C Program doesn't run on openwrt Backfire 10.03

Hi all,
We are trying to compile a helloworld package writted in C and downloaded from the following tutorial: http://manoftoday.wordpress.com/2007...m-for-openwrt/

We have the RouterStation Pro with Backfire 10.03 from the link: http://downloads.openwrt.org/backfir...sysupgrade.bin

root@OpenWrt:~# uname -a

Linux OpenWrt 2.6.32.10 #20 Tue Apr 6 15:01:26 CEST 2010 mips GNU/Linux


The cross-compilation of the package is done selecting:
Target System (Atheros AR71xx/AR7240/AR913x)
Target Profile (Ubiquiti RouterStation Pro)
The other parameters are set by default

The helloworld C package (.ipk) is correctly compiled, copied to the routerstation pro and installed on it, but when we try to run the program we get:
root@OpenWrt:~# helloworld

/bin/helloworld: line 1: syntax error: unexpected "("

Any idea?

That error typically occurs when you try to execute an x86 binary on an ARM system. It appears that the "cross-compilation" part of your process did not perform as advertised.

I run the file command in two binaries, one original from Backfire, and my helloword to see the differences, and you are right, the cross-compiling doesn't work. Any idea to fix this?

Did you follow the instructions to create "helloworld_1_mipsel.ipk"?
