can't get boost asio working #356

Open cambp4 opened 2 years ago

cambp4 commented 2 years ago

Hi,

I'm trying to get boost asio working. I tried setting it up with the examples you gave. I tried with boost and with the asio standalone, none of which work.

It seems like cmake is downloading and putting things in my build folder, I can see folders related to boost or asio.

However when I compile a simple project that requires 

#include <boost/asio.hpp>
// #include "asio.hpp"

I cannot compile it because it can't find boost asio.

this is my cmake

set (THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)

CPMAddPackage("gh:chriskohlhoff/asio#asio-1-18-1@1.18.1")
if(asio_ADDED)
  add_library(asio INTERFACE)
  target_include_directories(asio SYSTEM INTERFACE ${asio_SOURCE_DIR}/asio/include)
  target_compile_definitions(asio INTERFACE ASIO_STANDALONE ASIO_NO_DEPRECATED)
  target_link_libraries(asio INTERFACE Threads::Threads)
endif()

add_library(FrameworkLibrary
        src/framework/event_manager/EventManager.cpp
        src/framework/event_manager/ControllerInterface.cpp
        src/framework/timer/TimerInterface.cpp
        src/framework/event_manager/SensorsActuatorsAndControllers.cpp
        src/framework/event_manager/EventDataStore.cpp
        src/framework/state_machine/State.cpp
        src/framework/logging/Logger.cpp
        src/framework/timer/Timer.cpp
        src/framework/event_manager/DelayTimer.cpp
        )
target_link_libraries(FrameworkLibrary
    PUBLIC
        Threads::Threads
        # Boost::asio
        asio
    )

I managed to get boost asio working in the end, I had to add this in my cmake:

set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
CPMAddPackage(
  NAME Boost
  VERSION 1.77.0
  GITHUB_REPOSITORY "boostorg/boost"
  GIT_TAG "boost-1.77.0"
)
if(Boost_ADDED)
    message("boost asio downloaded at " ${Boost_SOURCE_DIR}/libs/asio/include)

    file(GLOB files "${Boost_SOURCE_DIR}/libs/*/include")
    foreach(filename ${files})
        include_directories(${filename})
    endforeach()

    file(GLOB files "${Boost_SOURCE_DIR}/libs/*/*/include")
    foreach(filename ${files})
        include_directories(${filename})
    endforeach()
endif()

I've made this to use standalone asio: asio.cmake

set(ASIO_REPOSITORY
    "https://github.com/chriskohlhoff/asio"
    CACHE STRING "Repository of asio"
)
set(ASIO_TAG
    "asio-1-18-2"
    CACHE STRING "Git tag of asio"
)

set(ASIOCMAKE_REPOSITORY
    "https://github.com/OlivierLDff/asio.cmake"
    CACHE STRING "Repository of asio.cmake"
)
set(ASIOCMAKE_TAG
    "v1.1.1"
    CACHE STRING "Git tag of asio.cmake"
)

include(cmake/CPM.cmake)

CPMAddPackage(
  NAME asiocmake
  GIT_REPOSITORY ${ASIOCMAKE_REPOSITORY}
  GIT_TAG ${ASIOCMAKE_TAG}
  OPTIONS "ASIO_USE_CPM ON"
)

The fasted way I know to build boost is to use boost-cmake :

# ---- Add dependencies via CPM ----
# see https://github.com/cpm-cmake/CPM.cmake for more info

include(cmake/CPM.cmake)

# PackageProject.cmake will be used to make our target installable
CPMAddPackage("gh:TheLartians/PackageProject.cmake@1.9.0")

if(EXISTS "$ENV{HOME}/.cache/CPM/boost_1_79_0")
  set(FETCHCONTENT_SOURCE_DIR_BOOST "$ENV{HOME}/.cache/CPM/boost_1_79_0" CACHE PATH "Boost source DIR")
endif()

CPMAddPackage(
  NAME boost-cmake GITHUB_REPOSITORY ClausKlein/boost-cmake
  GIT_TAG b7c741f42b089117221622c72783d2cb821843dc # feature/upgrade-to-boost-v1.79-0
)

target_link_libraries(
    tftpd PUBLIC Boost::filesystem Boost::boost
)
