Description
See #13313 and the comments at the end of #16455. Basically, a patch was removed that allows pyzmq to build on old (32-bit) Macs - the problem is that pyzmq assumes one has the Mac version of gcc which supports the -arch flag, which we do not since we build our own vanilla gcc.

comment:2 Changed 6 years ago by
On my osx 10.5.8, with Sage Version 6.4 that I compiled without problem, I get this:
sage: import platform
sage: platform.architecture()
('32bit', '')
Also, I do not use the SAGE64='yes' flag.
Here is my (stripped) log of sage -f pyzmq :
$ sage -f pyzmq

Very interesting. I wonder why it is that you don't have trouble? In principle, I don't think gcc in Sage should support that -arch flag. I also note your computer is Intel, not PPC chip, though the code of the patch shouldn't really care. Huh.

- Status changed from new to needs_info
I've given up now on this (see #17513) but not sure if this is relevant beyond PPC or 10.4 Macs. Sebastien, if you are able to still build on that computer I think we could close this as wontfix.
comment:8 Changed 5 years ago by
I can't tell as I upgraded my old mac 10.5.8 to 10.10 and pyzmq installs on 10.10 with no problems.
Before upgrading to 10.10, I verified (comment:2 above) that pyzmq was able to install on 10.5.8. That was the reason why I suggested in #16455 to remove the patch that I had written in #13313 to fix the pyzmq install issue on 10.5.8. So to me the patch was (possibly) relevant only for PPC or 10.4 but I can not confirm as I do not have access to such a machine.

Note: See
TracTickets for help on using
tickets.
To be more precise, it is the output of Python's
platform.architecture()that pyzmq uses, so perhaps some 32-bit Macs are immune, if they build a 64-bit Sage.
