# Cross-Compilation of Dependencies
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
|
||
|
|
## Boost
|
||
|
|
|
||
|
|
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 = $(version[1]) ;
|
||
|
|
}
|
||
|
|
|
||
|
|
Then, the required libraries can be built and installed at given *prefix* path:
|
||
|
|
|
||
|
|
:::shell
|
||
|
|
./b2 --prefix=$HOME/vanetza-deps --with-date_time --with-program_options --with-system --no-samples --no-tests variant=release link=shared cxxstd=11 install
|
||
|
|
|
||
|
|
|
||
|
|
## Crypto++
|
||
|
|
|
||
|
|
Version 8.2 can be cross-compiled with the provided `GNUmakefile-cross` makefile.
|
||
|
|
|
||
|
|
:::shell
|
||
|
|
export CXX=arm-linux-gnueabihf-g++
|
||
|
|
export PREFIX=$HOME/vanetza-deps
|
||
|
|
export HAS_SOLIB_VERSION=1
|
||
|
|
make -f GNUmakefile-cross shared
|
||
|
|
make -f GNUmakefile-cross install
|
||
|
|
|
||
|
|
|
||
|
|
## GeographicLib
|
||
|
|
|
||
|
|
Following steps have been tested with version 1.50.
|
||
|
|
`$VANETZA` refers to the root directory of this repository.
|
||
|
|
|
||
|
|
:::shell
|
||
|
|
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
|
