无法建立我的程式 [英] cannot build my program

问题描述

我有一个cpp程序.该程序是一个软件电话(sip phone).我能够在没有错误或警告的情况下编译代码.

I have a cpp program. the program is a softphone(sip phone). i'm able to compile the code with no errors or warnings..

------ Build started: Project: test, Configuration: Debug Win32 ------

    Build: 1 succeeded, 0 failed, 0 skipped

该程序基本上使用来自sip堆栈(pjsip)的头文件.

但是当我尝试构建代码时，它会产生25个错误.

the program basically uses header files from a sip stack( pjsip)

but when i try to build the code it generates 25 errors.

谁能告诉我可能是什么问题..
我已经在我的项目属性中添加了以下内容..

在c ++中->一般情况下，我已经包含了pjsip头文件的路径.

我正在使用Visual Studio 2003(MS开发环境2003 v7.1.3088，MS .net framework 1.1 v1.1.4322)

任何帮助都将得到很好的应用.

在此先感谢

can any one tell me what could be the problem..
i have included the following in the my project properties..

in c++ -> general,  i have included the paths of the header files of the pjsip.

i'm using visual studio 2003 (  MS devlopment environment 2003 v7.1.3088, MS .net framework 1.1 v1.1.4322 )

any help would be very well appriciated.

thanks in advance

推荐答案

您需要在链接器设置中指定导入库.

You need to specify the import libs in the linker settings.
