First though, congratulations on the amazing install documentation without which I (a non-programmer) would never have got even to this point. Everything has gone according to the instructions so far - I've installed boost, cmake and laszip-1.0.1 (actually not mentioned in the documentation). The configure process has completed successfully for the base and optional libraries, but at build I get seven errors that causes build to fail - I'm trying to build lasinfo, as directed.

We want to make sure that platform works, as it is a rapidly improving up-and-comer, but it might still lag a little bit due to cultural uptake from the project.

OK -- that did the trick. With Xcode 3.2.5 no errors (but 150 warnings .....)
I did have to start from scratch; when I tried to compile my existing project I got the old errors
One other thing for those compiling on OS X using the instructions at:
http://liblas.org/compilation.html#using-xcode-on-os-x
The arguments to be passed on at launch for the test of lasinfo had to be changed
First I get an error message:
Program loaded.
run
[Switching to process 31225]
Running…
error: unknown option -c
I unchecked the "-c" in the set up box, and the error went away
then:
Debugger stopped.
Cannot open /Users/stu/liblas/test/data/TO_core_last_zoom.las for read. Exiting...
This is because the file is actually /test/data/TO_core_last_clip.las in my download
So change this too in the set up box and it should run just fine.............
Thanks for the help
Stu
