Hi all, I was trying to use two gmapping packages, one is the original one, and the another is modified one. Following is what I did:

  1. clone gmapping package

  2. rename the folder (slam_gampping_modi)

  3. modify CMAKE file

  4. compile

But it just destroyed everything, somehow my AMCL didn't work. (which is another one mystery and I had to reinstall my ubuntu this afternoon

I think the problem is the modification of CMAKE file, so could anyone please tell me which part of this file I need to change so it will be dealt as a new package?

yeah I admit it, it seems like a xy-problem now...what I'm trying to do is solve my previous questionlink text. I thought I can realize my goal by change a default parameter in the source code, but I still need the ..

original one, so that's where this question came from. I guess the right thing to do is write a subscriber, but I don't know how to load this subscribed map into a local variable of a function. Because I was a new bee lol, that's also the reason I reinstall my system, to me that's the fastest way
