Общая библиотека Conan Boost не найдена

/ 14 апреля 2020

Я пытаюсь настроить проект, используя библиотеку boost из conan-center на linux. Чтобы проверить мою проблему в небольшой среде, я создал проект, который вы можете протестировать.

https://github.com/resqsx/conan-boost

Я тестирую на

  • ubuntu 18.04
  • conan 1.24.0
  • boost 1.72.0

Мой conafile выглядит так: 

[requires]
boost/1.72.0

[options]
boost:shared=True

[generators]
cmake

[imports]
bin, *.dll -> ./bin
lib, *.dylib* -> ./bin
lib, *.so* -> ./bin

И CMake: 

cmake_minimum_required (VERSION 3.12.0)

project(spielwiese)

# Load Conan
include(${CMAKE_SOURCE_DIR}/conan.cmake)
include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)

conan_cmake_run(CONANFILE conanfile.txt
BASIC_SETUP CMAKE_TARGETS BUILD missing)

add_executable(spielwiese spielwiese.cpp)

target_link_libraries(spielwiese CONAN_PKG::boost)

Мой процесс сборки выглядит нормально в соответствии с результатом: 

Configuration:
[settings]
arch=x86_64
arch_build=x86_64
build_type=Release
compiler=gcc
compiler.libcxx=libstdc++11
compiler.version=7
os=Linux
os_build=Linux
[options]
[build_requires]
[env]

Что не так с моей конфигурацией?

Я думаю, что проблема заключается в транзитивных зависимостях некоторых библиотек, таких как от libboost_log до libboost_filesystem.

Эта статья помогла мне понять Как установить RPATH и RUNPATH с GCC / LD ?

Насколько я могу сказать, начиная с Ubuntu 18.04. компоновщик использует RUNPATH вместо RPATH . Но проблема с RUNPATH заключается в том, что загрузчик не использует его для поиска транзитивных зависимостей.

Одним из решений является установка LD_LIBRARY_PATH перед вызовом приложения. Что мне не нравится.

Другой способ - указать cmake для установки с RPATH следующим образом: 

set(CMAKE_EXE_LINKER_FLAGS "-Wl,--disable-new-dtags")

И затем установить желаемый путь к библиотеке "." или что вы хотите. 

set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -Wl,-rpath -Wl,.")

Вы можете увидеть разницу, используя readelf -d Когда все в порядке, это должно выглядеть следующим образом. Использование RPATH

В противном случае при настройке с помощью RUNPATH это выглядит так
