system-console and tcl exec

--- Quote Start ---

What else could be missing or different?

--- Quote End ---

The shell where 'exec' gets invoked is probably different.

I'm not sure how to force the correct shell. I also had a similar issue in Modelsim, but never had time to look at it further.

It might be that you need wrap all 'exec' targets in a bash shell with# !/bin/bash at the beginning, to force the use of the correct shell.

However, as I commented, I have not looked into this problem ... but perhaps this comment will help you find the solution.

does qexec have the same problem?

--- Quote End ---

I'm not sure what you mean - qexec does not show up in the list of available tcl commands:

info commands *exec

only returns exec

in system-console, attemptingpackage require ::quartus::misc

to get qexec loaded doesn't work. I've never tried to use quartus packages in system-console, so I don't know if it's even possible or if a different syntax is required.

In the quartus tcl console, I get this trying to use qexec:qexec ls

error:while executing

error:"qexec ls"

::quartus::misc is shown as a loaded package

Neither exec bash ./myscript

nor exec sh ./myscript

gets a good response

myscript has a# !/bin/bash header

(In the working system-console, either syntax is successful)

According to this:

http://phaseit.net/claird/comp.lang.tcl/fmm.html#exec

Tcl exec does not use a shell.

This link has comments regarding trying to "exec dir". Perhaps they apply to your problem.

After some more experiments my conclusion is that exec works if system-console is hosted in a bash shell, and not if it's hosted by a native windows shell or windows process (such as Quartus).

Ok. That was what I was thinking too, however, the comments on the link I posted made me think otherwise.

So the question then becomes, how can you select the shell? I suspect the answer is that the shell is fundamental to the process, since when you launch the application, it inherits the shell. The solution might be to replace system-console with a bash script that starts system-console. That way when you execute system-console from a windows shell, you would actually be executing the script, which in turn executes bash, and then the real system-console application. With that setup, the shell should be bash.
