cannot run JackCompiler.bat

[Koen_Be3840]

All the software is running very well.

But I can't get JackCompiler running.

I'm following the steps in the book (p197) but no result.

If you are running Windows, create a file jc.cmd in C:\Windows that contains

@echo off
pushd .
call C:\nand2tetris\tools\JackCompiler.bat %cd%\%1
popd

Once you have done this, you can run the compiler by typing jc at the command prompt.

This assumes that Windows is installed in its normal location and that you installed Nand2Tetris to C:\Nand2Tetris. Change file paths as required for your system.

Someone else will have to help you if you are using a Mac.

That did it.

Thanks again Mark

Very useful

Hi,

I clicked the jack compiler in the tool to open it, but the graphic did not show up. I created jc.cmd as you instructed and put a command on the command prompt as below.

D:\nand2tetris\projects\09\Square>jc SquareGame.jack

However, it returned "Not recognized as a program or batch file that can operate internal or external commands." Then I set a path of jc.cmd on the control panel and still the command prompt returned the same error.

How could I figure this out?

Is this on a windows machine?

Try naming your batch file "jc.bat" instead of "jc.cmd" and be sure to add the directory that it is located in to the path. You also need to be sure that you are changing the path so that it persists from one instance of the command window to the next.

[Ichiro]

Yes, it is a Windows machine.

I renamed my batch file as "jc.cmd" and checked that I added the directory where the batch file is located, but it did not work. I am sorry but I could not understand what you meant by "You also need to be sure that you are changing the path so that it persists from one instance of the command window to the next."

I tried to open the batch file "jc.cmd" by typing "start jc.cmd" on the command prompt after setting the current directory but it returned, "file not found." The files on other folders such as "FibonacciElement.asm" in the D: drive was successfully opened in the same way. So does it have something to do with C: drive?

Don't call the batch file ".cmd". Use a ".bat" extension.

When you change the PATH environment variable, the default is that it changes just for the current instance of the Command Window. The next time you open a Command Window it will be using the original PATH. There is an option to change the PATH for future instance of the command window as well.

What is the contents of your batch file?

Where is the batch file located?

[Ichiro]

I finally figured it out. I noticed that I have set the wrong folder in the batch file. Thank you very much for making me check the content of the batch file.

After successfully compiling the jack files to .VM files, I struggled with running the Square program. I worked it out by reading the VM emulator tutorial, which is stored in the link below.
