Dear Eclipse C++ Experts,

I can no longer set breakpoint in Eclipse Version: Neon.3 Release (4.6.3),
Build id: 20170314-1500, MinGW_64 (Posix) on Windows 10 (64bits) in the last
2 days on any C++ programs including a simple Hello World below:

#include <iostream>
using namespace std;

int main() {
	cout << "!!!Hello World!!!" << endl; // tried to set breakpoint on this line
	return 0;
}

This program & others runs fine in Eclipse.

The debug error are as follows:

Warning:
Cannot insert breakpoint 1.
Cannot access memory at address 0x75af355b

Not sure whether it is related to the following informative message after successful project built:
"Info: Configuration "Debug" uses tool-chain "MinGW GCC" that is unsupported on this system, attempting to build anyway."

Re-installing MinGW_64 (Posix) failed to make a difference. I
wouldn't mind re-installing Eclipse but not sure whether it will make any
difference & how to do it.

The following Windows environment variables have been set:
MinGW_HOME=C:\MingW\mingw32;
PATH=C:\MingW\mingw32\bin;

These variables are set in Eclipse Preferences,C/C++,Build,Environment variable

I need to use the debugger to troubleshoot more complex programs.

I couldn't find recent post on this issue & would appreciate any advice after
having spent days on trying to fix it without success.

This feature was working after initial installation earlier last week.

Thanks in advance,

George

Is this an active forum? Are there any moderator monitoring any post? Is there anything I have missed or am I posting to the wrong forum altogether?

I like to continue using Eclipse IDE but may need to look at other product if no community support is available.

Any assistance or guidance would be much appreciated.
Thanks,

George

This looks a little like there is a breakpoint in the Breakpoints window that is set incorrectly. Do you have a pop-up as well when it fails? Try removing all breakpoints.

Yes, but the way I monitor new posts broke last week and I didn't realize that there were posts until I saw your new post this morning.

I managed to removed MinGW64 and remove Eclipse Neon C++ IDE in the extracted folder C:\Software Development\Download\eclipse-cpp-neon-3-win32-x86_64\eclipse followed by reboot Windows 10.

I then extracted Eclipse to C:\Software Development\eclipse-cpp-neon-3-win32-x86_64\eclipse and install MinGW using the correct installer from www.mingw.org successfully.

Have also updated MINGW_HOME=C:\MinGW and PATH=C:\MinGW\bin on Windows environment variables and in Eclipse Preference C/C++ Build Environment.

Both Eclipse & MinGW are working except the step into / over (F5/F6) debugger function are not available / active, even though it does stop at the breakpoint that was set. The only option available in is to terminate the Hello World program.

Have I missed anything else.

Any assistance would be appreciated before I give up using this product and just buy VS2017 that does not have any of these hassles.

Thanks,

George

Are you finding the Resume (F8) is enabled, but step is not? Do you have a Frame selected in the Debug view (as opposed to a launch)?

index.php/fa/29559/0/

If that is not the problem, then this is a new one for me. Please help me to reproduce it.
