Last week was a pretty annoying week for Solaris support. Two
quite major
obstacles came up.
1) #7932: _Complex_I undeclared - a new bug totally stops a
Solaris 10
build.
has introduced code which exploits a bug in gcc, which stops Sage
building
on Solaris. This was particularly annoying, as 4.3.1 was expected
to be the
first version to build easily on Solaris. But that rather put a
stop to
that.
I notice Robert has included what he concedes is a 'hack' to
disable the
code. I I've not bothered reviewing that yet, as there may be
other ways
around this issue.
Robert explained this fix to us yesterday at Sage Days and it sounded
pretty reasonable to me.
The hack doesn't disable this code, it unsets then resets _Complex_I
to the complex literal 1j if both __GNUC__ and __sun__ are set.
I'm just trying that now. The URL Robert gave on the ticket
http://sage/home/robertwb/cython/cython-0.12.p1
is invalid, though I think I'm managed to work out what he means.
I've managed to find something called cython-0.12.p1.spkg
Yep. It seemed to fix the build on t2. (If we're going to ship the
patched spkg, it think I'll have to clear out some build files in
there.) I'll be incorporating this into the next release of Cython.
In any case, keep up the good work. We're certainly getting close...
