Hello, I used ct-ng-1.4.2 to build a toolchain for x86-64. The steps I did: 1. ct-ng x86_64-unknown-linux-gnu 2. Remove java 3. ct-ng build The toolchain was build OK. When I ran "x86_64-unknown-linux-gnu --v" I got: Using built-in specs. Target: x86_64-unknown-linux-gnu Configured with: /home/zvivered/GNU/ct-ng-1.4.2/working/src/gcc-4.3.2/configure --build=i386-build_redhat-linux-gnu --host=i386-build_redhat-linux-gnu --target=x86_64-unknown-linux-gnu --prefix=/home/zvivered/GNU/ct-ng-1.4.2/release_64 --with-sysroot=/home/zvivered/GNU/ct-ng-1.4.2/release_64/x86_64-unknown-linux-gnu//sys-root --enable-languages=c,c++ --disable-multilib --with-gmp=/home/zvivered/GNU/ct-ng-1.4.2/release_64 --with-mpfr=/home/zvivered/GNU/ct-ng-1.4.2/release_64 --with-pkgversion=crosstool-NG-1.4.2 --enable-__cxa_atexit --with-local-prefix=/home/zvivered/GNU/ct-ng-1.4.2/release_64/x86_64-unknown-linux-gnu//sys-root --disable-nls --enable-threads=posix --enable-symvers=gnu --enable-c99 --enable-long-long --enable-target-optspace Thread model: posix gcc version 4.3.2 (crosstool-NG-1.4.2) But when I tried: ldd ld-2.9.so I got: not a dynamic executable I also tried ldd myapp.out which is a very simple executable I created and got the same response. I built a vanilla kernel with this toolchain. But when this kernel searches for init, it can't find one. When I replaced the init with one created with an i686 toolchain it worked fine. Then I looked at build.log and saw some errors starting from line 25150 : [ALL ] objdump: init-first.o: File format not recognized What is the reason for those errors ? By the way, ct-ng is a great tool !!!. I built a toolchain for i686 and it works great. Thanks, Zvika Vered
