Programming :: Generating Files With Different Names At Each Loop In Fortran?

Nov 7, 2010

I am trying to write a loop to open four main-data-files. At each open of the main-data-file, I want the loop to open another four sub-files and split the data from the mail-data-file according to the creteria and dump into the four files. When the loop goes to the second main-data-file, it shall generate another 4 sub-files with different file name. And the process goes on. That means I will have total of 16 sub files for the four main-data-files. Each four files from the 16 files shall have specific name on it. Based on the code which I given below, I would say when the file at UNIT=100 is opened, 4 new files needed to be opened as well. They are:

Programming :: Can't Compile F77 Code Using Gfortran Or G77

Nov 17, 2009

I have legacy fortran 77 code that used to compile seamlessly using g77 on an old machine. I've tried to recompile it on a new machine (old one is dead) using the original makefile, but the linker fails under g77, while there are persisting syntax errors using gfortran. I have two source files readmixed.f and subroutines.f. Under g77 the object files are produced using


$ f77 -c readmixed.f -o readmixed.o
$ f77 -c subroutines.f -o subroutines.o

but the linking fails with


$ f77 readmixed.o subroutines.o -o readmixed
subroutines.o(.text+0x0): In function `norm1_':
: multiple definition of `norm1_'
readmixed.o(.text+0x3987): first defined here

Programming :: Generating Excel Charts From C?

Feb 24, 2011

how to generate excel charts from C, or if it's possible at all? For example, if I had 2 arrays that I wanted to export to excel and graph against each other. I know how to export it to a csv file, that's no problem, but I have no idea where to start with generating a graph of the data. I can't seem to find any examples anywhere. Just a simple example to show you what I mean: Code:

char arr1[] = {'a','b','c'};
int arr2[] = {10,20,30};
int main ()

Programming :: Code For Generating A Pop-Up Window In C

Aug 4, 2010

Unfortunatelly since i have no background at all about GUI programming, i dont know even the keyword for that i want to generate a pop up window from my program (written in C) which show a message and an OK button. in my opinion, maybe i should use directly the Xlib library and not the GTK or QT library for example so the program can work almost on every linux system. A code snippet/hint for the pop-up window then?

Programming :: Generating Timer Interrupts In C?

Jul 23, 2010

I'm trying to understand how interrupts work. Is there a way to generate timer interrupts in C. Also can we enter into the protected mode of the CPU. Does OS (specifically, linux) place any restrictions on user programs entering protected mode. If it does not, do we just have an assembly language program which changed the mode, followed by the C code... I'm just trying to understand how things work at the lowest level. So I'm trying to write few snippets to test my understanding.

Programming :: Generating Makefile Ans Configure Script ?

May 17, 2011

I know how to manually writing a makefile for my project, but I am new in using makefile & configure file generation tools like automake to generate a makefile and a configure script file.

I had done research on tutorials for generating makefile and configure script file.

I know that I need to manually write two files ( and

I use wxWidgets GUI library, libconfig library, and libpcap library to do my project.

wx-config is a tool that can return the library files and include directory for wxWidgets library.

When using g++ to compile my files, I need to add in this line "`/wxlib/bin/wx-config --version=2.9 --static=yes --unicode=yes --debug=yes --libs`"

How to add that line to the file?

Programming :: AMD CPU Generating Way More System Load Than Intel Xeon CPU?

Oct 11, 2010

I am running some muti-threaded code that uses a lot of memory (~6GB). I have it compiled on a cluster that uses Xeon 5160 quad core CPUs with 4MB cache/core, 8GB of RAM and kernel 2.6.18 (x86_64) and I have also the same code compiled on another cluster that uses Opteron 2214 quad core CPUs with 1MB cache/core, 8GB of RAM and kernel 2.6.28 (x86_64). On the Intel cluster the code generates barely any system load when I look on top but on the AMD cluster it can generate over 50% of system load. On the intel machines my process can generate a constant load of 3, while the load generated by the process on the AMD machines is about 1.6.

Does anybody know what could cause this? Could it be the version of the kernel or the difference between the CPUs (for example, the much smaller cache of the AMD CPUS)? My software and all its dependencies are the same on both clusters. I am also using the exact same version of GCC to compile everything.

Programming :: Bash: Generating A Random LETTERS Sequence?

May 12, 2011

I tried googling around but i cant find anything related to this: everyone seems just interested in random numbers, so when it comes to random letters there is a lack of informations. However, i am trying to figure out a wait to get a random letters string that matches a simple rule: it must be a sequence of consonant+vowel. So for example, these are some 6 letters strings i would like to obtain: wolupa, tafoke, zewevu, cupimo.

Programming :: Generating Keyboard Events In Shell Script

Nov 23, 2010

Is it possible to generate keyboard event "Ctrl+c" from a shell script code.? I have written a shell script to compile my application and copy it to the server home directory, inorder to run my application I need to start the server (by running a shell script). But before that I need to stop the the currently running instance of my server. To do that I have to generate a keyboard event (Ctrl+c which I press it manually). I want to automate the entire process by writing a shell script I am able to run the server just by adding ./ in my shell script. But before that to stop my server can I generate a keyboard by using a shell script event(ctrL+C) to stop server.?

Hardware :: Can't Get Movies (dvds Or Files) To Play Properly?

Feb 3, 2010

I just built a new Linux box & cannot get Movies (dvds or files) to play properly.

Xine playback is jittery but audio stays in sync with video.
Xine complains about "Too Many Dropped Frames"
Mplayer playback is ok but audio & video are way out of sync.
Mplayer says my system is "Too Slow"

I think it might be a RADEON driver issue because my Mandriva-2009.1 uses version: 1.6.1 & maybe those drivers ( don't fully support the ATI Radeon HD 4200 GPU. I know there is a prorietory driver (fglrx) but before trying it I'd like to here what you think. Here is some relevant info about my computer:

Asus M4A785T-M
CPU AMD Athlon II (X2) Soscket AM3
Chipset AMD 785G/SB710
Graphics ATI Radeon HD 4200 GPU (integrated)


Sorry this post is so long. I know it isn't easy to sift thru a long post because that is exactly what I've been doing this past week while try ing to get a solution.

Hardware :: How To Send Jpeg Files To Selphy Printers Directly?

Mar 2, 2010

most canon selphy printers does not work under linux, but i think its possible to send files to a selphy printer via bluetooth. and after recieving the file, it instantly prints the image. my question is, is there a way to send files from a pc to selphy via usb instead of bluetooth. i believe you can use obexftp to send files from pc->selphy and it will instantly print, the problem with this approach is that it takes a lot of time to send the file. if there is a way to use a cable to transfer the files then we could print directly. or is there a cable that somewhat simulates how bluetooth transfers.
