Hi,
I hope someone can assist here. I couldn't come with better title, sorry.
I write a test application and I want to run the compiled code without
installing. So I build using make -f debian/rules build and then run
LD_LIBRARY_PATH=obj-x86_64-linux-gnu/src/testapp
obj-x86_64-linux-gnu/src/testapp/testapp
but I do not get any debugging symbols and no debugging output with kdDebug.
tqDebug works, but this is not what I want.
How can I compile so that I can have the debugging with kdDebug without
building dbgsym packages.
Does someone have an advise.
thanks

Hi Emanoil,
first of all, kdDebug and debug symbols are two independent concepts.
dbgsym are symbols that can be used when debugging the program within a debugger like
gdb.
kdDebug is a stream object that let you print messages to a stream, regardless of whether
you have installed debug
symbols or not.
If tdelibs is built in release or RelWithDebInfo (in debian), kdDebug won't print any
info. If tdelibs is built in debug
mode, kdDebug will work as expected.
Cheers

RelWithDebInfo
Thank you tdelibs is OK
tdelibs$ grep Debug -r debian/rules
-DCMAKE_BUILD_TYPE=Debug
it seems that I had to set this flag in the application as well - obviously!
thank you for the hint

in this context, what is DrKonqi using to display the debug?
I do not see there the backtrace, when it crashes so what should I do to see
it (when I run the application from the place it was build)
thanks

DrKonqui uses a backtrace, pretty much capturing the same info you would see in gdb when
looking at the backtrace after
a crash. If you have debug symbols installed, those will be used to display additional
info about the crash (either by
DrKonqui or gdb).
There is a kdBacktrace() function in kdebug.cpp in tdelibs which builds a backtrace. You
can print a backtrace
programmatically even without a crash by using it in your code.
