This document summarises a few hints for cross-compiling Vanetza’s dependencies. Please note, that cross-compiling is not relevant for you if you plan to use Vanetza on the same system you have built it on.


Create a configuration file for Boost.Build in your home directory at $HOME/user-config.jam and add following line to it:

using gcc : arm : arm-linux-gnueabihf-g++ ;

The install stage does not work in Boost 1.71.0 (and 1.70.0) when cross-compiling. A workaround for this issue is to remove following lines from tools/build/src/tools/common.jam (around line 976):

# From GCC 5, versioning changes and minor becomes patch
if $(tag) = gcc && [ numbers.less 4 $(version[1]) ]
    version = $(version[1]) ;

# Ditto, from Clang 4
if ( $(tag) = clang || $(tag) = clangw ) && [ numbers.less 3 $(version[1]) ]
    version = $(version[1]) ;

Then, the required libraries can be built and installed at given prefix path:

./b2 --prefix=$HOME/vanetza-deps --with-date_time --with-program_options --with-system --no-samples --no-tests variant=release link=shared cxxstd=11 install


Version 8.2 can be cross-compiled with the provided GNUmakefile-cross makefile.

export CXX=arm-linux-gnueabihf-g++
export PREFIX=$HOME/vanetza-deps
make -f GNUmakefile-cross shared
make -f GNUmakefile-cross install


Following steps have been tested with version 1.50. $VANETZA refers to the root directory of this repository.

mkdir build.arm
cd build.arm
cmake .. -DCMAKE_TOOLCHAIN_FILE=$VANETZA/cmake/Toolchain-Cohda-MK5.cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=$HOME/vanetza-deps
make install
