Hi all,
I am using OS X 10.10 Yosemite.
I was beta-testing it since July, and failing to build Sage.
(Strangely I never thought about using the OSX-10.9 version.
I just tried and it works! Thanks Stefan for asking the
question, and Volker for answering it works!)
About building Sage on Yosemite, here is my experience.
- While beta-testing Yosemite, I tried to build Sage 6.3.
My report on sage-release [1] has links to a few log files.
- Incidentally I asked on sage-devel [2] about the Sage project
getting developer previews of future versions of OS X.
- Having understood that the bug was with gcc, I then installed
homebrew, and used it to install gcc 4.9.1, hoping this would
help building Sage, but that failed at a further step, which
I reported on sage-release [3] where Volker helped to point
the failure to a specific header:
"""
That header is Objective-C, which should never have been
included when compiling C sources. Most likely an OSX bug.
You can send them a bug report if you like talking at walls...
"""
- I don't mind talking at walls and I wanted to report to Apple
with some details, but I thought I should first make sure this
was not a homebrew thing, so I emailed the homebrew list [4]
and someone answered [5] suggesting an experiment (not done).
- I have now installed the finalized version of Yosemite, and
I still have Apple's "Feedback Assistant" from beta-testing.
(Plus, Apple tells me I will get betas of the next releases.)
So I would love to send feedback to Apple about this issue, but
I'm unsure how to formulate the issue, could someone help here?
One option would be to point to this thread, but maybe a
concise description of the issue would have more chances
of being dealt with?
