That's the error I get. When trying to run a java app with the firefox plugin, the browser simply crashes if it's the 64bit java or tells me it's not installed if it's the 32bit version.
I'm at a loss as to what to do. I think it has something to do with leftover gunk from a previous version I misinstalled(Is that even a word?) Anyway, the only thing that google could come up with was a solution for windows which laid blame on Bill Gates for having a bunch of pf (java prefetch) files stuffed into c:windows for no apparent reason. The solution was to delete them, but I can't seem to find the java prefetch folder in linux. The method I used is downloading the rpm from java.com the rpm2tgz then installpkg then cp libnpjp2.so to firefox plugins folder.
This is my first post and I'm pretty new on Debian. I had used Ubunu for a while now and I've decided to move on Debian Squeeze.But I've one problem: I've a Java programm to install and the installer is GUI Java based. When I run the script, I've the next message:
Preparing to install. Extracting the JRE from the installer archive.Unpacking the JRE.Extracting the installation resources from the installer archive.Configuring the installer for this system's environment.Launching installer Graphical installers are not supported by the VM. The console mode will be used instead. Preparing CONSOLE Mode Installation. But this program is not able to run the installation in console mode.
I've tried to install sun-java6-jre but without success.Has anyone an idea to help me install this programm? My Configuration: Debian Squeeze 6.0 amd64.
If you are interested, Java SE 6 Update 24 is available. The Check Java Version link in my signature will tell you if you are up to date or not. The Update Java Version link in my signature will tell you how to obtain and install the latest version. The 32 bit version install directions are on the left side of that page and the 64 bit instructions are on the right side.
Just remember to remove the current version before installing the new one as it says in the instructions. The remove instructions are below the install instructions. Also, in Step 9 - "Now you'll want to tell the system, that there's a new Java version available." See the note below it that says if you get an error upon entering the command once, enter it a second time. I have to do that and sometimes forget. Just thought I would mention that. These instructions are already setup for version 6 update 24, but they can be modified for any update and they will work. I have been using these instructions for a couple of years and they work.
Due to this problem, everything that uses python is not working.

Please install a package which provides this module, or verify that the module is installed correctly.It's possible that the above module doesn't match the current version of Python, which is: 2.6.2 (r262:71600, Aug 21 2009, 12:22:21) [GCC 4.4.1 20090818 (Red Hat 4.4.1-6)]
I'm trying to write a script in python to extract data from maillogs in gz format. I wrote a shell script but i now want to do this in python, as thats the preferred method where i work. anyway does anyone know how to specify directory paths for example the maillogs exist in /var/log so i want the script to go to that directory would LOG_DIR="/var/log/" work?
View 1 Replies View RelatedI am using ubuntu hardy and python 2.6.5 (built from sources). For a custom python packager I need to rebuild python interpreter (python executable). I am new to linux and don't have much knowledge of gcc and other stuff. Here is the process:1. Copy python.c as myapp.c. myapp.c is in the same directory (python2.6.5) in which I have all the required files. 2. Using the syntax from makefile of python sources, here is my first command to produce myapp.o
Code:
gcc -pthread -c -fno-strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I/home/zeno/installed/Python-2.6.5/Include -fPIC -DPy_BUILD_CORE -c myapp.c -o myapp.o
This produce myapp.o but throws a warning:
Code:
myapp.c:24:2: warning: no newline at end of file
Next is to produce the executable or python interpreter:
Code:
gcc -pthread -Xlinker -export-dynamic -o $@ myapp.o -L. -lpython2.6 -lpthread -ldl -lutil -lm -o myapp
This is causing an error:
Code:
/usr/lib/gcc/i486-linux-gnu/4.2.4/../../../../lib/crt1.o: In function `_start':

How do you get correct ethernet/mac id of your local network card using python script? Most of the article suggests to parse the output of ipconfig /all on windows and ifconfig on linux. I am sure that this solution would work on windows but I am a linux starter and not sure the reliability of ifconfig on linux distros. Couple of other solutions on linux are:
Code:
def getHwAddr(ifname):
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
info = fcntl.ioctl(s.fileno(), 0x8927, struct.pack('256s', ifname[:15]))
return ''.join(['%02x:' % ord(char) for char in info[18:24]])[:-1]

Any tips/pointer/guide on what to do?
He was having problems with python and python-devel complaining about conflicting versions or some such when he was updating with yum. I told him (yes, a little of this is my fault) to try removing and reinstalling python and/or python-devel. Little did I know... He ran "yum remove python" and it listed over 600 (!) dependent packages to remove as well. Without telling me THAT part he clicked "y" and then watched as yum removed python and all sorts of other stuff (including yum--how's that for irony?) .
I have to go deal with this situation tomorrow morning but he has so blown away this system I almost don't know where to start. Sure I could re-download the rpm of python and reinstall, it but then I'd still have to one-by-one reinstall all the other rpms that were blown away by the python removal with yum. I do take at least partial responsibility for this. But really? 600+ packages and he clicked "y"? Yeesh. Oh, it's a RHEL 5 machine.
