I am not sure if this topic is in the write forum or notbut I shall tell u my idea firstI want to make a RouterOS like mikrotik : http://www.mikrotik.com/ i know mikrotik is notfreeand I want to make my program free (GNU license) and is easy to use and with good GUI but me alone will be impossible I don't know where to begin from and what languages should i program in I know a lot of programming languages and i did a lot of projects with themI know C/C++,java,assembly scripting languages : perl,TCl/TK,lisp,shellI want it to be a project like the kernel or any popular software I want some directions so i can start and i wish to have also some programmers
i have a xeon machine with ubuntu os machine specification is 3gb RAM 3 scsi hard drives each 73gb it have two ethernet cards one ethernet card is connected with adsl modem and the second is connected with LAN. now what is mikrotik doing for me is control access to bind mac adress with ip adress and control the band width for induvisual conection.
I want to gave much details as possible. working directory (~/a1/shell) in the shell directory i have Makefile. also in the shell directory i have subdirectory's (obj, src, include)
My current Makefile
Quote:
#What needs to be built to make all files and dependencies
clean:
# End of Makefile
I wanted it so: all .o files are created in the obj subdirectory, and my application, sshell, is created in the shell directory.
I am getting this error when i run the make run: No rule to make target 'shell.h', needed by 'shutil.o'. stop
I've made a C++ program and compiled it and I can run it in the terminal but I would like it to run like a normal application in the application menu or on the desktop but I don't know how. How do I make it run like a program in the application menu?
I'm trying to make one that has some sorts in it for now. I know you have to make a header file and a .cpp file. I'm using VC++(yes, I'm in school so windows in needed. I use Ubuntu at home I swear D if it makes a difference. What goes in the header file, how is the cpp file set up, and then where do I put the files once I'm done?
I am compiling some c++ code trying to connect it with libi2cbrdg.a library where I have a lot of functions. So when I am doing this gcc -g rand.c -lasound -li2cbrdg -o rand.I don't have missed functions instead I have some other C/C++ connected errors, when I am using g++ compiler like this g++ -g rand.c -lasound -li2cbrdg -o rand.it does not see functions inside that library but everything fine with c++ code.How can I make g++ behave like gcc in this case?
(i) I usually make multiple dir using -p optionex: mkdir -p dicttest/audrep/tdriver/testNow after creating this dir's i stay in current dir instead i want to go directly to test dir how can i acheive this.(ii) When i execute which command as followswhich testerm i will get the location of testterm now i want to open this filewhen i did in this wayhich testterm | vi The file dosent get opened how can i acheive this ?ex:
linuxx86:110$ which testterm /view/rdl110_linuxx86/vobs_usrrdl/sc/testterm linuxx86:110$ which testterm| vi
I was thinking about how to make a dynamic array in C, and I thought that it would be much better if it could accept any data type. Is this possible? Of course I thought about void pointers, but how do I store the actual data?
I use an application called redbutton-browser to access some of the things available on the redbutton digital tv channels. It compiles fine if I use a simple make but fails if I try to run parallel jobs with make -j4. I'd like some help altering the Makefile so that it does a few commands sequentially before it does the rest of the Makefile in parallel.
I'm developing a new command to be executed on the grub shell. However for some reason the .c file I added doesn't get compiled. How do I notify make of this new file?When you type in the make command, a load of gcc commands come up, where do these come from?
I know this because I typed in random letters but the compiler continued on. However tried it on an existing file it came up with a compile time error.
I have written a small script from that iam appending the output to a file.If multiple users invoke the same script or if i invoke the same script n number of times (using &), the output file(ZZ/OUT) contains messup information.
I have a process and two threads running in it. Thread1 is my GUI-Thread (using FLTK) and Thread2 is running at the first 10 sec. after start.Now, I would like to make Thread2 "nicer" to Thread1, because otherwise GUI stucks sometimes. But I didn't find a solution.Is it possible to define the "niceness" of threads inside a process (to each other)? And if so, how do I have to do this?
make the move away from programming with windows. I have just downloaded the souce code to the Fluid FLTK GUI designer version 1.3.0. and i am completely lost. It just a huge pile of folders to me i don't know where to start how do I compile it ect....? Can anyone with experience maybe give me some pointers on how the most productive way to go about reading open source metarial is? like are there any files with classic names i should be looking for in particular?
is there a way to make the /proc filesystem writeable? With aufs or unionfs i can't join the /proc filesystem with a writable directory directly. But i think it should work by using one of this file systems.If i try to join two dirs write-proc and virtual-proc Code: mount -v -t aufs -o dirs=/tmp/write-proc/:/tmp/virtual-proc/ none /tmp/joined-proc/ and afterwards make a bind mount /proc to virtual-proc Code: mount --bind /proc /tmp/virtual-proc/ i can't see any change in /tmp/joined-proc.
I have a timer thread, and when it expires, it sets a flag. The only problem is, if any higher priority thread comes in between, then the timer is not expired in real time.Thus i want to set a highest priority to my thread. Now, i know 2 algos, which can make my thread in real time are: SCHED_FIFO and SCHED_RR.
So, here are my queries: 1) Which scheduling algo is best suited for this purpose? 2) Is it guaranted to work in real time if i use that algo (you suggest in 1) and set the max_priority by getting the maximum settable priority for that particular algorithm using, int sched_get_priority_max(int policy);
i've been using a awk script to calculate my data... i have 3 files:
file a1.txt:
2 3 4
[code]....
the results were (3.5, 6 and 3) which is pretty easy.. now i want to combine all this into 1 file and each have different columns and called it avg.txt which have something like this in the end:
I am starting a project of my own (and learning C++ at the same time. I got my program to successfully scan a custom netmask, but it is REALLY slow. I want my program to do something similar to nmap -sP xxx.xxx.xxx.xxx-xxx. How to speed it up? Such as pinging more than one IP at a time...
I am trying to compile systemc. Configuration is done OK and Makefiles are created. As soon as the "make" command i issue, recursively reaches the "utils" directory, errors are produced -declaration and include errors.
The files referenced by the errors DO exist and i hava managed to give g++ "-I ${LD_INCLUDE_PATH}, ie the variable, where all header dirs are listed. Libraries and compilers for gcc3.3 and g++3.3, i believe, are installed OK. code...
I am working with a third party that use windows to compile. When we port that code I am running into a lot of case issues where the includes are not case sensitive. Is there any option in GCC to make it case insensitive. I know its a long shot, as I have done reading and does not seem so.
Most of FLOSS projects has a lot of code to compile, and a big make process. On my new PC i need a half hour to compile Inkscape, and on my old laptop i need something near to 2 hours. There is a way to put a percentage of the work done in the makefile? (Always there are a hard and dirty way... there is a good, beauty, common way?)
I have been working on a project for a while now that involves a rather complex daemon that has to be simultaneously running different tasks. For example one of these tasks is to receive IP packets from the Netfilter queue and place those packets into one of several internal queues. While other tasks involve taking IP packets from those internal queues and processing/manipulating them and finally returning them back to the Linux network stack.
As I as I have no previous C experience before starting this project I just spawned a new thread each time I needed the daemon to be doing something else while those other tasks continued to run. Is there any other way of doing this or is this pretty much the only way of doing this? Because C is procedural I could not figure out any other way of doing accomplishing what I wanted. Should I have done it some other way or is this the correct and only way I could have gotten my C app to be running multiple tasks at the same time?
Any pointers to make a shell script in cronjob or using at to be user interactive. We have a requirement to script a program where it prompts the users in CUI for feedback and capture the output in a text file and act based on the feedback.For eg: At pre-defined time i should prompt the acitve users whether it is ok to shutdown, whose feedback would be captured in a text file. Post which act on the updates in the text file
I am trying to make a hash of objects in perl (long story.) I have a package containing the main hash and all the subroutines necessary to work with it. My "new" subroutine used to add an object to the hash goes like this:
Using PyQt4, is it possible to make a program where you can separately write custom QWidget subclasses and let the user add/remove them to your main app?
I've given the output from `df` on AWK's stdin. But what I wonder is if there's a way to get AWK to run `df` itself, produce the same output, and exit? Doesn't seem to be that simple. Here's some examples: Works for some reason, and I think only in Bash (nothing is required in the $()
[code]...
does AWK absolutely need *something* on stdin, before it begins to process the data? Can it be made to open a file or stream internally, act upon that as though it were the stdin, and exit?
