I know, I know, I'm trying to compile an old and unsupported version, alas upgrading is not an option.
I'm doing some research with older devices and as such I'm stuck with older versions as well. I'm able to create an image using the image builder and this works okay as I wasn't expecting to loose the webui in the process but at least it isn't bricked.
This made me want to be able to test the image before flashing. The target device is a WRT54GL and as such the arch is mipsel. In a later version the Malta target has been added specifically to test such images in Qemu. So I figured to attempt to backport that target, seems like the code base is modular enough to allow this.
So before doing that I want to compile OpenWrt from source just to see if it works before messing with it. I'm running Ubuntu 11.10 in a VM and cloned the OpenWrt archive (https://git.openwrt.org/openwrt/svn-archive/archive.git) that contains the 10.03.1 release (f79d3e781c0dbc2c259ecd4aa8eefb51a1bd28b6). I've copied the .config from the image builder and ran make menuconfig to check if the config actually works. After manually downloading some sources and putting them in the dl dir it starts to compile. But I cannot seem to be able to build crda for some reason.
Below is the output I get when running make package/crda/compile V=99:

In my experience these errors are bogus and the fault is somewhere else. I have limited C knowledge but can tell that the sources seem fine and there is no visual 'syntax error'. If you want to look at the source: http://ftp.iij.ad.jp/pub/linux/kernel/software/network/crda/crda-1.1.1.tar.bz2 (or pick another mirror).
As some of the errors are related to __be32 and it wasn't syntax highlighted I took a look at that. The type (it's a type, right?) needs to be defined and should be included from linux/types.h. Checking the include dirs reported by the make command I can find one types.h but it doesn't seem to have a typedef for __be32. I did find another types.h with the __be32 typedef but including that doesn't seem to change anything. I've stripped the file (build_dir/linux-brcm-2.4/crda-1.1.1/include/linux/types.h) down to this:
#include <linux/posix_types.h>
#include <asm/types.h>
typedef __u32 __bitwise __be32;
Again no luck and I'm out of ideas, can you help me?
