Being a newbie to this list, I recognize that the answer to this
might be "why would you do that?". But surely it can't be worse than
that.
Briefly put, I want to install numpy and scipy in jython (reasons
below). Running 'cd <jython distro>; jython setup.py install'
runs into errors. But installing he same distro under python works
fine. So the underlying question is: is there a way to install numpy
under jython?
Here's how I got here. The reason I would like this under jython is
wrapped up in Netbeans, Octave, Matlab and Windows 7. I've been
using Netbeans under linux for years for c++ and a bit of Java, and
the editing environment with cross referencing and syntax-directed
editing is quite good. Netbeans only presents python debugging via
jython, which makes sense. Most of the work I am doing is with
matrix algebra and I started with Octave, but while Octave is
excellent for operating on matrices, it is not good for file format
manipulations, hence for some operations I'd like to turn to python,
and if I edit under Netbeans, the debugging requires that I install
numpy under jython. At work I use a machine running fedora 16 ....
but... I travel a bit and my travel machine is a laptop running
windows 7. Therefore, Windows 7 + Netbeans + numpy + debugging
==> jython + numpy + scipy.
Here's the install problems, which occur under numpy-1.7.0b1 and
1.6.2. The first install error is in
numpy\distutils\exec_command.py, line 585, where it throws an
exception because the java exec tests are unlimited. So I comment
out those two lines, and rerun the setup.py.
The next errors are notes about features not being available because
other packages are also unavailable. I don't think this is really
getting in the way, although I could be wrong. The libraries
mentioned as missing are:
- libraries mkl,vml,guide
- libraries ptf77blas,ptcblas,atlas
- libraries lapack_atlas
So setup gets as far as this:
running install
running build
running config_cc
unifing config_cc, config, build_clib, build_ext, build commands
--compiler options
running config_fc
unifing config_fc, config, build_clib, build_ext, build commands
--fcompiler options
running build_src
build_src
building py_modules sources
creating build
creating build\src.java1.6.0_33-2.5
creating build\src.java1.6.0_33-2.5\numpy
creating build\src.java1.6.0_33-2.5\numpy\distutils
building library "npymath" sources
No module named jythoncompiler in numpy.distutils; trying from
distutils
customize GnuFCompiler
Could not locate executable g77
Could not locate executable f77
don't know how to compile Fortran code on platform 'java'
Some of these messages make it look as if the config wants to use
the cygwin gnu compilers, which are ok, but under windows are not
nearly as good as mingw gnu compiler or better yet, the visual
studio 2010 compiler. I have both, but I don't see a way to steer
the numpy setup to use them.
The next error is fatal
File "...\numpy-1.7.0b1\numpy\distutils\ccompiler.py",
line 111, in CCompiler_object_filenames
if ext not in self.src_extensions:
TypeError: 'NoneType' object is not iterable
This one looks as if it does not know what .o or .a or .obj files
are. Fixing this one looks like hours of digging through the code.
Is there a simpler solution?
Thanks in advance,
Todd
