View 7 Replies View RelatedWhen I try to compile some Java code on Ubuntu 10.10 (kernel 2.6+) using make and a Makefile.
I get an error indicating that the make utility cannot execute the java compile command (javac).
The error reads: /bin/bash: line 6: .: /usr/local/jdk1.5.0_18/bin/javac: cannot execute binary file
I am executing make as root. I have enabled permissions on all directories in the path /usr/local/jdk1.5.0_18/bin/javac and on javac itself.
I get this error whether using a jdk installed via ubuntu apt-get, or whether I install the jdk myself. And I get it using either Java 1.5 or 1.6
My machine has an 80386 processor. I notice the make utility is built for i686-pc-linux-gnu
However, I can manually compile using javac.
I can compile calling javac from within a bash script.
I can compile using the java compiler gcj from the command line: gcj --main=HelloWorld HelloWorld.java -o HelloWorld.exe
But I cannot compile java code from the makefile. Any reasons why I might be getting this error?
I want to make a file called file roller for Ubuntu 9.10. The folder has a file called install.sh and some others that are make.
I figure first I need to make a file and then run install.sh to install. But I don't know how to do this.
I may not have noticed in other Fed releases, but in Fed 13 I am seeing a dot at the end of all file permissions. Example:
[pjs@linux ~]$ ls -ld Documents
drwxr-xr-x. 62 pjs pjs 4096 Jul 11 09:53 Documents
Even on files I create myself:
[pjs@linux ~]$ touch foo
[pjs@linux ~]$ ls -l foo
-rw-rw-r--. 1 pjs pjs 0 Jul 11 10:46 foo
It is the same throughout the fs. I have disabled as much of SELinux as I can. What does the dot mean?
I downloaded three iso-images, 1 dvd-image and 2 cd-images:
openSUSE-11.3-DVD-i586.iso
openSUSE-11.3-GNOME-LiveCD-i686.iso
openSUSE-11.3-KDE4-LiveCD-i686.iso
Being paranoid, I created iso-files from the burnt DVD-R and the two burnt CD-R to verify integrity.
The iso-file of the DVD-R was identical to the downloaded image. Both iso-files created from the CD-R were different in size.
The original size of openSUSE-11.3-KDE4-LiveCD-i686.iso is 719.323.136 Bytes.
I only got 718.938.112 Bytes when recreating an ISO-file from my CD-R.
The CD-R is from Sony. When the length of my ISO-file doesn't correspond to the downloaded one, the checksum file verification doesn't work.
error message when I ran my program that I couldn't open my local file. I have two files first one is called client, second one is called server I am using named pipes to sent a message from client to the other file called server in client I used mknod() to create the two named pipes,one for read,one for write and created new thread in client using fork() spawned a child process that executed the server file both named pipes are opened the client file got the message from the user and sent it through the named pipes to the server file when the server receives the message , it needs to verfify it is correct in the server file, a local file descriptor is created to read and send this verifing message when it is not correct but I am getting an OPEN() error when I tried to open this shared local array buff and attach it to a file descriptor where the message is kept why do I get this error in server file

That was really funny, I know that if i login the system normally i may login the system as 'tty7'. why i login as 'tty8' when logout one time? My edition is ubuntu 10.04.

View 6 Replies View RelatedHaving spent weeks perfecting my Ubuntu the way I like it, I was wondering if there is a way of preserving it as a either a liveCD or USB flash drive, with a view of using it on other PC's activated upon start up?
Possibly (under the USB option) with the option of launching from the flash drive itself, or installing onto a PC's hard drive.So, in essence, it would be a liveCD but custom made to reflect the way my Ubuntu looks and feels now? Is there any easy-to-use software available to perform such a task?

My problem is the following: When someone create a folder, the folder permissions are automatically set with:

Here is the deal: my school purchased a test prep which they distributed to us, the only problem is that it is for windows. When I try to run the exe in wine the program windows pops up but the screen is blank (i can see the menu bar and and the title bar). It appears that most of the information is located in a folder as html files (separated into chapters for each section) with links to all the figures/tables/questions
(also html files). This morning I have been trying to find a way to compile the html files into a format that I can read without having to hunt for each individual html file. I tried navigating with firefox but had to change each individual link before I could do that (very time consuming), I tried using doxygen (the GUI front end) to convert it to Latex/rtf/html/xml (all the formats) but did not have any success (It could be that I am using the app wrong). I tried opening some java applications found within the application data folder in hopes that it would bring up the navigator without success. And even tried installing java in wine (unsuccessfully) to see if that was the missing key to run the program in wine.
My question is, do I just have to fork out the $500+ that it would cost me to purchase the books instead of using the school provided program (free to us)? or is there a relatively simple way to compile these files into a format that could be readable.
tl;dr - have multiple html files for a windows native program that won't run on wine that I would like to convert to a more easily readable format (i.e. chm, pdf, etc), is it possible?the program was legally acquired through my school, I did not download or pirate it. I am not looking to distribute it, just looking to use it for my own studying purposes without spending $500+ or buying a windows license/computer.
