Numeric compiling problem under QNX 4.25

[ZMY]

Dear all,

I am a real newbie for both python and QNX, but I am still trying to
compile Numeric-24.2 under QNX4.25 with python 2.2. I got following
error message:
$ sudo python setup.py install
Password:
running install
....

skipping Src/_numpymodule.c (build/temp.qnx-O-PCI-2.2/_numpymodule.o
up-to-date)

O-PCI-2.2/_numpy.so
unable to execute ld: No such file or directory
error: command 'ld' failed with exit status 1

I looked at directory /build/temp.qnx-O-PCI-2.2/ and found following
object files:

_numpymodule.o, arrayobject.o, ufuncobject.o

So it looks that ld got all files before linking them - or is it??

Thanks a lot for any suggestions,

Hi,

unfortunately I don't have a solution. However, if you're not forced
to use Python2.2 and Numeric you should use Numpy (the successor for
both, Numeric and Numarray). Numpy requires Python2.3, though.

He's already asked about numpy. He is stuck with 2.2.

It looks like it can't find the command ld. Can you compile any other extension
modules?

Is "ld" part of make command? I am not familiar with compiling with
make in general.

Most other extensions (including math, os, struct, cPickle) from
Python 2.2 works when I install python on QNX.

Thanks a lot to all of you.

No, it's the linker. I takes the object files (.o) which are generated by the
compiler (cc, I imagine) and links them together into the shared library (.so).
make is a program that can automate builds given instructions, but Numeric
doesn't use it, nor do most other Python packages.

No, I was wondering if you could build any other third-party extension modules.
Did you install Python from source? When building extension modules, Python uses
whatever linker was used to build itself.

If you're new to QNX, why are you running QNX 4? That's for legacy
systems only. Move up to QNX 6, which has been out for ten years now.

Dear Robert,

Looks like you are right. Here is what I got when I compile the
Python2.2 from source (or I believe so):

.....

If there is no 'ld' linker, what should be used instead??

BTW, the reason I am still using QNX4.25 is because I was trying to
install python on this legacy system. We can't move to QNX6 unless we
want to redo all other code as well, which took 3 years of a good
programmer :-(

I have tried to use Watcom linker 'wlink' in QNX instead of the 'ld'
linker, but I still got problem with _numpymodule.o

Do you have any experience with this??

I don't know. I've never used QNX. It looks like the Python binaries were built
with a linker that you don't have on your system. Usually, you have to use the
same compiler/linker combination to build extension modules that you used to
build Python itself.
