cant open apps after installation

[bmarkus]

Start FF in a terminal window. What are the messages?

[mebius]

"Invalid command" sorry "illegal instruction"

[Juanito]

did you type "FF" or "firefox"?

[mebius]

I type firefox. If I type FF then "sh:FF: not found"

[Juanito]

what sort of cpu are you using (i486, i686, etc)?

what does "uname -a" give?

[mebius]

tc@box:~$ uname -a
Linux box 3.16.6-tinycore #777 SMP Thu Oct 16 90:42:42 UTC 2014 i686 GNU/Linux

I use VIA EPIA-5000A MiniATX

[Juanito]

firefox say:

Intel Pentium II or AMD K6-III+ 233 MHz CPU

..perhaps that is the source of the illegal instruction message?

does the controlpanel gui "system stats" cpu tab give any more info on your cpu?

It's difficult to know exactly, but I'd guess firefox expects one or more cpu functions to be available that your cpu doesn't have...

[mebius]

Thank you, Juanito. It's maybe true.
