"cmake -DCMAKE_BUILD_TYPE=Debug" should be enough to get gdb debuggable
binaries.
Is the process which you intend to debug running when you ask gdb for a
backtrace?
You will only be able to get a backtrace if the process has been started
and has not yet exited.
e.g.:
gdb ./mybin
break main
run
backtrace

Hi,
I'm trying to debug my program using GDB. I've done the following:
-DCMAKE_BUILD_TYPE=Debug
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -g")
SET(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -g")
But whenever I run GDB and do a backtrace, I get a message: "No Stack".
I've done a Google search and apparently the -g flag is never passed
to g++.
Is -g automatically added when my build type is "Debug"? Does anyone
know why GDB gives me this error?
Thanks
Chris
