![]() ![]() ![]() In LabVIEW you can use the System Exec.vi to execute a system-level command line that can include any parameters supported by the application you want to launch. To call the interpreter that will execute the script use the following command(s):įor Perl scripts, use: ' perl argument' as shown in the image below.įor Python scripts, use: 'p ython scriptName.py argument' as shown in the image below.Ĭalling Perl and Python Scripts from LabVIEW.Navigate to the directory where the Perl or Python script is saved.Both Installers have built in functionality to edit the Environmental Path Variable to include the directory location of the interpreter and corresponding library files.Ĭalling Perl and Python Scripts From the Command Line Note: This example was prepared using the Using the ActivePerl 5.10.0 Interpreter and the ActivePython 2.6.1 Interpreter, which can be downloaded from the External Link: APSN ActivePerl Website and External Link: ActiveState ActivePython Website, respectively. Add the directory for where your Interpreter is saved.In System Variables, select the Path variable, and then click Edit.Right-click on My Computer and select Properties.You will need to ensure that the Environmental Path Variable is modified to include the directory in which the Interpreter and corresponding library files are located in order for the machine to recognize the Perl and Python tokens as commands to use the interpreter. You can edit the Environment Path using the System Properties Editor. If you do not have the required privileges you should contact your Administrator.Calling the interpreter can be simplified by changing the Environment Path Variable to include the location where your interpreter and corresponding library files are saved. In order to perform all of the above steps, you will need to have Administrative privileges on the target machine. Once the installation has completed successfully, the above actions may be undone although restoring the environment variables or the registry values may interfere with the proper operation of your new ActivePerl installation. This can be accomplished from the command prompt using the following command: Realizing that this is not always possible, you can follow these steps to ensure the other installations will not interfere. The sure-fire solution is to make absolutely certain that no other installations of Perl are on the target machine. We have determined that some of these problems are due to other installations of Perl that may be pointed at by something in the environment. The first thing to note is that you CANNOT install ActivePerl 5.16 over an older version of ActivePerl based on 5.14, 5.12, 5.10, 5.8, 5.6 or 5.005, such as build 1204 or any other 1200, 1000, 800, 600 or 500 series build. It seems that some people are having problems with the ActivePerl MSI installer.This caveat currently applies to extensions such as Tk and Storable. In particular, fork() emulation will not work correctly with extensions that are either not thread-safe, or maintain internal state that cannot be cloned in the pseudo-child process. The fork() emulation has known limitations.If you find the trick before me, please post it. The only release note provided is below, which I found inadequate. Here’s are the edits required program on lines 189 and 194: You need to change line 57 from port 5050 to port 3306, and “ SharedSecret” to “ s3krit“, as shown: GRANT ALL ON test.* TO also took the time to update the MySQL to Perl 5.16 unfortunately, at the end of the day I didn’t get it working. * TO 'localhost' ĬREATE USER USER IDENTIFIED BY 's3krit' CREATE USER 'localhost' CREATE USER 'localhost' IDENTIFIED BY 's3krit' GRANT ALL ON test. ![]()
