I'm building my first OpenWRT Image from buildroot at the time. A couple of Files (uClibc and busybox) are no longer at the original sites for download. I have changed my local Makefile to point to the newest versions of both. The build runs through without errors now.
Wouldn't it be better to point to the "snapshot" file instead of the dated version. This way you always get a download. Of course this could be a problem if a version comes out that is incompatible. The dated versions are removed when they're older than a month or two as far as I could see.
Another thing: It would be nice if the make process ended with something like "OpenWRT built successfully!" or the sort instead of "sed -e "1s,^W54S,W54G," < openwrt-gs-code.bin > openwrt-g-code.bin" like it does now.
Since I'm comfortable with buildroot (I work on different similar projects - OpenEmbedded, OpenSIMpad etc.) this doesn't bother me, but it could be confuse first time users.
