Hi,
when compiling numpy-1.40 with the Sun Studio Compilers (v12 Update 1) on Linux
(an OpenSUSE 11.1 in my case), about 30 tests in numpy.test() fail; all
failures are related to the arctan2 function.
I've found that in r7732 a patch was applied to
trunk/numpy/core/src/private/npy_config.h i
Hi,
I've been carrying these modifcations of the build-in compiler
command line arguments for the 32-bit Intel compilers for quite
some while now; maybe they are interesting for other people as
well... I've been using this with ifort (IFORT) 10.1 20080801
on a Suse Linux 10.3.

They are, also in v1..3.0rc1
Many thanks!

seem recognize
other packages which are only available there (e.g., scipy or netCDF4 if
specified as a requirement for the install... strange. It also doesn't seem
to work for tables (2.1, so not the newest version)).
Any ideas on what might be going on?
Thanks a lot,

the .src files converted?
Many thanks,

I ran into the following problem:

Hi,
I think the default for the standard python distutils is to use the
compiler and the compiler settings for the C compiler that were used to
build Python itself. There might be ways to specify other compilers; but
if you have a shared python library build with one compiler and modules

Restore the invariant, and follow python.

all basic operators provide you with the same same answer when

Actually,
it happens for normal integers as well:

Dear all,

Yeah. Especially as it works apparently fine for uint32 and int64.

Hello,
The following is what I expected...
>>> y = 1234
>>> x = array([1], dtype = "uint64")
>>> print x + y, (x + y).dtype.type
[1235]
but is this the way it should be? (numpy 1.0.2, Linux, Intel comilers)
>>> print x[0] + y, type(x[0] + y)
1235.0
Thanks,
Christian.

Yes,
that worked - many thanks!

Sun has recently released their compilers under an opensource license for
Linux as well (Sun Studio Express or something), including their perflib -
which includes Blas and Lapack. Has somebody tried how that combination

I've run into a problem building numpy-1.0.2 on AIX (using gcc and native
Fortran compilers). The problem on that platform in general is that the
process for building shared libraries is different from what's normally

a) Don't know; the last releases of pycdf and pyhdf are

adapted to the location of the actual HDF libraries and headers.

Dear list,
attached is a patch for the original pycdf-0.6.2-rc1 distribution as
available through sourceforge - and a little shell script illustrating
how to install it. After applyng the patch, it should be configured for
numpy. Note that the "installation" script uses an environment variable

Dear rex,
I'll try to explain... I hope it's not too basic.
Python is searching for its modules along the PYTHONPATH, i.e. a list
of directories where it expects to find whatever it needs. This is the
same as the Unix shell (or the DOC command.com) is looking in the PATH in

to find programs
