gdb <value optimized out>

[G VM]

I got a step further.
It seems that both -g3 -O0 and -g -O2 are in the c++ compilation lines (make -n).
So the second take priority over the first.

However I still can't understand were those -g and -O2 are configured.
The CMAKE_CXX_FLAGS_DEBUG and CMAKE_CXX_FLAGS don't have these.

If I do a grep for -O2 and remove those, and then do make all works as it should.

touch rdp/rdpview.cpp
cd build
make -p | grep rdpview

Hopefuly this helps finding the cause.

Subject: gdb <value optimized out>
Date: Sat, 11 Dec 2010 16:59:27 +0100








Hi all,

I have been searching for a solution for my problem but unfortunately I didn't find a solution.

Problem:
When I start my compiled program with gdb and want to print the value of an integer (probably other data types as well) I get the message <value optimized out>.
I am a gentoo user so I am aware that -O exists.
So I went searching in KDevelop on how to configure this.

I changed some flags in the "Open Options", "Advanced settings" to use -O0.

CMAKE_CXX_FLAGS

CMAKE_CXX_FLAGS_DEBUG

CMAKE_C_FLAGS

CMAKE_C_FLAGS_DEBUG
...

And on the kdevelop forum I found a thread which mentioned using -g3 as well.
I did this, cleaned and recompiled the program. But still I have the same result.

I really have no clue anymore what I am doing wrong.
Anyone has an idea about this?

I use:


Version 4.0.2 (using KDevPlatform 1.0.2)
Using KDE Development Platform 4.4.5 (KDE 4.4.5)
Program I want to compile to debug is Krdc.

Thanks in advance for your help!
