MoarVM will not compile on 10.6.8 Snow Leopard

[drennanelawar (Daniel Drennan ElAwar)]

I get the following when trying to install MoarVM:

I'm unable to reproduce the problem and the port built ok on the 10.6 buildbot as well.

Maybe a different volume has something to do with it, but I don't know why that would be the case. Maybe you can try to clean the build and then run

sudo port -v install MoarVM configure.compiler=macports-clang-3.4

just in case that one works better.

Thanks for the quick response. I tried your more specific command, with no success....

New log attached.

[mojca (Mojca Miklavec)]

Can you please ask upstream for help with your issue? They are accessible via IRC channel #moarvm, their bug tracker is at ​https://github.com/MoarVM/MoarVM/issues. I could ask them, but if I'm unable to reproduce the problem, I cannot provide feedback when they ask me further questions.

I just built it as well, on 10.6.8 (this system is set up with LibcxxOnOlderSystems and default compiler=macports-clang-3.9).

$ port -v installed moarvm
The following ports are currently installed:
  MoarVM @2017.05_0 (active) platform='darwin 10' archs='x86_64' date='2017-05-30T23:13:42-0700'

Your missing symbols should be defined and built in src/profiler/telemeh.c. Check your telemeh.o object file and see what it contains.

I'll enclose a log from a debug build here so you can compare to yours. It's not immediately obvious to me what is wrong, though.

[drennanelawar (Daniel Drennan ElAwar)]

Well, I apologize for the effort on your part as much as I thank you for it. I followed the instructions I found concerning Using libc++ on older systems and this has fixed the issue.

must have been something specific on your system -- at any rate, glad it works now~
