，但读文档和源码（NSEvent），知道他是只支持 10.5以上的sdk，因此ios不兼容

解决方案，（但可能会留下问题）：注释 libjingle.scons中的下面句子，是上面报错的语句不再执行
# "base/unixfilesystem.cc",
此问题解决，但出现了新问题：

 “UnixFilesystem” 虽然我已经注释掉了，但是 libjingle.a是我在mac下的libjingle编译后直接copy过来的，因此mac下会用到“UnixFilesystem”因此产生冲突，我需要自己在ilibjingle下重新编译出libjingle.a才行。

发现 “/ilibjingle/gtalk/libjingle-0.5/talk/build/dbg/lib”下面的文件，出了libcryto和libssl是openssl编译创建然后copy过来的，剩下的都是在“/swtoolkit/hammer.sh ”时候创建的

还是没有头绪，随便测试，这时候进入openssl，进行make编译，出现以下错误，不知道是否和现在的环境有关，同时在mac上的成功 libjingle 编译，也会出现同样的错误，不知道什么原因

删除gdb下面的所有库，重新copy新的openssl，再进行编译试试
还是不行，编译错误，先不管。

上面的方案不对，
再报错文件 unixfilesystem.cc 中，找到对应的代码，看到是定义了OSX才调用 FSFindFolder，
#ifdef OSX
FSRef fr;
if (0 != FSFindFolder(kOnAppropriateDisk, kTemporaryFolderType,
kCreateFolder, &fr))
return false;
unsigned char buffer[NAME_MAX+1];原因找到了，我们再main.scons中注视到对应变量
mac_env.Append(
CPPDEFINES = [
# 'OSX',
'MAC_OS_X_VERSION_MIN_REQUIRED=1040',

scons: *** [build/dbg/obj/base/physicalsocketserver.o] Error 1

和上面是同样的问题，同样方法，找到错误文件，发现：
#elif defined(OSX) || defined(BSD)
LOG(LS_WARNING) << "Socket::OPT_DONTFRAGMENT not supported.";
return -1;
#elif defined(POSIX)
*slevel = IPPROTO_IP;
