int main()
{
return -1;
}
[youxi600@Arthas C++ Primer]$ gcc q1_2.cpp -o q1_2
[youxi600@Arthas C++ Primer]$ ./q1_2
[youxi600@Arthas C++ Primer]$ echo $?
255
[youxi600@Arthas C++ Primer]$
anyone can give me an advise? Many thanks!

I'm woring on a personal research project and would like to know if there are lilypond parsers for python available or I'll have to create my own.

View 1 Replies View RelatedI noticed that if I have "exit" in a bash script file., e.g. script.sh,that when the word "exit" is reached, and the script file being executed is not in the PATH nvironment, i.e. ". script.sh", the whole konsole shell profile is exited! What gives here? Is there another command compatible to "exit" to prevent this, or will I just have the leave the "." part in the PATH enviroment, which is, to my understanding, is not recommended? I desire for a "goto" function in bash script files

View 1 Replies View RelatedIt's been quite a run-around trying to get the Nvidia driver working.I have already followed a lot of instructions, at least onceI still get caught at "the pre-install script failed". When I looked at the script itself, it says it's "triggering an error status to prevent the installer from overwriting ubuntu's nvdia packages."Some say this script can be ignored, but it seems to be the only thing keeping my install from working.Some say install from root prompt, some say GUI OK. Some say d/l from NVIDIA, some from repository. I have been doing root, init 3, removing old drivers, etc..

using 'ntfs-config' to make ntfs partitions mount on bootup so that I can access my data partition from Ubuntu. The first time I installed ntfs-config it would not run. I uninstalled and reinstalled it and then it ran, but it didn't seem to be responding very well. I attempted to tick the partition I wanted and set it to be writeable. After I closed the app ALL my ntfs partitions were mounted, even the windows and system reserved partitions, and when I attempted to unmount them I got the following error:
Unable to unmount Data
Error unmounting: unmount exited with exit code 1:
helper failed with
unmount /dev/mapper/isw_dfjjdefcdi_RAID5p4 is not mounted (according to mtab)
I tried rebooting. I tried uninstalling ntfs-config, then reinstalling it (now it wont run again). So I'm at a loss as to what to do. I simply want my data partition mounted on boot up and writable, not the others.

How can I view and read /var/log/syslog if Ubuntu fails to be installed and therefore I cannot access this log?

View 3 Replies View RelatedAccidentally the usb plug on my WD "My Book" got halfway unplugged and I didn't notice it. when I rebooted it, it wouldn't read the drive. I tried using G Parted to repair it but no success, it just runs forever accessing the drive and never finishes. (I left it running an entire weekend and it didn't finish) the drive is formated ext3.
When I try to mount the drive in Ubuntu 9.10 it gives this error message:
Strangely if I boot into Windows and use the ext driver I can access the drive just fine. is this something I can fix? if needed I can use Windows to do any repairs.
