I am trying to use RegionGrowingRGB and other functions which are available in pcl 1.7 but not 1.5. The issue I am having is that 1.7 does not contain the recent patch that was applied to 1.5 (which solved my segfault issue here).

My question is, is there any way I can mix versions in my code? I either want to use 1.5 but be able to call functions implemented in 1.7, or use 1.7 but be able to use the 1.5 version of files which were affected by the patch. Is there any easy way to do this?

I don't think I can simply copy the missing files into the 1.5 directory because I'm sure there are tons of dependencies.

If you are trying to use functionality that is only in PCL 1.7, then it is probably in your best interest to apply the patch from your other question to PCL 1.7 and just use that.

I'm going to guess that it will be significantly easier to fix the bug in 1.7 and build from source than it will be to backport all of the functionality to 1.5.

I was able to get it working by backporting the functions from 1.7 into 1.5. Hopefully there will be a patch to 1.7 before I need to backport any more functions. Thanks anyway.

@dberm22! How did you do that?

You should read and use

And if you have any issues with this ros package, then report your problems.

I said in my post that I tried 1.7. I updated it 2 days ago..the patch is not applied, so it doesn't work.

Can you give me a link to the patch you talking about? To my knowledge there wasn't any significant change. The problem was just the compiler optimization on the build farm. But I'm wondering if you compile pcl 1.7 yourself, why do you get a "Illegal instruction" error?

1 , I think this was all. And this shouldn't make a difference if you compile pcl1.7 yourself.

I wasn't sure if that flag was the only difference, so I didn't take the time to download the new source, edit the file, and then recompile myself. Plus, my laptop is a brand new aienware with SSE I have no idea if it'll help.

Yup, downloading the source, editing the cmake files to not include those checks, and recompiling did the job. Not sure why those flags should matter as my pcl is sse compatible, but either way, it's working.
