indoorjson3-cpp

indoorjson3 serialization and desrialization library writen in c++14

Introduction

A experimental project tring to redesign IndoorGML concept to make it easy to use. And add transport system support.

Depedencies

json-schema-validator/2.2.0

We use json-schema-validator to define and validate the json string which uses nlohmann/json

geos/3.12.0

We use libgeos to represent the Geometry of CellSpace and CellBoundary.

glog/0.6.0

for logging

gtest/1.14.0

for unit tests.

Build

install dependencies manually (Ubuntu 22.04)

1. install using apt

sudo apt install libglog
sudo apt install libgoogle-glog-dev
sudo apt install libgtest-dev
sudo apt install nlohmann-json3-dev

2. install from source code

   1. json-schema-validator

   No apt sources are available for it, so we need to build it from source code

   git clone https://github.com/pboettch/json-schema-validator.git
   cd json-schema-validator
   mkdir build
   cd build
   cmake ..
   make -j16
   make install

   2. libgeos

   The default libgeos version of Ubuntu 22.04 is libgeos 3.10.2 which is not stable enough so we better build if from the source code.

   git clone https://github.com/libgeos/geos.git
   cd geos
   git checkout 3.12.0
   mkdir build
   cd build
   cmake ..  -DBUILD_TESTING=OFF
   make -j16
   sudo make install

3. build indoorjson3-cpp

cd indoorjson3-cpp
mkdir build
cd build
cmake ..
make -j16

install dependencies using conan (Ubuntu 22.04)

1. Install conan first https://conan.io/downloads

2. Use conan to prepare the dependencies and generate cmake files in "build" directory.

conan install . --output-folder=build --build=missing

3. Then use cmake to configure.

cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=conan_toolchain.cmake -DCMAKE_BUILD_TYPE=Release

4. Finally trigger build using make.

make -j16

install dependencies using conan (Windows Visual Studio Community)

1. Install conan first https://conan.io/downloads

2. Use conan to prepare the dependencies and generate cmake files in "out/build" directory.

conan install . --output-folder=out/build --build=missing

3. Open indoorjson3-cpp directory using Visual Studio

4. Set CMakeSettings.json

  "buildRoot": "${projectDir}\\out\\build\\${name}",
  "installRoot": "${projectDir}\\out\\install\\${name}",
  "cmakeToolchain": "${projectDir}\\out\\build\\conan_toolchain.cmake",

5. Finally trigger configuration and building using VS GUI.
