[pdal] PDAL 1.4 compile error

[Alex Jokela]

Andrew-

Thanks for the reply.


I game to try compiling from master.  I did run into a different compile error when I tried master earlier today.  I don’t have that error handy, though.  I’ll clone the repo, again, and will compile, if you’re interested in that error.

Let me know if you push the change you mentioned for a work around.

Thanks!
