Ubuntu :: Compile Parallel C Program With MPI Codes?
Jun 20, 2011
I have a simple testing program like this:
/*The Parallel Hello World Program*/
#include <stdio.h>
#include <mpi.h>
[code]...
My program is, I can't compile this program using gcc, and I can't find something like pgcc in ubuntu. How should I compile this program? After compiling, what should I do to run this program? Can I use something like mpirun to run it? I want to try to use both cores of my computer to run it and make it shows Node 1 also besides Node0.
I am a student taking part in a comptition. We have a set of questions to complete within today. Can anyone please help me out with it. I have a custom written "echo" program in C, running on port number "1220" which echoes back the first 16 characters of whatever is given as the first command line argument. But somehow, my brother had got unauthorized remote root access. The program is given below. How did he do it? Please give the exploit code and explain how it works.
I am trying to write to the parallel port pins from a Perl program running Ubuntu Linux, to light up led's on a bread board. I've already accomplished this on this same box using a C program, but I cannot get my code below to work. I believe the problem is with the line: $parport = Device::ParallelPort->new('auto:0'); I've tried different variables between the ('') ticks, but nothing has worked. I use Perl on my web pages for forms, but this has stumped me.
Code is below: #!/usr/bin/perl require "subparseform.lib"; &Parse_Form; print "Set-cookie: cart_id=1234; user_id=123; "; print "Content-type: text/html "; use strict; use CGI; use Device::ParallelPort; # use Device::ParallelPort::drv; # use Device::ParallelPort::drv::linux # use Device::ParallelPort::drv::parport # Set up your parallel port object and tell it what driver to use. #my $parport = Device::ParallelPort->new('auto:0'); print "It works!!!";
I'm new to linux, and I've been following a paper [URL] to build a linux cluster using RedHat 5. I'm up to part VII step 5, installing the message-passing software MPICH2-1.4, and I'm not quite sure how to "execute the compile command 'make' to generate the binary codes of MPI."
I need to make some C program under linux to make some scripts that can talk to my Server's Parallel port by sending some quare signal as high or low, so what i can do ?
I am trying to compile a very simple 32-bit program on my 64-bit fedora 12 install, but it won't let me.
I get this error.
I tested it on the school server (64 bit Red Hat Server), and it compiled flawlessly without any warnings. I think I am missing some libraries, but don't know which.
I was using my college's unix server (ubuntu presumably) to compile programs in the laboratory. Now, i have installed Opensuse 11.4 with gnome3. I have installed the Developers pattern, and almost all the packages that looked relevant (which came up when i searched for libgc , gcc, and all). Now, i cant compile a program:
Code: /*program to test file I/O and getch/putch functionaliny in gcc*/ #include<stdio.h> int main() { FILE *fi; char ch;
My Fedora 14 have installed gcc-4.5.1-4.fc14.x86_64,qt-4.7.1-5.fc14.x86_64, I don't know how to use g++ to compile QT program. Do I need to set PATH or something else?
from the commend line i went to compile the c program by giving the commend "gcc first.c -o first" but the commend line showing gcc is not found. iam using fedora 13 what can i do to compile the program . the program i used to compile is below
#include<stdio.h> main() { printf("hello word "); }
i am not able to compile my test program which uses gtkmozembed.As i am very new to this, i dont know which are the packages to be installed and how to compile
I want to cross compile gtk program from linux to arm. I am using ubuntu10.04. How can I cross compile it for arm. I have tried this but this is my output: root@habesh-laptop:~/habesh/gtk# /root/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-gcc -o trail1 base1.c 'pkg-config --cflags --libs gtk+-2.0' cc1: warning: include location "/usr/include/gtk-2.0" is unsafe for cross-compilation cc1: warning: include location "/usr/include/atk-1.0" is unsafe for cross-compilation cc1: warning: include location "/usr/include/cairo" is unsafe for cross-compilation .....
I am new to Linux, and I just tried to compile a program (powertab tools) from source. I'm having som problems doing that. The "./configure" command works fine, but when I run "make", it gives an error:
Code: seppe@Thuis:~$ cd ptabtools-0.5.0 seppe@Thuis:~/ptabtools-0.5.0$ ./configure checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no
since last days I am trying to run a simple c / cpp program using eclipse in my newly installed fedora 13, but every time it says either "program file not specified" or "binary error"
I have used a new header file named curses.h in my program.when i try to compile my program it shows me the following error "No such path or directory".What may be the problem?A part of the program is shown below
I do not even know where to begin, and what logs / errors show: I am completely confused in the variables, etc.I can not install PAL Like all successful, and the program to compile, but I can not verify this.I tried premake and one Engine ODE - then I get an error segmentation, when you start paldemo.If I use cmake, then get this:
I would like to modify my init.gz and add udp-sender to this image. After copying the program compiled on my system to init image I have error when I try run udp-sender: udp-sender not found When I checked ldd I saw that the some libraries are missing. I copied them from my system but still got the same error. how can I compile program for my init.gz?
i just grabed a book and wrote a program and tried to compile it using 'javac' and everytime i'm getting this error:
javac Example.java /usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../lib64/crt1.o: In function `_start': /usr/src/packages/BUILD/glibc-2.9/csu/../sysdeps/x86_64/elf/start.S:109: undefined reference to `main'
I want to compile a program with the source I already have but I have to add an option. When I run the command ./autogen.sh the terminal returns aclocal not found. Is it a package or something i have to install?
