如何用modelsim调试PLI程序 [复制链接]

大家好，我现在问题是不会用modelsim调试PLI程序，看网上资料和用户手册也没弄明白，还总是报错：
# ** Error: Setting bp 'Unable to set breakpoint, location not executable simMaster.c:104'求高手给出详细步骤，谢谢！

我的开发环境是：
Windows xp sp3
modelsim se6.5b
gcc-4.2.1-mingw32

这个问题困扰我好久了，问题解后马上结贴。

从你在http://communities.mentor.com/mgcx/message/7571上给出的信息来看，可能是因为你生成的dll是不能debug的，所以不能在dll运行的上下文中设断点。
是否可以将dll编译成可以debug的版本，或者不在dll中设断点。
在linux下，静态库编译成可调适版本是可以断点的，但是动态库并不清楚。

I searched the  ModelSim SE User's Manual  to find out how to debug. I  want to use cDebug to debug my PLI application, I followed the manual
to Specifying Path in C Debug setup Dialog:C:/modeltech_6.5b/win32/gdb.exe. and then I set a breakpoint in my PLI source file. when I try to run the PLI application. modelsim  display an error message:# ** Error: Setting bp 'Unable to set breakpoint, location not executable simMaster.c:104'. now I do not know what to do.

There are bugs in my application, so I want to know what to do to make  debug possable.Should I set something else to make modelsim debugable  like vc6.0. could you tell me how to config modelsim to debug in more  detail,because this problem bother me for a long time.


I followed these steps


>1. Start C Debug by selecting Tools > C Debug > Start C Debug


>2. Select Tools > C Debug > Init mode.
>3. Load my design.
>4 Set the breakpoint on the starting function of your PLI code by using
>the command bp -c
>5 step to debug your code.

modelsim displayed thoes messages after what I did:
