Try a flavor of *nix.
This section takes Linux as an example to introduce the installation process. Other systems are similar;
System Requirements
- The Linux kernel should be not lower than 2.6.9, 64-bit version;
- The gcc version is not less than 5.4.0;
- Use cmake as the build tool, and the cmake version should be not less than 3.5;
- Use git as the version management tool;
Library Dependencies
- trantor, a non-blocking I/O C++ network library, also developed by the author of Drogon, has been used as a git repository submodule, no need to install in advance;
- jsoncpp, JSON's c++ library, the version should be no less than 1.7;
- libuuid, generating c library of uuid;
- zlib, used to support compressed transmission;
- OpenSSL, not mandatory, if the OpenSSL library is installed, drogon will support HTTPS as well, otherwise drogon only supports HTTP.
- c-ares, not mandatory, if the c-ares library is installed,drogon will be more efficient with DNS;
- libbrotli, not mandatory, if the libbrotli library is installed, drogon will support brotli compression when sending HTTP responses;
- boost, the version should be no less than 1.61, is required only if the C++ compiler does not support C++ 17.
- the client development libraries of postgreSQL, mariadb and sqlite3, not mandatory, if one or more of them is installed, drogon will support access to the according database.
- gtest, not mandatory, if the gtest library is installed, the unit tests can be compiled.
System Preparation Examples
Ubuntu 18.04
Environment
sudo apt install git
sudo apt install gcc
sudo apt install g++
sudo apt install cmake
jsoncpp
sudo apt install libjsoncpp-dev
uuid
sudo apt install uuid-dev
OpenSSL
sudo apt install openssl
sudo apt install libssl-dev
zlib
sudo apt install zlib1g-dev
CentOS 7.5
Environment
yum install git
yum install gcc
yum install gcc-c++
The default installed cmake version is too low, use source installation
git clone https://github.com/Kitware/CMake
cd CMake/
./bootstrap && make && make install
Upgrade gcc
yum install centos-release-scl
yum install devtoolset-8
scl enable devtoolset-8 bash
Note: Command scl enable devtoolset-8 bash
only activate the new gcc temporarily until the session is end. If you want to always use the new gcc, you could run command echo "scl enable devtoolset-8 bash" >> ~/.bash_profile
, system will automatically activate the new gcc after restarting.
jsoncpp
git clone https://github.com/open-source-parsers/jsoncpp
cd jsoncpp/
mkdir build
cd build
cmake ..
make && make install
uuid
yum install libuuid-devel
OpenSSL
yum install openssl-devel
zlib
yum install zlib-devel
Database Environment
Note: These libraries below are not mandatory. You could choose to install one or more database according to your actual needs.
Note: If you want to develop you webapp with database, please install the database develop environment first, then install drogon, otherwise you will encounter a NO DATABASE FOUND
issue.
PostgreSQL
PostgreSQL's native C library libpq needs to be installed. The installation is as follows:
ubuntu 16
:sudo apt-get install postgresql-server-dev-all
ubuntu 18
:sudo apt-get install postgresql-all
centOS 7
:yum install postgresql-devel
MacOS
:brew install postgresql
MySQL
MySQL's native library does not support asynchronous read and write. Fortunately, MySQL also has a version of MariaDB maintained by the original developer community. This version is compatible with MySQL, and its development library supports asynchronous read and write. Therefore, Drogon uses the MariaDB development library to provide the right MySQL support, as a best practice,your operating system shouldn't install both Mysql and MariaDB at the same time.
MariaDB installation is as follows:
ubuntu
:sudo apt install libmariadbclient-dev
centOS 7
:yum install mariadb-devel
MacOS
:brew install mariadb
Sqlite3
ubuntu
:sudo apt-get install libsqlite3-dev
centOS
:yum install sqlite-devel
MacOS
:brew install sqlite3
Note: Some of the above commands only install the development library. If you want to install a server also, please use Google search yourself.
Drogon Installation
Assuming that the above environment and library dependencies are all ready, the installation process is very simple;
cd $WORK_PATH
git clone https://github.com/an-tao/drogon
cd drogon
git submodule update --init
mkdir build
cd build
cmake ..
make && sudo make install
The default is to compile the debug version. If you want to compile the release version, the cmake command should take the following parameters:
cmake -DCMAKE_BUILD_TYPE=Release ..
After the installation is complete, the following files will be installed in the system(One can change the installation location with the CMAKE_INSTALL_PREFIX option):
- The header file of drogon is installed into /usr/local/include/drogon;
- The drogon library file libdrogon.a is installed into /usr/local/lib;
- Drogon's command line tool drogon_ctl is installed into /usr/local/bin;
- The trantor header file is installed into /usr/local/include/trantor;
- The trantor library file libtrantor.a is installed into /usr/local/lib;
Include drogon source code locally
Of course, you can also include the drogon source in your project. Suppose you put the drogon under the third_party of your project directory (don't forget to update submodule in the drogon source directory). Then, you only need to add the following two lines to your project's cmake file:
add_subdirectory(third_party/drogon)
target_link_libraries(${PROJECT_NAME} PRIVATE drogon)
Use vcpkg
The easiest way to install drogon on windows is to use vcpkg
vcpkg.exe install drogon
Or
vcpkg.exe install drogon:x64-windows
if you haven't install vcpkg:
-
Assuming that you don't have
cmake.exe
,make.exe
andvcpkg.exe
-
Make it sure you're already install
git
for windows too -
First, go to where you want to install
vcpkg
.- In this case, we're gonna use
C:/Dev
directory. - If you don't have that directory yet, open your powershell as administrator:
- type and enter:
cd c:/
mkdir Dev;cd Dev;
mean you will create dev and go to dev directorygit clone https://github.com/microsoft/vcpkg
cd vcpkg
./bootstrap-vcpkg.bat
this will installvcpkg.exe
- note: to update your vcpkg, you just need to type
git pull
- to make it sure that vcpkg directory always able to access:
- add
C:/dev/vpckg
to your windows environment variables.
- add
- restart/re-open your powershell
- type and enter:
- In this case, we're gonna use
-
Now check if vcpkg already installed properly, just type
vcpkg
orvcpkg.exe
-
To install drogon framework. Type:
- 32-Bit:
vcpkg install drogon
- 64-Bit:
vcpkg install drogon:x64-windows
- wait till all dependencies are installed.
- note:
- if there's any package is/are uninstalled and you got error, just install that package. e.g.:
- zlib :
vcpkg install zlib
orvcpkg install zlib:x64-windows
for 64-Bit
- zlib :
- to check what already installed:
vcpkg list
- if there's any package is/are uninstalled and you got error, just install that package. e.g.:
- 32-Bit:
-
To add drogon_ctl command and dependencies, you need to add some variables. By following this guide, you just need to add:
C:\Dev\vcpkg\installed\x64-windows\tools\drogon
C:\Dev\vcpkg\installed\x64-windows\bin
C:\Dev\vcpkg\installed\x64-windows\lib
C:\Dev\vcpkg\installed\x64-windows\include
to your windows environment variables.
-
reload/re-open your powershell, then type:
drogon_ctl
ordrogon_ctl.exe
- press enter
- if:
usage: drogon_ctl [-v | --version] [-h | --help] <command> [<args>] commands list: create create some source files(Use 'drogon_ctl help create' for more information) help display this message press Do stress testing(Use 'drogon_ctl help press' for more information) version display version of this tool
showed up, you are good to go.

Note:
- you need to be familiar with building cpp libraries by using:
- independent
gcc
org++
or - Microsoft Visual Studio compiler
- independent
- you need to be familiar with building cpp libraries by using:
Use Docker Image
We also provide a pre-build docker image on the docker hub. All dependencies of Drogon and Drogon itself are already installed in the docker environment, where users can build Drogon-based applications directly.

Hello Sir, I am a Windows user and failed to find a solution for the installation of Drogon on windows on this page. Hope you'll help me to find out a solution. regards.
