uClinux Busybox build error

Greetings,

I have been working to setup a Nios2 uClinux-dist build environment for the past couple of days. I started with the uClinux-dist-20101026.tar.bz2 download from the wiki pages. I then checked out and updated sources. I have been following the information for implementing the Devicetree configuration. I set the linux-2.6 branch to unstable-nios2mmu per the wiki. I selected all default options in the uClinux-dist configuration. 


nios2-linux/linux-2.6$ git branch
  nios2mmu
  test-nios2
* unstable-nios2mmu
nios2-linux/uClinux-dist$ git branch
  test-nios2
* trunk
The kernel is compiling properly and accepting my DTS. During compilation of busybox, I'm getting the following output and a make error: 


...
  CC      libbb/xrealloc_vector.o
  CC      libbb/xregcomp.o
  AR      libbb/lib.a
  LINK    busybox_unstripped
Trying libraries: crypt m
 Library crypt is not needed, excluding it
 Library m is not needed, excluding it
Final link with: <none>
make: Leaving directory `nios2-linux/uClinux-dist/user/busybox/build-busybox-1.18.4'

make: Leaving directory `nios2-linux/uClinux-dist/user'
make: ***  Error 2
make: Leaving directory `nios2-linux/uClinux-dist/user'
make: ***  Error 1
I've tried both available uClinux-dist branches (test-nios2 and trunk) with the same results. I have been searching for similar problems, but I haven't had much luck finding a resolution. I'm not very familiar with the uClinux build environment so I haven't been able to find any detailed logs to try and get more information about the problem.

Am I missing some devel files for the mentioned libraries? Could there be something wrong in my environment variables?

Any suggestions would be greatly appreciated.

    I never saw this error.. try to manipulate the busybox configurations under the applications tab and see if your error changes. Try to build it as a static lib

    Thanks for the suggestion, aprado. I tried some of the different build options under the busybox menu, but none made a difference.

    To make sure the problem was originating in the busybox component, I disabled it entirely. This allowed me to get further, but I still had errors when trying to find the uuid/uuid.h header. I installed the uuid-dev package (Ubuntu) and was then able to complete a build. This appears to have also been the root cause of the busybox error. After installing uuid-dev and enabling busybox again, everything seems to have built without error.

    good tip aprado......

    it seems to me to be lack dependencies to build the kernel..........

    after you install all dependencies first try to compile with defalt all settings at menuconfig

    good luck

    Thanks! This seemed to fix my problem which looked very similar. I an running on fairly new Ubuntu 12.04 install, but I think I had seen similar problems in the past while building on an Ubuntu 10.10.

    I was getting the same error cited above. Oddly enough, though, the error did not appear every time. I think when I used my own .config files, I avoided this problem, possibly because I was excluded certain parts of the build.

    In any case, it would be good if this package requirements were added to the Wiki if they aren't already.
