Eclipse Debugger Usage with gcc on WIndows [message #1863768] Mon, 26 February 2024 09:03 Go to next message

Hi,
currently I am working on a Windows project in C using Eclipse CDT, gcc C compiler and the Eclipse debugger. Starting programs in debug mode works. I have encountered 2 problems, maybe someone here can help me:

1. How do I programmatically invoke the Eclipse debugger? In ancient times I worked with Visual Studio and remember the Windows function DebugBreak(). I tried this, but it did not work. My project internally spawns several processes and I need to catch one of them in the debugger at a certain point. How can I achieve this?

2. The project uses several source modules from other projects. I use the Eclipse link feature (i.e. use the "Add file", "Advanced", "Link to file in file system") features in Eclipse. The project builds ok. I can debug and step into the "linked" source files. But setting breakpoints in these files is not working. The breakpoints are simply ignored. I am also using the Eclipse debugger for an exotic platform (HPE NonStop) using cross compilers. In this scenario breakpoints in "linked" files work, so it does not seem to be a "cannot be done" kind of limitation. Is there a setting to enable this?

Any help is appreciated, thank you very much.
Kind regards
Werner

Hello,
1. Invoking the Eclipse debugger programmatically can be achieved using the DebugBreak() function. However, DebugBreak() is a Windows-specific function and may not work with the Eclipse debugger. Instead, you can use the raise(SIGINT) function to generate a SIGINT signal, which can be caught by the debugger. Here's an example of how you can use it: geometry dash scratch
c
#include <signal.h>

int main() {
    // Your program code here

    raise(SIGINT); // Send SIGINT signal to invoke debugger

    // Rest of your program code
    return 0;
}

When you run your program and it reaches the raise(SIGINT) line, the debugger should be invoked and pause execution at that point.

2. I think the issue with breakpoints in linked source files might be related to the build configuration or the way the files are included in your project. I think you should make sure the linked source files are part of the build configuration. Go to your project properties, navigate to "C/C++ Build" -> "Settings" -> "Build Steps" -> "Build Artifact(s)", and ensure that the linked source files are included.
