PDAL: Can't read compressed file without LASzip or LAZperf decompression library.

[garthk]

Is there some way to have the pdal formula use the laszip formula?

$ brew install pdal laszip
Warning: pdal-1.1.0 already installed
Warning: laszip-2.2.0 already installed
$ pdal info points.laz
PDAL: Can't read compressed file without LASzip or LAZperf decompression library.

Could try just adding a depends_on "laszip" => :optional or :recommended if it's a small and important dependency.

[garthk]

I don't believe that's sufficient: pdal doesn't pick up that laszip is available.

[MikeMcQuaid]

Could you try and open a pull request? That'll make this easier to debug. This document should help and I'm happy to walk you through anything else.

I suspect it also may need a cmake argument.

Thanks!

Note for those arriving here via Google: brew install laszip pdal won't give you a PDAL with LASzip support. The CI-brewed bottles for pdal don't include laszip because it's optional, thus not present at compile time.

The correct installation procedure for LASzip support is: brew install laszip && brew install --with-laszip pdal

$ brew install laszip
Warning: laszip-2.2.0 already installed

Thanks for the formula patch, @DomT4!

The correct installation procedure for LASzip support is: brew install laszip && brew install --with-laszip pdal

If you just do brew install pdal --with-laszip it'll grab the dependency for you if you need it. No need to preempt it unless you particularly wish to.

Thanks for the formula patch

No worries! 😺

Sorry to open this up but one key process on my work flow does not seemed to work? On Mac OS El Capitan the above seemed not to cut it?

[DomT4]

As @garthk noted, you'll need to brew reinstall pdal --with-laszip.

I figured out that I uninstalled the pdal and laszip then reinstall them back now its working sorry for the panic button!
