Hello,

i am looking for a good way to debug my program. At the moment i only use screen output because eclipse debug mode is not working.

My problem is that i am using a ros node and this is calling my c++ library. Not i want to debug my library when ros is running.

How i can do this? When i am using eclipse he and i say debug my node he give me an error : No source available for "main() at 0x4277e8"

then i tested the gdb launch-prefix="gdb -ex --args"

but then i cant type anything inside the shell, because i have a few rosoutputs.

Can anyone please help me and explain me what is the best way for debuging this?

thank you for your help

I am not sure I understand your question, if you want to debug it with gdb, open a new terminal, type cd ~/<enter-your-package-path>/bin (or wherever the executable is) and then run the command: $ gdb node-name. gdb will launch and then you could type: run to run it or you could set breakpoints in your code by typing : break line-number , and whenever it stops at a break point you could type : continue to go to the next breakpoint. I am not sure if this answers your question but I hope it helps!

I still have a question about this. How do you call "rosrun" if you are using gdb. When I just try to run gdb on my executable, I get some boost errors and a SIGABRT flag.

Could you give a representative example? Thanks

i am not using rosrun. U can use roslaunch with the prefix or u can use eclipse. I am using eclipse at the moment and it works fine.

Qtcreator allows you to open a project by opening the cmake.list file, using this parameter makes the build a debug build therefore breakpoints can be set

hi, i still dont get it. i uese eclipse, but i cannot configure the "run configuration". the online tutorial says, i should see a list of executables when i click on "search project", but there is nothing. if i type in there rosrun ..., i can execute but not debug it says "Program is not a recognized executable.". however, i can build the whole package without problems, but indexer is not working for me as well. all in all, it is a huge mess
