Hi forum!<br><br>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:<br><br> ==> <a href="http://cross-lfs.org/view/clfs-embedded/arm/">http://cross-lfs.org/view/clfs-embedded/arm/</a><br>
<br>I have succesfully compiled and installed on the cross-environ:<br> - gmp-5.0.1<br> - mpfr-3.0.0<br> - mpc-0.8.2<br> - binutils-2.21<br> - gcc-4.5.2<br><br>but the uClibc compilation with 'make' fails at some linking stage. <br>
All the needed information to track that isssue is attached. <br><br>* Version of the book being used: CLFS Embedded GIT-0.0.1-20110323<br><br>* Host distribution: [Ubuntu 9.04 _Jaunty Jackalope_ - Release i386 (20090420.1)]<br>
