我有一個鏈接問題,當我試圖從boost使用文件系統。我複製代碼教程:鏈接錯誤使用boost庫和clion
#include <iostream>
#include <boost/filesystem.hpp>
using namespace boost::filesystem;
int main(int argc, char* argv[])
{
if (argc < 2)
{
std::cout << "Usage: tut1 path\n";
return 1;
}
std::cout << argv[1] << " " << file_size(argv[1]) << '\n';
return 0;
}
或許它應該工作,但我有這樣的錯誤:
Scanning dependencies of target untitled

我的CMakeLists.txt文件:
cmake_minimum_required(VERSION 3.7)
project(untitled)
set(CMAKE_CXX_STANDARD 11)
set(SOURCE_FILES main.cpp)
add_executable(untitled ${SOURCE_FILES})
find_package(Boost)
IF (Boost_FOUND)
include_directories(${Boost_INCLUDE_DIR})
endif()
我能提高什麼編譯這個代碼?我在OSX上使用CLion編輯器。
請向我們展示您的make make/makefile/CMakeLists.txt! – Rama
'cmake_minimum_required(3.7版) 項目(無) 集(CMAKE_CXX_STANDARD 11) 集(SOURCE_FILES main.cpp中) add_executable(無$ {} SOURCE_FILES) find_package(升壓) IF(Boost_FOUND) include_directories ($ {Boost_INCLUDE_DIR}) endif()' 對不起,這種粘貼格式 - 我不知道如何使它成爲多行。 – emil
@emil你將要把它附加到你的問題,而不是留在評論中。 – chbchb55
