Thanks Hoovah!

Such a simple-but-powerful suggestion.

I've attached a VI with an example of the workaround, in case anyone is interested in exactly what I ended up doing to get it to unzip.

Unzip file (RT with SysExec).vi

Hi all,

I've got a customer that wants to zip/unzip files on their cRIO-9035, so I had them playing with the OpenG Zip tools to see if it would fit their needs. Although they've found that they can zip files on their cRIO just fine, they find that they get disconnected from their RT target and the shell shows the following error message:

LabVIEW caught a fatal signal
15.0 - Recieved SIGSEGV
Reason: address not mapped to object
Attempt to reference address: 0x0x10000000
stdin: is not a tty

The zip file they're testing with includes two simple .txt files with short strings in them ("booya" and "booya2"). This file unzips just fine on the host PC with the "ZLIB Extract All Files To Dir" VI, but when copied over to the cRIO and unzipped via the same VI, it only unzips the first text file and the resulting file doesn't have any text in it.

I've attached a copy of the project and the zip file I used to reproduce this behavior using a cRIO-9033 that I had on hand. (The only thing I can't provide is the cRIO >_<)

Could anybody tell me what I'm doing wrong? Any suggestions as to what other workarounds I could take to zip/unzip files on a LinuxRT target would also be very much appreciated!

Regards,

Tamon
