Conan C++ Package Manager

by malabdalic++

install conan

sudo apt install python3-pip
pip install conan

looking for library

conan search poco --remote=conancenter
poco/1.8.1
poco/1.9.3
poco/1.9.4

creating a conanfile.txt inside our project’s folder with the following content:

[requires]
 poco/1.9.4

 [generators]
 cmake

Next step: We are going to install the required dependencies and generate the information for the build system:

$ conan profile new default --detect  # Generates default profile detecting GCC and sets old ABI
$ conan profile update settings.compiler.libcxx=libstdc++11 default  # Sets libcxx to C++11 ABI
$ mkdir build && cd build  #create build folder of cmake binary
$ conan install ..           #install libraries
#or conan install .. --settings os="Linux" --settings compiler="gcc"

Now let’s create our build file. To inject the Conan information, include the generated conanbuildinfo.cmake file like this:

 cmake_minimum_required(VERSION 2.8.12)
 project(MD5Encrypter)

 add_definitions("-std=c++11")

 include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)
 conan_basic_setup()

 add_executable(md5 md5.cpp)
 target_link_libraries(md5 ${CONAN_LIBS})
