Re: [Discuss-gnuradio] FW: Re: File sink permission error on Windows

When I use GRC 3.7.9.2 ,  'C:\Work\GRC_Work\good.bin' works and 'C:\Work\GRC_Work\bad.bin' fail.

But after I install GRC 3.7.11.1, both works well.

Kim,

 

Ok, I'm feeling somewhat confident that this is a unicode or slash issue.  The character you said is your path separator appears in my email client as a W with a horizontal line through it, but when I cut/pasted that character, it became a back slash.  Interesting.

 

But I think that fact it ends up as a back slash is the more important part,  So try using forward slashes instead of back slashes as a workaround.  It's possible the file path parser is treating the back slash as a character escape in Windows python, which might indicate why \bad.bin doesn't work but \good.bin does, since \b is a backspace escape character.

 

I will take a closer look later on, but try that to keep moving forward.

'good.bin' exist and no 'bad.bin'.

The separator is \. I confirm that by selecting some file on file sink block file menu.

How can I check if any unicode?

Kim,

 

That's a very odd error.  Can you confirm that neither good.bin or bad.bin existed in that folder?  Are there any unicode characters in the filename?  Your path separators were copied as \. Can you confirm which direction slashes you were using?

But I still have problem. Some file name works good, but not the another.

 

For ex. 'C:\Work\GRC_Work\good.bin' whithout error,

But 'C:\Work\GRC_Work\bad.bin' fail.

 

It looks like some kind of bug.

Hi Kim,

 

can you try to select an absolute file name rather then just "new.bin", in a directory that you definitely can generate new files in?

To me, this looks like the reason really is that you're not allowed to create or write to new.bin.

 

Best regards,

Marcus

Hi all

 

When I test file sink block on Windows 10 platform, I got permission error. GRC version is 3.7.9.2

This flowgraph works well on Ubuntu environment.

How can I overcome this issue.

 

One more issue is the deference before "Stream to tagged stream" and after.

I want to know what this block meaning.
