[Numpy-discussion] Merged clean_math_config branch
Hi there, Just to mention that I merged back my changes from the clean_math_config branch into trunk. The main point of the branch is to clean our math configuration. If this causes problems, please report it. I built and tested on mac os x, linux 32 bits and windows (both mingw32 and VS 2003). It breaks windows 64 bits ATM, but this will be fixed soon. The numscons built is broken as well, but the missing features are already backported from numpy.distutils to numscons; a new working version of numscons is about to be released. Some details for the record: - more code is platform independent, with platform specifics math functions at one location - instead of platform-specific heuristics, every function is tested at the configuration stage. Some distutils.command.config functionalities were improved to make this process as fast as before for relatively standard-compliant platforms (mac os X and linux are as fast to build as before). - the distutils.command.config.check_func can now detect MS intrinsics (functions which are not visible without optimization flags). - should also be more robust for non standard platforms (MS compilers, mostly). In the process, a few hundred lines of C code have been removed. cheers, David ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
Re: [Numpy-discussion] cannot find numpy 1.2 for python 2.6 on window
Hi Alan, I've been using numpy with 2.6 on amd64 for about 3 months no problem and far more stable on 64-bit than the same combination with 2.5. Daniel, just download the source and compile it yourself. You need to use VS 9.0 for best compatibility with Python and I haven't yet sorted out fast blas I've just been using the internal numpy one.

[Numpy-discussion] asscalar(number) - why yields error, why can't return the number?!
hi all, I wonder why numpy.asscalar(1.5) yields error, why it can't just return 1.5? Is it intended to be ever changed? numpy.__version__ '1.3.0.dev5864' D. ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion

Re: [Numpy-discussion] cannot find numpy 1.2 for python 2.6 on window
Hi David,
Yeah nose was an issue, thanks for letting me know about nose compatibility
being sorted that's good news as I use it a bit with my testing.
I last built 1.1.1 with express for 32bit it went fine (although I think you
do have to comment out , I was also able to compile with 2008 full for
64-bit platform, my next goal is to see if i can sort out blas etc. external
libs on 64bit.
From the Installation info thread around the 30th May I had reported the
one oddity I had encountered with the VS compiler
In order to get numpy to compile I
have commented out a small part which was causing compilation to fail:
numpy\core\src\umathmodule.c.src(64) : error C2059: syntax error : 'type'
numpy\core\src\umathmodule.c.src(70) : error C2059: syntax error : 'type'
This relates to this section of code:
#ifndef HAVE_FREXPF
static float frexpf(float x, int * i)
{
return (float)frexp((double)(x), i);
}
#endif
#ifndef HAVE_LDEXPF
static float ldexpf(float x, int i)
{
return (float)ldexp((double)(x), i);
}
#endif
At the time I had tried to send further output following a checkout, but
couldn't get it to post to the list, I think the message was too big or
something. I will probably be having a go with 1.2.0, when I get some time.
I'll let you know how it goes.
Cheers,
Hanni

That's the major difficulty: no open source blas/lapack (that I am aware
of) are buildable with MS compilers, and there is no official open
source compiler (mingw) on 64 bits. Also, cygwin itself is not available
in 64 bits (only available on WOW, the windows subsystem to run 32 bits
on 64 bits OS).
Atlas, in particular, is not buildable for 64 bits windows AFAIK.

I did some heavy refactoring for the above problems, and it should be
now easier to handle (in the trunk). I could build 1.2.0 with VS 2008
express on 32 bits (wo blas/lapack), and there are some test errors -
albeit relatively minor at first sight. I have not tried on 64 bits.

David

[Numpy-discussion] Please backport fixes to the 1.2.x branch
Hello, I would like to get a 1.2.1 release out ASAP. There are several bug-fixes on the trunk that need to be backported. If you have made a bug-fix to the trunk that you have been waiting to backport to the 1.2.x branch, please do so now: http://svn.scipy.org/svn/numpy/branches/1.2.x Ideally, I would like to freeze the branch for the 1.2.1 release in about 1 week. Please let me know if you need more time or if there is something in particular that you would like to see backported.
