Crow/docs/getting_started/setup.md

This page explains how to set Crow up for use with your project.

##Requirements

• C++ compiler with C++14 support.
  • Continuous Testing on g++-9.3 and clang-7.0, AMD64 (x86_64) and Arm64 v8
• boost library (1.70 or later).
• (optional) CMake and Python3 to build tests and/or examples.
• (optional) Linking with jemalloc/tcmalloc is recommended for speed.
  
  

##Installing Requirements ###Ubuntu sudo apt-get install libboost-all-dev

###OSX brew install boost

###Windows Download boost from here and install it

##Downloading Either run git clone https://github.com/mrozigor/crow.git or download crow_all.h from the releases section. You can also download a zip of the project on github.

##Includes folder

1. Copy the /includes folder to your project's root folder.
2. Add #!cpp #include "path/to/includes/crow.h" to your .cpp file.
3. For any middlewares, add #!cpp #include "path/to/includes/middlewares/some_middleware.h".
   
   

##Single header file If you've downloaded crow_all.h, you can skip to step 4.

1. Make sure you have python 3 installed.
2. Open a terminal (or cmd.exe) instance in /path/to/crow/scripts.
3. Run python merge_all.py ../include crow_all.h (replace / with \ if you're on Windows).
4. Copy the crow_all.h file to where you put your libraries (if you don't know where this is, you can put it anywhere).
5. Add #!cpp #include "path/to/crow_all.h" to your .cpp file.
   
   Note: All middlewares are included with the merged header file, if you would like to include or exclude middlewares use the -e or -i arguments.
   
   

##building via CLI To build a crow Project, do the following:

###GCC (G++)

• Release: g++ main.cpp -lpthread -lboost_system.
• Debug: g++ main.cpp -ggdb -lpthread -lboost_system -D CROW_ENABLE_DEBUG.
• SSL: g++ main.cpp -lssl -lcrypto -lpthread -lboost_system -D CROW_ENABLE_SSL.

###Clang

• Release: clang++ main.cpp -lpthread -lboost_system.
• Debug: clang++ main.cpp -g -lpthread -lboost_system -DCROW_ENABLE_DEBUG.
• SSL: clang++ main.cpp -lssl -lcrypto -lpthread -lboost_system -DCROW_ENABLE_SSL.

###Microsoft Visual Studio Help needed

##building via CMake Add the following to your CMakeLists.txt:

find_package(Threads)
find_package(OpenSSL)

if(OPENSSL_FOUND)
	include_directories(${OPENSSL_INCLUDE_DIR})
endif()

if (NOT CMAKE_BUILD_TYPE)
	message(STATUS "No build type selected, default to Release")
	set(CMAKE_BUILD_TYPE "Release")
endif()

if (MSVC)
	set(Boost_USE_STATIC_LIBS "On")
	find_package( Boost 1.70 COMPONENTS system thread regex REQUIRED )
else()
	find_package( Boost 1.70 COMPONENTS system thread REQUIRED )
endif()

include_directories(${Boost_INCLUDE_DIR})

set(PROJECT_INCLUDE_DIR ${PROJECT_SOURCE_DIR}/include)

include_directories("${PROJECT_INCLUDE_DIR}")

Note: The last 2 lines are unnecessary if you're using crow_all.h.

##Building Crow tests and examples Out-of-source build with CMake is recommended.

mkdir build
cd build
cmake ..
make

Running Cmake will create crow_all.h file and place it in the build directory.

You can run tests with following commands:

ctest -V
