I wrote a free pascal program in ubuntu Linux and wanted to deploy it to run in a netgear router through open router firmware OpenWrt. To test it, I copied the program into a OpenWrt virtualbox virtual machine but when I ran it, it said:
[ 1891.890545] MyprogramName[1573] general protection ip:bf8e3f86 sp:bf8e2cd4 error:0 Segmentation fault

I suspect it's because my compile target is wrong but I thought OpenWrt is already based on linux.
Please, in the CPU family, I cannot find the one used by Netgear router which is Atheros AR7161

Can anyone give me some directions ?

Thanks a lot.

Just to keep things going since I'm in no way an expert: Google suggests that's MIPS24k, what's the output from cat /proc/cpuinfo on that box? What does the file command have to say about your binary? What version of FPC are you using?

AFAIK VirtualBox is Intel x86 and AMD64 compatible. It will not run code for any other architecture. I couldn't understand your post but if you're trying to run MIPS code under VirtualBox, it will not work no matter what OS.

Then again maybe I am wrong and somebody ported VirtualBox to MIPS...

I did some search and it seems the CPU Atheros used by Netgear is MIPS. I will try to learn how to cross compile into MIPS. If it does not work on the virtual box, I will try to run it directly in the router via ssh. (the virtual box virtual machine image was provided by the OpenWrt web site. The machine ran ok, just not ok with my free pascal compiled program).

Thanks for all your feedback.
