shell script help

cpv204 · 06-11-2003, 11:46 AM

Hi, I need some help deciphering what the first line of the following code does:

Code:

PYGNOME=`python -c "from gnome.ui import *" 2>&1`
PYGNOMEEXISTS=`echo $PYGNOME|grep -i "no module"`
if test "$PYGNOMEEXISTS" != ""
then
    echo failed: get it from ftp://ftp.gnome.org/pub/GNOME/stable/latest/sources/
    exit 1
else
    echo yes
fi

I understand everything but the first line, just included the rest to give you some context. I even understand that the first line is setting the variable PYGNOME to the result of running some python script, but there are a lot of things going on in between the ` ` and I don't understand it fully.

The reason I need help on this is that it comes from the ./configure script for eroaster, which I'm trying to install. eroaster requires gnome-python to be installed. I have installed gnome-python over and over again, but whatever I'm doing doesn't satisfy this piece of code in the eroaster ./configure script.

I'm hoping that by understanding what this script is looking for I can troubleshoot why it isn't recognizing that gnome-python is installed. Thanks!

Run this from the command line and let's see the output:

python -c "from gnome.ui import *"

Yeah, I suppose that's one way to inch forward

. I'll have to do this tonight, though.

One thing I know is that if gnome.ui is a file, it doesn't exist on my system. I've done a find / -name gnome.ui and it comes up empty.

install pygnome then

Chris, I know you mean business so I will on your say-so...but...

The output on the screen while the script is running just before this error comes up says "checking for gnome-python........."

Then the error says "failed: get it..." etc. etc., so I went and ftp'd the gnome-python package.

What's the diff between gnome-python and pygnome and how am I, a worthless user, supposed to know that when the error message says get gnome-python that I should really be getting pygnome?

well the file it's actually looking for isn't gnome.ui, it's actually gnome/ui.py that's just the way python represents it. mine is here:

/usr/lib/python2.2/site-packages/gtk-1.2/gnome/ui.py

ideally the command should return nothing at all (change the original command to a blatantly incorrect module - i heartily recommend gnomebum.ui

)

pygnome IS gnome-python, sorry if i mislead you.

harrumph!

I uninstalled gnome-python, then python.

Then reinstalled python, then gnome-python. I searched for ui.py and found it in /usr/local/lib/python2.2/site-packages/gtk-1.2/gnome/ while Chris's was in /usr/lib/python2.2/.../gnome

So, I copied the contents of the /usr/local/lib/.../gnome directory over to /usr/lib/.../gnome. With this, eroaster-2.0.12 was able to configure and install.

I do have a run-time error with eroaster, but I guess I'll start another thread since this thread really concerns the deciphering of that python command.
