[SciPy-dev] SciPy SELinux and import bugs?
Wed Sep 26 12:52:16 CDT 2007
I've just "upgraded" to RHEL 5 and am going through the chore of
installing a ton of software that I previously used under Fedora,
I've gotten numpy-126.96.36.199 installed (with atlas & fftw) and it passes
all tests. But with scipy-0.6.0, scipy.test(1,1) gives me an
"Illegal instruction" error, and crashes out of Python. The first
such error was an SELinux violation due to a text relocation
requirement in _fftpack.so (whatever that means!). I executed
the "chcon" context change command SELinux suggested as a workaround.
But scipy.test(1,1) still crashes with "Illegal instruction" at
apparently the same place, though now without raising an SELinux
violation (at least, not one that appears in the SELinux troubleshooter).
At this point I thought I'd give the current SVN SciPy (r3369) a try.
It installs fine, but I get an error on import:
>>> import scipy
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.5/site-packages/scipy/__init__.py", line 63, in <module>

def factrl(n, ntop=0, prev=N.ones((33),N.Float)):
AttributeError: 'module' object has no attribute 'Float'
It is finding an old script of mine that happens to be named "special"
that I haven't used and thus haven't upgraded from Numeric to NumPy.
But that's beside the point---I think it must be a bug that SciPy's
import mechanism is finding it.
Any suggestions for dealing with either issue (Illegal instruction
with 0.6.0, or the import issue for r3369) would be appreciated!
PS: Regarding the text relocation issue in _fftpack.so, SELinux
points to this web page for hints on how to fix it:
