我與下列工具集交叉編譯項目：未解決的符號
- cmake的
- 工具鏈是ARM-Linux的gnueabihf
- SYSROOT（這實際上是必要的rsync從樹莓派2的東西，包含所有的頭文件和庫，我需要）
- 和find_package
加速的名單配置方式如下：
set(CMAKE_CXX_FLAGS ${CMAKE_CPU_FLAGS} "-DBOOST_ALL_DYN_LINK -fPIC -std=gnu++14 ${CMAKE_ARCH}")
set(Boost_DEBUG OFF)
set(Boost_USE_STATIC_LIBS OFF)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
set(BOOST_ALL_DYN_LINK ON) # force dynamic linking for all libraries
set(BOOST_COMPONENTS
system
thread
program_options
regex
filesystem
unit_test_framework
date_time
chrono
log_setup
log
)
set(BOOST_ROOT ${CMAKE_SYSROOT})
set(BOOST_INCLUDEDIR ${BOOST_ROOT}/usr/inc)
set(BOOST_LIBRARYDIR ${BOOST_ROOT}/usr/lib/arm-linux-gnueabihf)
find_package(Boost 1.54.0 REQUIRED COMPONENTS ${BOOST_COMPONENTS})
下OS X編譯和鏈接只是去罰款，我可以送申請書到RPI2並運行它。
問題是在Ubuntu下的鏈接過程。它無法找到夫婦boost.log相關符號：
