[pdal] PDAL 1.4 compile error

[Adam Steer]

Alex, all

What OS are you using? For what it’s worth I went through similar issues building PDAL a while back on centOS 6. I got around it using devtoolset-4, which gave me newer compilers and ccmake3:

This was a hacky ‘gotta get it going’ solution, but it worked. Migrating to centOS 7 removed the need to use the devtoolset.
