I am in the process of learning bash programming,i have a any problem,about call my own C language functions directly or runtime from bash shell?
example :
each functionCalltobash1 and functionCalltobash2 have many other function inside themself.
Is bash shell support invoked my C function?

All the variables have been declared before and there is no problem with that. The problem (error message) is in the (first) line that deals with open(unit=3,file='..//').
I am trying to install the Matlab 7.5 compiled runtime for 64-bit Linux (MCRInstaller.75.glnxa64.bin) and keep getting a "No Java Runtime Environment(JRE) was found on this system." error message.
I understand the JRE is bundled with MCRInstaller and will self-compile/install. However, I don't have admin access, could this be the source of the problem? If so, how could I fix it (not sure how to direct it to install locally without going into the source code)?
I got around this error before, but stupid me didn't write down what I did and I forgot.
I know there is a way to call winapi in runtime in windows. I want to ask how can I call a system call in gcc in runtime (when I don't know what it can be)? I don't mean syscall that I think is for calling only system calls and not library functions.
View 4 Replies View RelatedI'm writing an application with a plugin architecture and would like modify (specifically add to) the dynamic library search path while the main executable is running.
The plugin paths are not known until the application is running so I can't set LD_LIBRARY_PATH ahead of time.
My understanding (although I haven't tested it) is that the executable will only parse the LD_LIBRARY_PATH once, early on, so modifying this environment variable at runtime will have no effect.
(Note - on Windows the solution is to modify the PATH environment variable)
I know it's possible to specify the full path to load a dynamic library, and this would work if the plugin(s) only had a single library to load, but some of them will have a bunch of libraries with their own inter-dependencies, so I'd like the plugin folder(s) to get added to the search path to pick up the dependant libs.
how can I trace the method calls in Java during runtime?

I'm new to the linux world and its been quit sometime since i've done any programming. However, I'm writing a program which simply calculates the load average of a process. In doing this I need to use the uptime command for linux in a java program. I've done a little bit of searching on the net and it mentions this is possiable by using java runtime command. Unfortunatly though I have yet to find a working example of this. I've tried just simply reading the /proc/uptime file but I have no clue how to format the 2 numbers in seconds to make it the same as if you just typed in uptime in the linux command prompt.
View 2 Replies View RelatedAfter installing Fedora 14 and being satisfied with the behaviour and the packages installed for it, i want to replicate the same installation in a few more PCs, so i installed Revisor to make with it an iso file that reflects my actual installation.
The problem is that if i run the software from Applications->System tools->Revisor, nothing happens after giving the user password.
Then i run it from a consele and this error is produced after giving my password: "Cannot find anaconda-runtime in /usr/lib/anaconda-runtime"
But anaconda is the environment used for installation, so it is installed from the very begining. Why this happens?
I would like to know how do I print the line # in a script. My requirement is, I have a script which is about ~5000 lines long. If there are any errors happen I just exit. And I would like to add the line # of the script where the error happened.

#!/bin/bash
trap "echo 'you got me'" SIGINT SIGTERM # to trap ctrl+c
echo "Press ctrl+c during 5 sec loop"
for ((i=0;i<5;i++)); do

How come code behaves normally and stops when ctrl+c signal is caught and resumes, but after I use at least one timeout read in the code it looks like, if signal is caught again it doesn't pause the execution but skips the loop. If you remove -t (timeout) option from the read, both loops look the same!

I have written quite a few separate bash & scripts and php scripts that up to now I have run from cron jobs. However I have to estimate how long each takes to run, before running the next and so it probably takes much longer than necessary to run them all. They have to run in order.
Now there are so many I am thinking it would be better to have a master bash script that would run one after the other, but I am not sure how to get the master script to wait before starting to run the next script. Is this possible and is there a command that will make the script wait between bash and php scripts , for them to finish, before running the next?
I would like to get the filename (without extension) and the extension separately. The best solution I found so far is:
Let FILE="thefilenameofsomefilesfor_instance.txt"
Code:
NAME=`echo "$FILE" | cut -d'.' -f1`
EXTENSION=`echo "$FILE" | cut -d'.' -f2`
I think it would be better to count the len and remove 3 chars to right to get the extension, but it can be macintosh filenames with have 4 chars for extensions.
I've never programed shell scripting.
Code goes like so:
I simply want to read a file "data.txt" line by line Then char by char and add them into a result var. The file is supossed to always contain numeric values
I need a code for a multi client and server

The first is Mp3 which is no problem for Ubuntu. The second is WMP, also no problem. The third format is WMA, which uses an Overdrive Media Console designed to run in Windows. This has stumped me. I was hoping to run it in Wine, but the media console refuses to download into Ubuntu. Then I tried downloading the audio file straight into Ubuntu. What I get is a text file in some programing language, parts of which are in readable english describing the book and lines of code refering actual audio files(HTML tags?).So Can anybody tell me how to play WMA audio books in Ubuntu. The rest of the media is installed and works perfectly.

i'm in the process of learing C++. currently i'm creating shell scripts to get things done. i'm just curious how, as a programmer using C++ you would get a similar job done.as an example i have a script that takes the contents of files, pipes it to some sed and awk commands, which is piped to create a new file. that file is then imported into a mysql database.if you were going to do this in C++, would you call the sed/awk programs to modify the file, or can it be done within the program itself? i'm probably jumping the gun here because i've just started learing about pointers so this is above my ability
