I'm trying to build Moar from the latest on GitHub and the download on MoarVM.org. I keep getting an error about third-party libraries:
ld: warning: ld: warning: ld: warning: ignoring file 3rdparty/libatomic_ops/src/libatomic_ops.a, file was built for archive which is not the architecture being linked (x86_64): 3rdparty/libatomic_ops/src/libatomic_ops.aignoring file 3rdparty/tinymt/libtinymt.a, file was built for archive which is not the architecture being linked (x86_64): 3rdparty/tinymt/libtinymt.aignoring file 3rdparty/sha1/libsha1.a, file was built for archive which is not the architecture being linked (x86_64): 3rdparty/sha1/libsha1.a
This is similar to OSX : File was built for archive which is not the architecture being linked (i386) (and many other questions with insufficient answers). I know that something is building these for the wrong architecture already, so please skip providing that answer.
I've cleaned the directories, deleted everything and started over, told Configure.pl that I'm running on Darwin, and the various other things a user should know to do. I downloaded the tarball from MoarVM.org, which should be the 2105.12 tag in the repo. I run into the same issue with rakudobrew.
Let me know what you'd like to know about my system; it's a basic Mac OS X setup.
I've also filed this as MoarVM issue 334, but it looks like the issue queue doesn't get a lot of love.
