Bug 68934

Description Tanya Wolff 2004-06-29 17:30:45 EDT

I am trying to debug a cygwin executable which has a function in a dll project.
I can debug the exec, but can't get into the dll code.
Parsers for both projects are CygwinPEparser.
I've also added to the debug configuration/source tab the source 
location .../ProjB. When I tried to add the directory containing the shared 
library to the Cygin GDB Debugger options/Shared Libraries tab, it gets 
forgotten, or erased when I apply and switch tabs and come back.
When I start debugging, the error dialog entitled "Errors Running Operations" 
appears with message:
Launching (Error: Faile Launching CDI Debugger)and I can't continue.

Here's the setup from Sean. 
If you want to test a simple DLL, create two projects, ProjA (executable) and 
ProjB (DLL). In ProjB add a *file* (classes can be done but you have to export 
an interface and that is probably a bit advanced for the basic test case) 
called hello.cpp and put the following code in it:

#include <iostream>

void hello() {
	using namespace std;
	cout << "Hello World!\n";
}  

Set the project's linker settigns to build a shared library (check shared and 
ignore the other settigns for now).

In ProjA, create a main.cpp file with the following contents:

extern void hello();
int main () {
	hello ();
	return (0);
}

In A's settings, set the linker library search path to ../../ProjB/Debug and 
its libraries to ProjB. 

Make ProjA reference ProjB and build. Copy the cygProjB.dll file into the 
build directory of ProjA and debug.
