没有规则使目标'/usr/lib/x86_64-linux-gnu/libboost_filesystem.so`

Question

我有 a project 我正在处理，但在尝试添加一些增强功能后我无法让 cmake 工作。我输入

cd build/manual/
cmake ../..
make && make install

我收到以下错误：

taylor@taylor-XPS-13-9365:~/markets/build/manual$ make && make install

这个项目有几个 CMakeLists.txt 文件，因为有 1.) 一个主要的可执行文件 markets/src/main.cpp，2.) 一个静态库，以及 3.) markets/test/ 中的一些单元测试.

首先是 markets/CMakeLists.txt:

cmake_minimum_required(VERSION 3.10)

set(CMAKE_CXX_STANDARD 11 ) # used to be 17
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -O3")
#set(CMAKE_CXX_COMPILER /usr/bin/g++-8) # this is now set externally!
set(CMAKE_INSTALL_PREFIX ${PROJECT_SOURCE_DIR})

set(MARKETS_INSTALL_INCLUDE_DIR ${PROJECT_SOURCE_DIR}/include)
set(MARKETS_INSTALL_BIN_DIR ${PROJECT_SOURCE_DIR}/bin)
set(MARKETS_INSTALL_LIB_DIR ${PROJECT_SOURCE_DIR}/lib)
set(MARKETS_HEADERS_DIR ${PROJECT_SOURCE_DIR}/src/markets)

include_directories(${MARKETS_INSTALL_INCLUDE_DIR})
include_directories(${MARKETS_HEADERS_DIR})

add_subdirectory(src)
add_subdirectory(test)

然后是markets/src/CMakeLists.txt（我认为这是有问题的那个）

cmake_minimum_required(VERSION 3.10)
project(run_backtest)

add_subdirectory(markets)
set(SOURCE_FILES main.cpp)

find_package (Eigen3 3.3 REQUIRED NO_MODULE)
find_library(mysqlcppconn 1.1.12 REQUIRED)
find_package(Boost 1.65.1 REQUIRED COMPONENTS system filesystem)

include_directories(${Boost_INCLUDE_DIRS})
add_executable(run_backtest ${SOURCE_FILES})
target_link_libraries(run_backtest markets Eigen3::Eigen mysqlcppconn ${Boost_LIBRARIES})

install(TARGETS run_backtest DESTINATION ${MARKETS_INSTALL_BIN_DIR})

然后是markets/src/markets/CMakeLists.txt

cmake_minimum_required(VERSION 3.10)
project(markets)### C CXX)

set(SOURCE_FILES
    data_handlers.h
    data_handlers.cpp
    data_readers.h
    data_readers.cpp
    execution_handler.h
    execution_handler.cpp
    fill.h
    fill.cpp
    instrument.h
    instrument.cpp
    market_bar.h
    market_bar.cpp
    market_snapshot.h
    market_snapshot.cpp
    order.h
    order.cpp
    pnl_calculator.h
    pnl_calculator.cpp
    portfolio.h
    portfolio.cpp
    position_summary.h
    position_summary.cpp
)

#set(Boost_USE_STATIC_LIBS OFF)
#set(Boost_USE_MULTITHREADED ON) # maybe off?
#set(Boost_USE_STATIC_RUNTIME OFF)

find_package(Boost 1.65.1 REQUIRED COMPONENTS system filesystem)
find_package (Eigen3 3.3 REQUIRED NO_MODULE)
find_library(mysqlcppconn 1.1.12 REQUIRED)

include_directories(${Boost_INCLUDE_DIRS})
link_directories( ${Boost_LIBRARY_DIRS})

add_library(markets SHARED STATIC ${SOURCE_FILES})
target_link_libraries(markets Eigen3::Eigen mysqlcppconn, ${Boost_LIBRARIES})

# not sure if i need this
target_link_libraries( markets ${Boost_FILESYSTEM_LIBRARY}, ${Boost_SYSTEM_LIBRARY})

install(TARGETS markets DESTINATION ${MARKETS_INSTALL_LIB_DIR})

我很确定它抱怨的这个文件存在，所以我不确定该怎么做：

taylor@taylor-XPS-13-9365:~$ stat /usr/lib/x86_64-linux-gnu/libboost_filesystem.so

您的问题是由文件名后面的逗号 ('/usr/lib/x86_64-linux-gnu/libboost_filesystem.so,') 引起的。您应该删除 CMake 函数调用中的逗号分隔参数（只需在它们之间留一些空格）。
