Hi,
just to tell you that even I have full usefullness of ETS-mayavi, I have
just tried to make a test
running Chaco's demo.py, and then, I can tell you that the problem I had when
building Enable spkg
had some unwanted consequences. Such Enable diagnose at the ending of Enable's
building was:
______________________________________________________________________________________________
...
copying static files... done
dumping search index... done
dumping object inventory... done
build succeeded.
error: Setup script exited with error: SandboxViolation:
os.open('/tmp/tmpEOJpoX/d3vJvv', 131266, 384) {}
The package setup script has attempted to modify files on your system
that are not within the EasyInstall build area, and has been aborted.
This package cannot be safely installed by EasyInstall, and may not
support alternate installation locations even if you run its setup
script by hand. Please inform the package's author and the EasyInstall
maintainers to find out if a fix or workaround is available.
---------------------------------------------------------------------------------------------------------------------------------
it seems to me that Traits is working well, but running the Chaco's demo
complains with a message about some
UnboundLocalError: local variable '_mod' referenced before assignment
I have ran one of the examples (logo.py) in the demo separately, in order to
see what the catch up is
and I got the next message (I am sorry if this is an excessive detail):

So, now it's clear to me that something important was lost with that unaccepted
setup command,
could you suggest me any way to circumvent the EasyInstall problem to get a
properly working Enable installation.
Best regards,
Jorge
PS I have used swig-1.3.39 (installed at /user/local/bin)
instead of swig-1.3.31.spkg because in that case Chaco's demo complains about
two float variables (x, y in a plot) being double type which it cannot
recognize (?).
I don't know if the problem was originated also by the Enable's incomplete
building, but changing the
swig version that complaint does not appear again, although the problem is the
one I am reporting at the upper lines.

Subject: [sage-support] ETS.spkg succesfully rebuilt
Date: Sun, 9 Aug 2009 19:01:14 -0500
Hi William and Ondrej!
It was not so easy as I would like but finally I succeeded rebuilding ETS,
I have to overcome another three new issues:
1) swig.spkg had its path-library configured to:
/opt/sage-3.4.1-linux-Ubuntu_8.10-sse2-x86_64-Linux/local/share/swig/1.3.31
I solve this changing the environment variable SWIG_LIB to
/opt/sage/local/share/swig/1.3.31
2) With this all the programs in Enable were successfully built but an error
message was sent about some unreachable path to
Easyinstall:
I have just continued ignoring it.
3) The ets spkg-install then didn't complaint any more finishing the
rebuilt, but trying to run mayavi2, sage sent the message:
file
"/opt/sage/local/lib/python2.5/site-packages/wx-2.8-gtk2-unicode/wx/_core.py",
line 336 in <module>
RESERVE_SPACE_EVEN_IF_HIDDEN = core_.RESERVE_SPACE_EVEN_IF_HIDDEN
Attribute Error: 'module' object has no attribute
'RESERVE_SPACE_EVEN_IF_HIDDEN'
So, I re-install wxPython and tested it running demo.py it ran fine.
Then run again ets spkg-install
and
finally: testing mayavi2:
everything worked wonderfully.
So I am very gratefully with you for helping me with this problem.
Sincerely
Jorge
