I have removed the "zlib" folder from "gcc-linaro-4.8-2014.03.tar.xz" tarball, the compiler is also using zlib-1.2.5 statically linked, and thats permit compile the Linaro toolchain.

Problem building arm toolchain for x86_64 host system

by Alexis Fajardo Moya

Hello, I have a problem building gcc-linaro-arm-linux-gnueabihf toolchain for my x86_64 system. I download crosstool-ng (v1.13) and toolchain source code (4.8-2014.03) from http://releases.linaro.org/14.03/components/toolchain/binaries. I use the example configuration linaro-arm-linux-gnueabihf (obtained from ct-ng list-samples) and modify some entries using menuconfig option, like the local tarballs directory (pointing to downloaded toolchains source code directory) and the prefix directory (custom directory output). This is the problem during the execution of "ct-ng build" command: ================================================================= [INFO ] Installing final compiler [EXTRA] Configuring final compiler [EXTRA] Building final compiler [EXTRA] AFMOYA: EMPIEZA A EJECUTARSE make jobsflags all [EXTRA] -j5 [EXTRA] /home/afmoya/Descargas/build/.build/arm-linux-gnueabihf/build/build-cc [ERROR] configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.
