Hello
A new user to ECLIPSE on MAC OSX is here.
I cannot figure out what is wrong in using gdb with Eclipse.
The gdb debugger does not appear to be stopping at any breakpoint. It appears as if the execution has stalled.
All debug buttons ("Step Over", "Step Into") are deactivated/disabled.
-----------
I am showing the issue through a "Hello World" example: Created by
File->New->Project-> C/C++ project-> A CMake Project with a Hello World Executable to get started->test-hello-world-> finish
The project builds perfectly.
Debug Configuration is shown in the attached screenshot.
After that, using
Run->Debug History->test-debug-hello-world
leads to nothing.
My console shows the message
Building in: /Users/egad/eclipse-workspace/test-hello-world/build/cmake.debug.macosx.x86_64
cmake --build . --target all
[100%] Built target test-hello-world
Build complete (0 errors, 0 warnings): /Users/egad/eclipse-workspace/test-hello-world/build/cmake.debug.macosx.x86_64
------------------------------------------------------------------
An update
I found what could be the reason. It has to do with gdb 10.1.
The word is that this error could be a result of bug (link is here).
This bug causes gdb 10.1 to crash. The message of the gdb crash is identical to the message produced by eclipse on the Debugger Console, which I include at the bottom.
I have tried the same bug reproducing scenario (here) on gdb 8.1 on my LINUX VM.
There was no crash with gdb 8.1.
Alas, I cannot go back to gdb 8.1 on my MAC OSX, since I upgraded with the Mac Ports, which would not let me to downgrade, or apparently not easily without breaking something else.
It looks that I will have to wait until GNU wakes a new version of gdb to fix this bus.
