arm-xc-armv5tejl. ARM CrossCompile image for armv5tejl

Image with tools for crosscompile for the particular arm architecture armv5tejl

Build

$ docker build -t scarrascoh/arm-xc-v5tejl:1.23.0 .

Note: Image compilation may take one hour.

Run

$ docker run -ti --name arm-xc-v5tejl \
  scarrascoh/arm-xc-v5tejl:1.23.0 bash

Usage

Binaries for cross-compile for ARM v5tejl are located on /home/arm/x-tools (and executables included in PATH environment)

Note: Tar files (that are downloaded by ct-ng by default) are provided inside config folder in order to allow a fastest compilation of build image.

About crosstool-ng

This docker images uses crosstool-ng as toolchains for generate binaries for cross-compiling. You can find more info about it at their site crosstool-ng.org

Appendix A. How to build OpenSSH for ARM

export PATH="${PATH}:$WORKDIR/../x-tools/armv5tejl-unknown-linux-gnueabi/bin:${XTOOLNG_DIR}/bin"
export HOST=armv5tejl-unknown-linux-gnueabi
export ROOTFS=/home/arm/ssh-server/build
export SYSROOT=/home/arm/x-tools/armv5tejl-unknown-linux-gnueabi

Compile zLib (v1.2.8)

cd ~/ssh-server/zlib-1.2.8 AR=$HOST-ar CC=$HOST-gcc RANLIB=$HOST-ranlib ./configure --prefix=$ROOTFS/usr make make install

Build openssl (v1.0.1e)

cd ~/ssh-server/openssl-1.0.1e ./Configure linux-armv4 shared zlib --prefix=$ROOTFS/usr --with-zlib-include=$ROOTFS/usr/include --with-zlib-lib=$ROOTFS/usr/lib make CC=$HOST-gcc AR="$HOST-ar r" RANLIB=$HOST-ranlib make CC=$HOST-gcc AR="$HOST-ar r" RANLIB=$HOST-ranlib INSTALL_PREFIX=$ROOTFS install

Build openssh (v6.4p1)

Step 1

cd ~/ssh-server/openssh-6.4p1
./configure --host=$HOST --prefix=$ROOTFS/usr --with-zlib=$ROOTFS/usr --with-ssl-dir=$ROOTFS/usr

Note: If an openssl headers not found is thrown, check that openssl libraries were created under $ROOTFS/usr instead of $ROOTFS/usr/home/...

Step 2. Remove the variable STRIP_OPT(or set value to "") and check-config in the rule install_files and install in Makefile.

Step 3

make && make DESTDIR=$ROOTFS install

Generate ssh keys for server

ssh-keygen -t rsa1 -f $ROOTFS/usr/etc/ssh_host_key -N ""
ssh-keygen -t dsa -f $ROOTFS/usr/etc/ssh_host_dsa_key -N ""
ssh-keygen -t rsa -f $ROOTFS/usr/etc/ssh_host_rsa_key -N ""
ssh-keygen -t ecdsa -f $ROOTFS/usr/etc/ssh_host_ecdsa_key -N ""

Copy required libraries with binaries under $ROOTFS (if target system does not have it)

cp /home/arm/x-tools/armv5tejl-unknown-linux-gnueabi/armv5tejl-unknown-linux-gnueabi/sysroot/lib/* $ROOTFS/usr/lib/
