[Bitpim-devel] wxPython instructions for Debian?

[Mike Schiraldi]

If there's anyone on this list who runs Debian and was able to get wxPython
installed in such a way that BitPim can be run from CVS -- and remembers how
they did it -- could you take a look at what i did (detailed at
http://schiraldi.org/bitpim-cvs-howto.html) and tell me what you did
differently?

As i've mentioned in an earlier message, i get stuck at the following
exception:

Traceback (most recent call last):
File "bp.py", line 93, in ?
import gui
File "/tmp/bitpim/gui.py", line 23, in ?
import wx
File "/opt/wx/2.5.2.8/wxPython/wx/__init__.py", line 42, in ?
from wx._core import *
File "/opt/wx/2.5.2.8/wxPython/wx/_core.py", line 4, in ?
import _core_
ImportError: /opt/wx/2.5.2.8/wxPython/wx/_core_.so: undefined symbol:
_ZN5wxApp10InitializeERiPPw

I've determined that it actually is missing all of the following symbols:

_ZN5wxApp10InitializeERiPPw
_ZN12wxStringBase10ConcatSelfEjPKwj
_ZN12wxStringBaseaSEPKw
_ZN12wxStringHash16wxCharStringHashEPKw
_ZN8wxString6PrintfEPKwz
_ZN12wxStringBase8InitWithEPKwjj

Those symbols are defined by an object file which, on my system, is located
at /opt/wx/2.5.2.8/lib/libwx_gtk2u_core-2.5.so. Was this supposed to be part
of my wxPython installation?

I tried export LD_PRELOAD=/opt/wx/2.5.2.8/lib/libwx_gtk2u_core-2.5.so, but
then i ended up with:

python: relocation error: /opt/wx/2.5.2.8/lib/libwx_gtk2u_core-2.5.so:

Here is how I did it.

# apt-get install alien
# apt-get install libgtk2.0-dev freeglut3-dev python2.3-dev
# wget http://voxel.dl.sourceforge.net/wxpython/wxPythonGTK2-py2.3-2.5.2.8-1.src.rpm
# rpmbuild --rebuild wxPythonGTK2-py2.3-2.5.2.8-1.src.rpm
# cd /usr/src/rpm/RPMS/i386
# alien *py2.3*
# dpkg -i *py2.3*.deb

wxPython builds perfectly and BitPim works fine if you do that.

Worked great. I've added that to my HOWTOs -- if any other Debian users are
having trouble getting things to work, you can point them to the URLs i've
posted earlier.

I hate to say it, though (because i've seen bitpim-user-no-support.htm), but
i'm having trouble getting the CVS version of BitPim to find my phone. The
RPM version finds it, though. And it's not a matter of code: I even tried
"cvs up -d -r BITPIM_0_7_17" to get my CVS tree to match the codebase used
in my RPM. RPM works, CVS doesn't. I can run one, then the other, going back
and forth without unplugging the phone, and it's the same results each time.

The phone's at /proc/bus/usb/001/013. When i run the RPM version of BitPim,
i see:

===== Available Ports =====
USB Device - Vendor LG Electronics Product VX 4400/4500/4600/6000 Phone
(Interface Diagnostics Interface)
[...]

...and when i select it, it puts usb::001::013::2 in the textbox and i can
browse my phone's file system. But when i run the CVS version, even as root,
i just see:

Automatic
===== Inoperable Ports =====
USB to serial convertor (/dev/ttyUSB0)
USB to serial convertor (/dev/ttyUSB1)
[...]
USB to serial convertor (/dev/ttyUSB9)

If i select "Automatic", it says it can't find a usable port.


Since i know these kinds of problems are hard to debug, and people post
about them to the list all the time, i understand if nobody has time to help
me out with this.. at least now i can run the code, so i can start adding
debug statements and such. But if anyone has any tips, i'd love to hear
them.

Not in this case. Go to

Read the bit titled "Build usb library (optional)"

I'm happy to say that i've now got both the RPM and CVS versions of BitPim
working on my Debian-testing box. If anyone is having trouble with this
specific OS, feel free to contact me for info.

Additionally, the weird bug i was having (where right-clicking on direcories
showed the regular-file context menu) isn't present in the current CVS.

For a while, i was having problems backing up my entire directory tree -- my
CPU would go up to 100%, and after about 180 of 330 files, my throughput
would drop to about 10 bits/sec. I realized this was because i had Protocol
Logging on; turning this off made everything work great. Maybe a warning
should pop up if a user tries to do a full backup with Protocol Logging on
(or a backup of more than n files)

So now i'm getting started figuring out how to add support for my phone, the
LG VX-7000. If there's anyone else interested in participating, let me know.

my throughput would drop to about 10 bits/sec. I realized this was
because i had Protocol Logging on; turning this off made everything
work great. Maybe a warning should pop up if a user tries to do a
full backup with Protocol Logging on (or a backup of more than n
files)

I don't have any intention of protecting users from themselves,
except in the default settings. ie the defaults should be sane
and sensible.

Protocol logging is off by default. The help page explicitly says:

http://bitpim.org/testhelp/tab-protocollog.htm

This tab contains detailed information on all data sent to and
received from your phone. It is off by default and needs to be
turned on in the View menu.

This will consume vast amounts of memory and slow your machine down,
so only use it for low level debugging purposes.

The real reason why there is a problem is because the underlying
GTK widget doesn't actually support an AppendText method. What
wxWidgets actually ends up doing is getting the current contents,
adding the new text and then reparsing to find each end of line.
This takes exponentially more time as the contents get larger.

So now i'm getting started figuring out how to add support for my
phone, the LG VX-7000. If there's anyone else interested in
participating, let me know.

Your first step is to make one phonebook entry with every field
set to its maximum length value and get BitPim to read that one
entry (set the phone to be a VX4400). On the other LG phones you
can actually make a backup of the pim directory, clean out all
files in there and reboot the phone. Then do experiments and when
you are finished restore the backup and reboot.

Once you have the one entry dumped, post the hex to this group.

Before wiping out any data (even though i do have it all backed up now), i
thought i'd give it a try with my current phone book. I set my phone type to
4400 and did a Get Phone Data with just "PhoneBook" selected. I got the
following exception. Was that because i didn't follow your directions -- do
you expect it will work if i have just one maxed-out entry in my phonebook?

I could just use the Filesystem browser to back up the files and hexdump
them, right?

Nope, it is because the phonebook entry data structure is different
on almost every model of LG phone. BitPim will fall over on the
very first one. That is why you need to have only one entry and
for that entry to have the maximum sizes on all fields. Turn
on the protocol logging first.

Email the last packet in the log.

Nope. We don't access the raw files. We use the LG phonebook
protocol. Run the analyser on examples/vx4400phonebookread.txt
to get an idea of what it should look like.
