Code::Blocks and Eclipse same debugger error "No symbol table loaded"

[blisca]

Hello

i need some help,please

I have installed two c++ environment
Code::Blocks and Eclipse Oxygen

In both cases a simple "Hello world" project is compiled with 0 errors 0
warnings,
but i can't debug it.
If i set a breakpoint i have this error:

No symbol table is loaded. Use the "file" command.

I read lot of forum for similar question,checked all the boxes (i
think)having to do with debug information generation,but no way

Should i re-install MinGw oe what?

Please can you help me?

Thank you so much for your attention

I'm going to guess you're running Linux and Gnu tools.

There's a switch "-g" to the Gnu compilers to make them generate debug
information.

And turn that thing off please. There is an option somewhere in the tool.

And I'm guessing the IDE has an option to do "debug" builds,
which enables the option under the hood.

IMO, one should always build with -g. It doesn't cost anything but
disk space, and it lets you debug core dumps, debug with valgrind and
so on. And you can always strip the binaries later, if it becomes
necessary.
