[Clfs-support] Linkage error when making uClibc-0.9.31

Wed Mar 30 02:28:00 PDT 2011

Hi forum!

I am trying to build a custom cross-toolchain for my ARM920T S3C2440
following step by step all the useful information explained on the book:

  ==> http://cross-lfs.org/view/clfs-embedded/arm/

I have succesfully compiled and installed on the cross-environ:
  - gmp-5.0.1
  - mpfr-3.0.0
  - mpc-0.8.2
  - binutils-2.21
  - gcc-4.5.2

but the uClibc compilation with 'make' fails at some linking stage.
All the needed information to track that isssue is attached.

Googling for that error, I found some post to fix a similar issue here:

  ==> http://www.mail-archive.com/uclibc@uclibc.org/msg02438.html

But that does not fix the problem for me (still the same problem).

Hope you can help me with that.

Thank you very much for the time spent in writing that USEFUL book!!

Best regards,
