Hi Sean,

This is a known issue and fixing it will require a fix in our form of rockstsar. I’m personally unsure how to fix it. See https://github.com/yt-project/yt/issues/1289

If you have any idea how to modify rockstar to fix this that would be very much appreciated.

If you build on Linux you will likely not hit this issue.

I have been trying to install Rockstar with yt onto a computer running macOS sierra 10.12, using both the install script and manually.

For the install script, I get this error:

Failure.  Check /Users/user1/Rockstar/yt-conda/yt_install.log.  The last 10 lines are above.

And when installing manually, after stating "make lib" i get this error:

I am not sure what is causing the error for install script, but for the manual install, I think it is clang using the wrong c++ standard library. I have attempted to change the library used, but nothing has worked for me so far.
