           Summary: C++ CMake hello world project cannot be debugged
           Product: kdevelop
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Appwizard Templates
        AssignedTo: kdevelop-bugs kdevelop org
        ReportedBy: yezonghui gmail com


Version:            (using KDE KDE 3.5.5)
Installed from:    Debian testing/unstable Packages
OS:                Linux

Create a C++ CMake "hello world" project using the "New Project" Wizard. Then try to \
debug it. This happens:

1. When I hit F9 (or select menu item "Debug->Start"), the program simply runs to \
end, no matter how many and where I put break points (they are always grey, \
indicating not successfully added to the debugged program).

2. When trying to debug the compiled hello world program directly using gdb (ie. \
outside of kdevelop), setting a break point at main("break main"), run it("run"), the \
break point is hit but try "next" or "step" after this, gdb shows "Single stepping \
until exit from function main,which has no line number information." and stops in \
__libc_start_main ().

Finally I found out that I must manually modify CMakeLists.txt in the project folder, \
changing  ADD_DEFINITIONS(-Wall -O2)
into 
ADD_DEFINITIONS(-Wall -g -O0)
to enable normal debug.

I think there should be some "Enable debug" option in the "project options" Dialog, \
or a "debug " target made avaiable in the "build targets" menu, or anything that do \
not require manual modification of CMakeLists.txt just to bring up debugging.
