How To Run A Fortran Program In Command Prompt
Steps on how to run a file from MS-DOS or the Windows command. Use the dir command below at the MS-DOS prompt to list. Hello, I want to call a dos command in my fortran 90 code and I d'ont know how to do. Can somebody help me?
Next:, Previous:, Up: 9.100 EXECUTECOMMANDLINE — Execute a shell command Description: EXECUTECOMMANDLINE runs a shell command, synchronously or asynchronously. The COMMAND argument is passed to the shell and executed, using the C library’s system call. (The shell is sh on Unix systems, and cmd.exe on Windows.) If WAIT is present and has the value false, the execution of the command is asynchronous if the system supports it; otherwise, the command is executed synchronously.
The three last arguments allow the user to get status information. After synchronous execution, EXITSTAT contains the integer exit code of the command, as returned by system. CMDSTAT is set to zero if the command line was executed (whatever its exit status was). CMDMSG is assigned an error message if an error has occurred. Note that the system function need not be thread-safe. It is the responsibility of the user to ensure that system is not called concurrently. Standard: Fortran 2008 and later Class: Subroutine Syntax: CALL EXECUTECOMMANDLINE(COMMAND , WAIT, EXITSTAT, CMDSTAT, CMDMSG ) Arguments: COMMAND Shall be a default CHARACTER scalar.
WAIT (Optional) Shall be a default LOGICAL scalar. EXITSTAT (Optional) Shall be an INTEGER of the default kind. CMDSTAT (Optional) Shall be an INTEGER of the default kind.
CMDMSG (Optional) Shall be an CHARACTER scalar of the default kind. Program testexec integer:: i call executecommandline ('externalprog.exe', exitstat=i) print., 'Exit status of externalprog.exe was ', i call executecommandline ('reindexfiles.exe', wait=.false.) print., 'Now reindexing files in the background' end program testexec Note: Because this intrinsic is implemented in terms of the system function call, its behavior with respect to signaling is processor dependent. In particular, on POSIX-compliant systems, the SIGINT and SIGQUIT signals will be ignored, and the SIGCHLD will be blocked.
As such, if the parent process is terminated, the child process might not be terminated alongside.
Intel installers used to be more aggressive about modifying the Windows startup environment variables (the ones in control panel advanced system settings). As mecej4 said, this causes problems with use of alternate tools or modes, as well as with upgrades. Now that so many different combinations of Microsoft OS and VS versions have to be supported, the situation with setting up paths is barely under control with the compilervars.bat system. Combinations such as Inspector + ifort + visual studio on win8.1 seem to be impractical even with the flexibility which is available.
I don't have experience of XE 2014, but for XE 2012 and Ver 11.1 the setup can be a bit confusing. As mecej4 highlights, there are a number of uses of the environment settings which need to be considered when providing environment variable settings for a cmd.exe window. This can include: 1) compiling and linking using ifort and the various libraries ( which is provided by the 'Start All Programs Intel Parallel Studio XE 2013 Command Prompt Parallel Studio XE with Intel Compiler XE v14.0' approach. Compilervars.bat can also provide this, with the appropriate options for 32 vs 64.exe ) 2) running programs generated by ifort ( which is provided by the change to environment variables at install ) 3) running other programs or compilers which do not use ifort. ( this can require reversing some of the ifort settings, especially path= ) 4) running programs generated by ifort on computers where ifort or visual studio has not been installed. The use of compilervars.bat can be confusing, especially if both ifort 32 and ifort 64 are installed.
I would suggest that the environment settings for option 2 can conflict when option 3 is being used. Is it possible to consider a less aggressive change to environment variables for option 2) use and provide a clearer documentation of a way of enabling type 2) use? I have recently been performing option 4) on other computers to test out some ifort.exe performance on a range of hardware and have needed to check what environment variable changes are required. This has been a process of trial and error. Path settings are the most confusing to manage for this option, especially managing what additional directories must be provided.
How To Run A Fortran Program
Perhaps I have omitted to find and read the appropriate documentation, but a solution could be by having documented alternative batch files for options 1), 2) and 4) might help. I think the most confusing part of installing ifort is understanding the multiple places that ifort and VS files are located and which of these need to be replicated on other computers. Establishing the build environment has nothing to do with running programs. When you install the compiler, all the DLLs you need to run Fortran programs are put in PATH. (But not the performance libraries such as MKL.) What I do is copy one of the shortcuts in the Start menu to my desktop, edit it to change the 'Start in' folder, and just click on that when I want to start a new command session. Generally there are only two of these of interest, one for IA-32 and one for Intel 64. For running programs elsewhere, see.
Steve, Thanks for the link. This assists with option 4 I identified in Quote #10. Item 3 also requires some consideration, as the changes to the environment and path settings when ifort is installed can create some conflicts, although these occurrences may have been due to my mistakes.
I recently installed depends and found errors in the.dll's that were being used, as 32 bit and 64 bit versions were conflicting. This may have been that I did not have the correct environment provided, although I thought I could run a program (use option 2) using the default environment settings at install. I was also surprised at the different.dll's that were reported, as a number did not appear relevant to the.exe I had created.
