Failed install with MacOS 10.14.3

[mcmessina]

Hi,

I am following the guide to install on MacOS with version 10.14.3. The install is having trouble finding one of the standard libraries and I am unable to find a solution. Could this be an issue with Xcode 10 that is related to this thread?

I installed PCL from homebrew with:

brew tap brewsci/science
brew install pcl

My error occurs here (running Python 3.5.4):

Thank you!

Took a little while, but I found a workaround:

In setup.py, add the following lines for extra compile arguments (at roughly line 580) and extra linker arguments (at roughly line 610).

ext_args['extra_compile_args'].append("-stdlib=libc++")
ext_args['extra_link_args'].append("-stdlib=libc++")

Then, in terminal:

export MACOSX_DEPLOYMENT_TARGET=10.10

I will not close the issue myself in case this inspires changes to the setup.py file or build instructions for Mac.

Cheers!
