Hi there,

I'm new to Linux, new to OpenWrt and new to this forum, so please be patient with me :-)
I have flashed my ASUS WL-500gP V2 with BackFire 10.03.1 ans installed some packages for USB storage & Bluetooth.
I installed a space PC with Ubuntu 10.10
So far, so good... here comes my problem:
I want to build the Backfire 10.03.1 SDK to cross compile a HelloWorld example.
So I downloaded the SDK (OpenWrt-SDK-brcm47xx-for-Linux-i686-gcc-4.3.3+cs_uClibc-0.9.30.1.tar.bz2) from http://backfire.openwrt.org/10.03.1/brcm47xx/
I took these pages as an example:
http://manoftoday.wordpress.com/2007/10 … r-openwrt/
and
http://dwienie.co.cc/index.php/De-cross-compiler.html (in dutch)

After installing the dependencies like ncurses, flex etc I run make menuconfig. It compiles, but this is all I get:

Can someone explain me what"s wrong? I've searched this forum to get a clue, but being new to all this, I'm totally lost now.
Please help me.

Thanks

This happens if the (hidden) .config file got deleted, did you run "make clean" or a similar command after unpacking the SDK?

Thanks jow for the quick reply!

No, the .config is there...
Here's a part of it: (it's too big to post it here +/- 5000 lines)

I did the download/extract again and no change.

erm, ok. Well you're not supposed to use make menuconfig in the SDK. It is already compiled so you cannot change anything anyway. Simply run "make V=99" to build all packages in package/ or use make package/name/{clean,compile} V=99 to build selected ones explicitely.

Before running into other weird issues down the road; there is currently a relocatabilty problem with the SDK [1], you'll probably need to install a symlink "/home/jow/devel/openwrt/10.03.1/brcm47xx" to the topdir of the SDK.

Thanks jow, I think I was mislead by printscreen & explanation on this Dutch site: http://dwienie.co.cc/index.php/De-cross-compiler.html to change "Target Profile"
For now, it won't compile, but I will have a look myself first, as this is the way I want to learn ;-)

OK, got it working. Thanks again.

The discussion might have continued from here.
