errors you may encounter

• Using Ubuntu 8.10, early on you may get errors like: cc1: warnings being treated as errors
  • I installed gcc-4.1 to get by this as described in this thread: http://www.nabble.com/Package-binutils-failed-building-Helloworld-tutorial-and-new-image-td20457568.html
• Later, with Ubuntu 8.10, errors compiling dbus-native:
  • error -- NOTE: package dbus-native-1.0.3-r0: task do_compile: failed
  • bug recorded here -- http://bugs.openembedded.net/show_bug.cgi?id=4334
  • solution -- http://bugs.openembedded.net/attachment.cgi?id=13733
• Problems with readline (checksum error)
  • probably related to the source url sucking and the file not downloading all the way or something
  • go into sources and remove any readline stuff
  • run bitbake bug-image-production again, but hit Ctr-C twice when it tries to dl readline
  • the third repo it settles on will work
  • after that works run bitbake again
