osip及eXosip的編譯及開發方法

osip及eXosip的編譯方法

在最新版本的osip2、exosip2中不支持在VC6.0下編譯osip、exosip協議棧的方法

說明：
1.以下文章中的osip版本爲3.1.0
2.eXosip版本爲3.1.0
3.編譯環境爲：Windows XP 專業版本+VS 2005
4.實例程序下載：http://download.csdn.net/source/617797
5.osip、exosip、openssl的開發包下載，開發包包括：osip2.dll、osipparser2.dll、exosip2.dll、libeay32.dll、ssleay32.dll和相對應的lib文件，下載地址同上

第一步，下載：
到http://download.savannah.gnu.org/releases/osip/libosip2-3.1.0.tar.gz
下載最新的osip庫並解壓
到http://download.savannah.gnu.org/releases/exosip/libeXosip2-3.1.0.tar.gz
下載最新的eXsoip庫並解壓
第二步，編譯osip3.1.0：
1.用VS2005打開libosip2-3.1.0/platform/vsnet/osip.sln
2.對osip2和osipparser2項目生成Release DLL
3.其生成的LIB/DLL 位於：libosip2-3.1.0/platform/vsnet/Release DLL/下
4.如果有出現外部變量找不到的情況，很有可能是生成的dll沒有實現該函數，在def文件中刪除找不到的外部變量就好了
第三步，編譯eXosip3.1.0：
1.用VS2005打開libeXosip2-3.1/platform/vsnet/eXosip.sln
2.將libosip2-3.1/include/osip2目錄COPY到libeXosip2-3.1/include/下
3.將libosip2-3.1/include/osipparser2目錄COPY到libeXosip2-3.1/include/下
4.在libeXosip2-3.1目錄下新建lib目錄
5.將“第二步”中生成的libosip2-3.1/platform/vsnet/Release DLL/osip2.lib文件COPY到libeXosip2-3.1/lib目錄下
6.將“第二步”中生成的libosip2-3.1/platform/vsnet/Release DLL/osipparser2.lib文件COPY到libeXosip2-3.1/lib目錄下
7.修改項目屬性，新增Dnsapi.lib Iphlpapi.lib Ws2_32.lib osip2.lib osipparser2.lib庫輸入
8.修改項目屬性，新增庫目錄../../lib
9.修改項目的輸出爲.DLL，默認爲.lib
10.編譯Relase DLL
11.其生成的LIB/DLL 位於：libeXosip2-3.1/platform/vsnet/Release/下

注意：

在eXoSip.def 中添加下面函數的導出,不知道是爲什麼 這些函數沒有導出!
     eXosip_call_set_reference

    eXosip_call_build_initial_invite

    eXosip_call_send_initial_invite

    eXosip_call_build_request

    eXosip_call_build_ack

    eXosip_call_send_ack

    eXosip_call_build_refer

    eXosip_call_build_info

    eXosip_call_build_options

    eXosip_call_build_update

    eXosip_call_build_notify

    eXosip_call_send_request

    eXosip_call_build_answer

    eXosip_call_send_answer

    eXosip_call_terminate

    eXosip_call_build_prack

    eXosip_call_send_prack

    eXosip_call_get_referto

    eXosip_call_find_by_replaces

編譯osip可能會出現如下錯誤：

1：在osipparser.dll的def文件會出現幾個拼寫錯誤，如缺少MD5_****的函數前面缺少osip_,使得連接器出現link2019錯誤，解決方法是在前面加上osip_

2：但是如果在編譯的時候出現錯誤：

libnet_prand.obj : error LNK2001: unresolved external symbol __imp__CryptReleaseContext@8
libnet_prand.obj : error LNK2001: unresolved external symbol __imp__CryptGenRandom@12
libnet_prand.obj : error LNK2001: unresolved external symbol __imp__CryptAcquireContextA@20
Debug/Libnet.dll : fatal error LNK1120: 3 unresolved externals

仔細看了下，CryptReleaseContext等這三個函數不是從advapi32.lib裏導入的麼？難道要加上advapi32.lib庫？在項目設置的連接裏把advapi32.lib加上，然後rebuil all，果然成功。

如果出現是__RTC_CheckEsp這個外部變量無法解析，很大可能是兩個項目的配置不一樣，比如說一個能從父項目繼承什麼。另外一個沒有設置，就會出現這個問題。

編譯eXosip可能會出現的問題：

要包含頭文件：ssleay32.lib libeay32.lib Dnsapi.lib Iphlpapi.lib Ws2_32.lib osip2.lib osipparser2.lib kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib ，其中ssleay32.lib libeay32.lib是openssl的靜態庫。

可能還會找不到一些無法解析的外部變量，可能是在osip的輸出dll的def文件中沒有加上

     osip_transaction_set_srv_record     @122

然後重新編譯osip

外部變量問題，一般都是庫文件的問題，記住要把庫文件放在工程目錄lib目錄下（沒有lib目錄自己新建一個） 然後在工具->項目->c/c++->C++目錄下把設置../../lib設置成包含的目錄

其中ssleay32.lib libeay32.lib是openssl編譯形成的靜態鏈接庫，可以從網上下載，或者自己編譯

之外，尤其大家下載的源代碼由於認爲的或者是編譯環境的不同，容易造成多種錯誤，我還碰到了個無法解析的Osip_^^^!!#@!@#!函數無法解析的情況，在osip中的def文件一查，果然缺少個122的函數文件輸出聲明，加進去重新編譯osip，成功，在編譯eXosip成功！

最後運行實例,進行項目配置：
