I put an SD card in a reader, got all the right signs from the kernel (SCSI device: sda; write-through; etc.)including its 2GB size.
When I try to mount /dev/sda1 I get 'floating point exception' as a response, and it won't mount.
I've never had that message returned from mount, and I can't find any reference to it.
Over the last few months there have been multiple updates and I am getting a list of things that no longer work or that cause my system to fail. I can no longer open a pdf in firefox. It says there is no application assigned to the task. I ran evince and tried to open a pdf file and received a "floating point" error message on the terminal screen I was working from.

pidgin started crashing today for no apparent reason. It just shutdowns. No freezing or anything, it just goes away, disappears. From what I can say, there's no specific trigger for this, it can happen after 2 or 10 min after I started it. Once it even shutdown right 10seconds. I tried to run it from the terminal. When I do that, the only thing that appears before closing is

View 4 Replies View RelatedI know it is wrong to use the "==" operator to compare the equality of two floating point numbers. Logically it would seem that if the "==" operator is not usable for floating point comparison, then the "<=" operator would also not be usable. Is this true? The lack of google search results on this topic made me think that it must be true. If that is true, then is it true that the only way to compare floats with <= or >= is with something like the code below? Code: bool smaller_than_or_equal(float a, float b) {
if ( fabs(a-b) < EPSILON){return true;}
else if (a < b) {return true;}
else {return false;}
} I think this is a general question, but if specifics are necessary, I am using the C++ language to code at the moment.

I am using a gateway server, 1st NIC eth0 which is acting as WAN (DHCP)and 2nd NIC acting LAN(static). I am using DHCP to assign IP to eth0 from a Wimax modem. I am also use it as a MAIL server (openmail), and as a DHCP server. My server is of RHEL and kernel version is 2.4.8.18-14 and DHCP client & server version - 30pl1-9. The prolem is whenever I run the command..
ifup eth0
getting the error...
Determining IP information for eth0.../ifup: line277: 23328 Floating point exception/sbin/dhclient ${DHCLIENTARGS} ${DEVICE}
so what should I do?? if I update the DHCP, would it be ok?
I'm reading a book on assembly, and it talks a bit about the IEEE floating point format.
Quote:
To summarize, the following steps are used to convert a decimal number to IEEE single format: 1. The leading bit of the floating point format is 0 for a positive number and 1 for a negative number. 2. Write the unsigned number in binary. 3. Write the binary number in binary scientific notation f23.f22 ... f0 2^e, where f23 = 1. There are 24 fraction bits, but it is not necessary to write trailing 0's. 4. Add a bias of 127 to the exponent e. This sum, in binary form, is the next 8 bits of the answer, following the sign bit. (Adding a bias is an alternative to storing the exponent as a signed number.) 5. The fraction bits f22f21 ... f0 form the last 23 bits of the floating point number. The leading bit f23 (which is always 1) is dropped.

This is the first time I post a question on these forums My problem is as follows: I can't start gnome-terminal from the Applications->Accesories menu or from the Alt+F2 application launcher. I get a "Starting Terminal" in the task-bar that disappears after a few seconds and no terminal. I'm pretty sure there is something I did, but I can't really figure out what it is.
The things I've tried so far:
1. I used synaptic to remove and reinstall gnome-terminal. That didn't work
2. Started Xterm and tried to run "gnome-terminal". This is where it gets weird for me:
a. running the command as normal user I get a "Floating point exception" error and obviosly no terminal
b. when I do "sudo gnome-terminal" and enter the root password I get, as expected, a root terminal. I could live with that, but it's not ideal.
One of those odd things I learned the hard way is that if you are writing a shared object (library/.so) and any programs that will link to that library uses floating point numbers, the library must be compiled as if it uses floating point numbers. What that really means is, you need to declare at least one float in the source for the library or when the caller connects and tries to run code in the library, the process aborts.I end up putting a float pi (3.1415); in the code and getting an unused variable warning all the time. There has to be a simpler way, some flag to pass to g++ that says, "include floating point support even if you don't really need to."
p.s. Gosh I hope I remembered this correctly. I encountered this problem doing a multi-platform build for Windows and Linux. This COULD be a VC++ problem that I just carried into Linux by using the same source.
Just updated WinFF to version 1.3.2-1.1. Since then it won't start up any more due to a floating point exeption. System: OpenSUSE 11.4 (x86) + KDE 4.6.0 Debug info:

I had the same error with earlier versions of WinFF in earlier versions of OpenSUSE. Then I could fix it by changing the KDE window styles. The error also occurs with the WinFF qt-version.
I have been trying to convert a DVD9 to DVD5 using the following steps
1)Rip the DVD title(s) to harddisk with DVD:RIP in a project folder. This created VOB files of the the movie and the soundtrack you picked.
2)Concatenate (merge) the VOB files into one by running in a console: cat *.vob > movie.vob
3)demutliplex movie.vob and get the M2V and AC3 files out of there. tcextract -i movie.vob -t vob -x mpeg2 > movie.m2v
4)tcextract -i movie.vob -a 0 -x ac3 -t vob > movie.ac3
5)I then shrank the movie.m2v tcrequant -i movie.m2v -o shrinked.m2v -f 1.5

I have tried to learn how 64bit asm (nasm in my case) works and found, among the many disparate pieces of info on the net, a few vague inferences that floating point registers can be used for other purposes than what they are intended for, example: "64-bit Linux allows up to fourteen parameters to be transferred in registers (6 integer and 8 floating point)." This would be fantastic for string operations/manipulation (I have never used asm for floating-point operations), can anyone shed a bit of light?
View 8 Replies View RelatedI installed Fedora 12 in a virtual environment using VMware workstation, I am learning a Linux book. 1. The book ask me to change my directory to Fedora 12 DVD's RPM file directory under terminal. It assumes the mounting point for the disk image would be e.g. '/media/dvd/packages/', but if I type in 'cd /media/dvd/packages/' it obviously won't find the directory. So how do I navigate to the directory using CD command, but I guess put it more accurately I will need to find out what is the mounting point of the Fedora 12 DVD image in my VM.
2. I have another question with my root password, I cannot login as root when the VM first boot up, at the login screen where you are asked about your account name and password screen, So I have to use my normal user account (made up by my first name and last name) when I installed Fedora. But I know exactly what my root password is. The weird thing is I can still access to the root account in the desktops windows environment no problem. e.g. if I go to the top bar 'system-administration-authentication' program, it will let me in after I typed in my root password. In other words, I have access to all the admin tools in the desktop environment.
Is there any way to specify the mounting point of the windows partition(/dev/sda2 in this case) and make it mount on startup?
View 4 Replies View RelatedI have a very simple question I am creating a new partition for storing files, installers, documents, etc, I am going to make it ext4, now my question is, do I have to specify a mounting point?? I would not like to do that, but if I do not specify a mounting point, will I be able to access that partition? So in what cases you specify mounting point and when you do not specify mounting point?
View 6 Replies View RelatedI've been trying for a while mounting a EMC NAS share on linux. As far as I know the NAS share behaves just like a regular windows share, so the mount process should be very similar. On the NAS server, the disc "Disc1" is shared, and I need to mount a sub-subfolder of that share. This is my line in /etc/fstab:
Code:
//windows_box/Disc1$/folder1/subfolder /var/tmp/mount_test cifs defaults,acl,soft,uid=srvadm,gid=adm,umask=0027,file_mode=0600,dir_mode=0700,credentials=/root/cred.txt,sec=ntlmv2 0 0
When mounting the share, this is what happens:
Code:
[root@server1 tmp]# ll
total 8
drwxr-xr-x 2 root root 4096 Jun 18 10:39 mount_test
[code]....
In the console (i.e. bash), the "mount_test" word on the last line has a red background. When I issue "umount mount_test", everything is back to normal.
On Karmic, every once in a while this error pops up near the notification area at the top right (also see attachment):
Timezone Errors See Error Console: Unknown timezones are treated as the 'floating' local timezone.
But the 'date' command shows the correct date/time and timezone. /etc/timezone is also set correctly. The machine is running ntpd and is connected to the net 24/7 via ethernet. I also don't see any 'timezone' errors in /var/log/* Which software is complaining? What is the "Error Console" it is referring to?

I am having permissions errors every time I try to mount a windows host. I have a linux server and all the windows computers can see that computer and its files, but we wanted to start backing up the linux machine to one of our other computers. so I tried to mount one of the computers. here is the sequence of events:
Code:
$mount -t cifs //192.168.1.194/Admin$ /mnt/Anita-comp
password: (I have no password so I left it blank)
Mount error (13): Permission Denied
I tried all sorts of passwords we use around the office and none of them worked.
I then decided to try mounting one of our other computers. this one looked like it worked fine. no error messages at all. (I left password blank) so I look in my filesystem and the mounted drive is not in the /mnt/Anita-comp file. What gives?
i'm running slack 13.37. my machine has a "generic" wireless card which is currently sitting idle in it, since i used a wired interface for internet and local networking (i used the wireless interface for a while, but for what i need it wasn't a reliable or stable enough connection). my question is, can the idle card be used as a wireless access point on a separate subnet? if so how?
