Programming :: New MPICH2 Installation - Interfering - With -make - Cant Compile Fortran Programs
Jul 28, 2011
Actually I had a folder called Lib, in which I had a few libraries installed and configured.(MPI, PETSc, SLEPc) I accidently deleted (by rm) the contents of that folder.
Then I reinstalled MPI,PETSC,SLEPC using the same tarballs as earlier(thus, the version etc. is the same).
I already had a fortran program with many modules and subroutine files, and the corresponding makefile which used to compile and run fine. But now when I type "make" in the same directory as before, I get this: (shortened, many similar errors)
Code:
Firstly, why is mpif90 compiling my program when I didnt tell it to? In my makefile, I have specified gfortran as my compiler....nowhere have I even mentioned mpif90. Such a thing never used to occur before.
Also, if I rename file_variable.f to file_variable.f90, these errors dissappear (I understand why, but that is not the problem), but a new error comes:
Why is the new MPI installation interfering with make ? I want to go back to how things were before I stupidly broke all installations. The errors themselves are not the problem, the problem is why the new mpi installation is interfering with make.
It seems as if mpif90 has taken over make and gfortran. I suppose I didnt install it correctly, or probably I didnt uninstall the earlier one correctly.
Everything that worked earlier doesnt work suddenly. I use ubuntu 11.04 MPICH2-1.3.2

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 work on Fedora 9 and I'm unable to compile my c++ program using the make in the terminal as well as in the IDE-Anjuta.although 'make' works fine with C programs,I get an error that g++ command is not found whenever I try it with C++ programs.

I was wondering about a package that can be used to write and compile/run programs in different programming languages. I was also wondering how possible it is to program in Visual Basic 2010 in openSUSE if at all.

I have Slackware 13-64 bit and I would like to cross-compile some Fortran and C programs to windows 32 and 64 bit applications. The Linux versions utilize X11 for the graphical users interface. I have tried MINWG but I could not get it to work, either in pre-built binary or source code form. Is there a binary version that works on Slackware 13? Alternatively, is there another method available?

i'm currently using the gnu compiler "gfortran" , but i don't think the executable files it creates are compatible with windows XP (though i may be mistaken). my boss needs a few simple programs that i have written, but i will not be able to compile the code on his pc. are there any compilers out there that i can use to create such executables?

I have a fortran program example call like this:
This call cant run my fortran program because they output to the screen that the file ' ' (empty) cant be loaded!
So the problem is that my program cant see the file in the long path name above ( the real name is a bit more longer). I try with shorts path names , and the program can run, reading the input file.
I googleit for this type of error and only found that bash have limits on the filenames and inputs, so i change them (/usr/local/linux/limits.h or some like) to a very high value (999) ,but no success.

Where do I find the linux-source package and the linux-headers package? Are they on the CD that I can copy to /usr/src (is that the right place...)? Or do I need to download them from the old-releases.ubuntu.com site?
The issue now is that the nVidia installer from their website wants the source code to build the right packages for this machine, however, I do not have the src directory with the source code that it is looking for. Is there some way to give this too it now?
I am running Mythbuntu 7.10

I've installed openMPI-1.4.1 on my laptop and I'm trying to compile some fortran code I've written using MPI. I downloaded the openMPI-1.4.1 file from the openMPI website and used the shell script they provide to install it. This is the shell script:
shell$ cd openmpi-1.4.1
shell$ ./configure --prefix=/usr/local
shell$ make all install
There was an additional line extracting the tar file, but I did this by hand. The first time I ran this script there was an error on the final stage saying that a directory couldn't be created because of lack of permission. I decided to run the script again this time as a sudo.
Having run the script again everything appeared to install properly, however when I went to compile some fairly simple code I got a message saying that the compiler couldn't find MPI. I was using this command: gfortran messages.f90 -o messages I looked on the openMPI website where it recommends compiling with a compiler called mpif. However when I type mpif messages.f90 -o messages I get an error message saying mpif isn't a recognized command......

Would like to make an installation with a number of programs. I would like to take a snapshot ( backup ) of my installation and being able to restore that later.
How can I take a snapshot, is it possible to 'save' everything to an ISO and burn
to a CD ?
I am using version 10.10.

I have XAMPP installed on my server and would like to keep it there. However I'm pretty useless at terminal so would also like to have a control panel. Can I install LAMP over XAMPP without it interfering with my current apps? I'd like to use Easy Hosting Control Panel ( ehcp.net ) or something similar to help me manage FTP users and Mail setup but I really don't want to interfere with my current XAMPP.

I'm trying to call some Fortran 95 code in C, but I'm having problems with integers not having the same value in C as in Fortran, and changing values upon each run of the program. I think it has to do with the integer type, but I don't know how to fix it. I'm running Gentoo x86. Here are the files I've got:
foo.c:
Code:
#include <stdio.h>
extern int qux_();
main() {

There are examples everywhere about calling f77 subroutine from IDL, but I have not found any material about IDL calling fortran written in f90 way(free style). I tried the following example, but write the subroutines in free style. When I run the makefile, it gives an error 'undefined reference to main_'.
Code:
SUBROUTINE SUM_ARRAY(argc, argv) !Called by IDL
INTEGER*4 argc, argv(*) !Argc and Argv are integers
j = LOC(argc) !Obtains the number of arguments (argc)

I want to call a subroutine in Fortran 90 from a c++ code. I can do it, when the fortran code have no module. But i need to call the subroutine in a fortran code that have an module. I have a simple program that shows my problem. The Fortran code is:
Code: !add2.f90
Module add2
Implicit none
Contains
[code]....
collect2: ld returned 1 exit status I Dont know where is the problem. Maybe it is in the call of the function. I found that the syntax have this form: extern void __namemodule__NMOD_namesubrutine(arg)

I have two arrays of data, called data1.dat and data2.dat. each contains 60 data. What I want to do is to compare the data in each file and write the counting into bins. It goes like this. First, take the first data in data1.dat file and compare with the 60 data in data2.dat file. If there is any data which is same with the data in data1.dat then it count in bin. The total bins are also 60. Next it goes to the second data in data1.dat and compare with all the 60 data in data2.dat. If there is any data same then it add in second bin. And it repeats to all the data in data1.dat

I'm not a Fortran coder but I need to call the sub-routine ADAPT.f from a c code.This subroutine calculates a multiple integral of a given function.My problem is that the c code works with no problem in a 32 bit machine but it does not in a 64 bit machine, and the problem seems to be related to adapt, which calculations gives a NA rather than the result of integration.Since fortran is quite obscure for me, I don't know why is this happening. Maybe I should change some data type (from real to double), but I'm not sure. Does anyone have a clue?

I have a program which reads some parameters in from an input file before solving a differential equation. This program compiles fine, I'm using Numerical Algorithms Group (NAG) libraries to solve the differential equation so I'm also the NAG compiler called nagfor.
The namelist I have is declared as follows:
And the input file is:
When I run the code I get the following error message:
I really can't see what's wrong with this code.
Also, I'm using Fedora 11, and running the code in tcsh if this is relevant.

I've tried compiling C++ programs with extension .cc and .cpp. I've tried compiling with gcc, g++ and even cc (with .cc extension files). Earlier (as g++ wasn't installed) i tried installing g++ (sudo apt-get install g++) for which i got the message "g++ has no installation candidate". Later from Synaptic i found it as g++-2.95 and installed it. I've also installed pentium-builder
Whenever i've tried to install "build-essential" (using apt-get and aptitude) i've got messages along the line of "no installation candidate". I've searched many posts and not got the answer for this. I've treid update and upgrade before installation, no use. I have all the repositories checked in software sources and the server as "main server". Now, the main problem is: (when trying to compile a .cpp file)
user@dell-desktop:~$ g++ hello.cpp
Unable to exec g++.real: No such file or directory
ser@dell-desktop:~$ gcc hello.cpp

I am dealing with one FORTRAN 90 code, have made small changes.
milenko@milenkons:~/mt4$ make mt4
make: 'mt4' is up to date.
milenko@milenkons:~/mt4$ ifort -c MT2DDIB1.FOR
milenko@milenkons:~/mt4$ make mt4
make: 'mt4' is up to date.
milenko@milenkons:~/mt4$ make mt4
make: 'mt4' is up to date.
milenko@milenkons:~/mt4$ make mt4
make: 'mt4' is up to date.
I go for make command but it does not see that the source code has been modified.Than I do compilation from command line,try make again but no use.
F95=ifort
FFLAFGS= -O1
mt3: driver_mt2ddi.o constants.o settings.o params.o mt2dmod.o fdsystem.o mt2ddat.o mt2dsens.o
$(F95) -o $(FFLAGS) mt3 constants.o settings.o params.o mt2dmod.o fdsystem.o mt2ddat.o mt2dsens.o driver_mt2ddi.o

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:
maximum_dist_001_064.dat
maximum_dist_065_128.dat
maximum_dist_129_192.dat
maximum_dist_193_256.dat

i am graduate student and my X colleague gave me this Fortran 77 program to run my result files with. She is no longer reachable. I compiled the following program with gfortran, it compiled well but, when i run it, gave me end of file error. My output file (which is the input file for this program (DFILE1) ) has about 78,000 lines of velocities of atoms (Vx, Vy, Vz with 1000 steps.. an example of some of the atom's velocities in the 1st step is given at the end of this program). I will be highly obliged if any one can help me with this.I run this program on opensuse linux 11.3 version /32 bit/i586
error message:

I (my friend) have a fortran program with the code along the following lines:
Code:
SUBROUTINE NY
REAL, DIMENSION(4000,4000) :: a, b, c
...
RETURN
END SUBROUTINE PARAMETERS
The problem is that the huge matrices are retained in memory even after the subroutine ends. Is there an easy way to declare the arrays in a sort of dynamic way, like they were in the following C example?
Code:
void ny(void) {
double a[4000,4000];
...
}
I mean in the C example the memory is released as soon ny() exits.
