Hi, I'm running a python script which if I run from the command line
as root runs fine. But if I run it through the web-browser as a cgi
script gives the following error "Error in X11: unable to start device
PNG".
Now I should say that this python script is calling fucntions in R (a
scripting languange used in statistics) using the python module RPy,
so this I dunno if this is entirely a Python question, because as far
as I can see the error is being thrown by R. But then as I say, when
the script is run by the root user from the command line everything
goes off without a hitch.
So I dunno is there some way to run a CGI script as root, maybe thats
a bad idea because of security? But any ideas would be welcome.
-Thanks.

Ah, but does it run if you boot into a NON-graphical command shell
mode...
That error message looks suspiciously like something is trying to
open a graphical display window... A web-server likely does not have any
graphical environment.

Ya thanks looks like you're actually right. The strange thing is that
the program, when run from a graphical command line, doesn't actually
open any display window. Although the code doesn't run when executed
as a webserver, most likely, as you pointed out, because there is no
graphical environment. I wonder if there any way I can somehow enable
a graphical environment for the webserver, or do I have to re-write
the underlying code? This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Hi,
I've written a script to run on windows to extract all zips under a
given directory path to another directory path as such:
python extractzips.py <fetch all zips under this dir> <put all extracted

The purpose of this script is to retrieve backup files which are
individually zipped under a backup directory tree on a backup server.

I'm trying to use the py-gnuplot module on windows, and have
been unable to get it to work reliably under Win2K and WinXP.
By default, it uses popen(gnuplotcmd,'w'), but in some
situations that consistently gets an "invalid operand" IOError
when write() is called on the pipe.
So I switched to subprocess. It works fine when executed
"normally" (e.g. "python progname.py"), but when bundled by
py2exe, it always does this:

I believe this bug is also related to the other problem I just reported.
OS = Windows XP SP2
DB = Microsoft Access XP
PROBLEM:
When you use + (or &) to concatenation columns together and the columns are
of type text and the combined length exceed 255 this causes pyodbc to fail
and python to crash.

I have a code that writes to 2 seperate files. I keep getting a "list
index out of range" error. The strange part is that when checking the
files that I'm writing too, the script has already iterated through
and finished writing, yet the error stated implies that it hasn't? So
how can it be, that my script has written to the files, yet the error
is stating that it hasn't made it through the script? I'll have 15

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
