opnet中如何建立自己的pipeline stage模型呢

我把pipeline stage的c文件中的wlan_ber.c另存为了My_wlan_ber.c，并且编译成My_wlan_ber模型。仿真时的ber model模型采用My_wlan_ber，在Rebuilding scenario model library这一步总是出错，而且环境变量我也都已经设置好了。：
<<< Recoverable Error >>>                                                  |
Object repository construction failed                                      |
due to errors encountered by the binder program (bind_so_msvc)             |
Errors reported by the binder program follow

谁能指点一下，先谢谢了

你编译了吗？修改完代码

编译过了，不编译的话应该无法出现新名称的模块吧

pipeline模型文件的入口函数名必须和文件名一致。比如wlan_ber.ps.c的入口函数必须叫wlan_ber()。
请注意这一条规定。
