How many resources like shared_memory ROSCPP used?

Question

I want to ask this question because of I found that if I don't care about resources,sometimes it will run into strange producure.

For example, when some code A run successfully.

I change to A' and failed.

So I change back to A but also failed.

Therefore, I think it maybe caused by system resources.

So my question is:

When I rebuild ROSCPP and want to run it, which resource I should remove first by tools similar to ipcs?

Thank you~

When you change things you only need to recompile. Make sure that you have recompiled all your libraries and their dependencies which connect to the changes you made. In general a rosmake will cover everything. There are a few packages, usually 3rd party packages that download external sources, where a make clean is necessary.

So what you mean is roscpp doesn't use any system resources like shared memory? Thank you~
