Building

Prereqs

Boost

On OSX:

 brew install gcc49 wget
 source ./ci/install_boost.sh
 ./ci/build_boost.sh
 export DYLD_LIBRARY_PATH=$BOOST_ROOT/stage/lib

On Windows:

  • Ensure gcc is in your path (e.g. from MinGW). Tested on version 4.9.3.
  • Download boost 1.61.0 from sourceforge and xtract to a folder.
  • Define BOOST_ROOT to point to the folder containing boost, e.g.
set BOOST_ROOT=c:\dev\boost_1_61_0

Then build the boost libraries

cd %BOOST_ROOT%
bootstrap.bat gcc
bjam --install --layout=tagged --with-system --with-program_options --with-random --with-thread toolset=gcc

Building the Virtual Device

cd main
make -s PRODUCT_ID=3

The resulting executable is placed in build/target/main/platform-3/main.

Device Configuration

Configuration Sources

The device can be configured using any of these sources:

  • command line arguments: to see the list of command line arguments supported, run with --help
  • configuration file: the file vdev.conf is read from the current directory if it exists.
  • environment variables: the names above are turned into environment variables by making them uppercase, and prefixing with VDEV_. For example, the device id is configured with the environment variable VDEV_DEVICE_ID

Configuration Values

The virtual device is configured using keys and values.

Name Description
device_id the unique ID for this device, maximum 12 digits
device_key the file containing the device's private key
server_key the file containing the cloud public key
protocol tcp or udp

Troubleshooting

Build

Duplicate sections that are different sizes.

  • the same templates are linked into different boost libraries, producing different compiler output. This can be due to different compiler flags. Use -n -a flags with bjam to see the tool invocations and compare flags.
