尝试在CLion / CMake中构建共享库 [英] Trying to build shared library in CLion/CMake

问题描述

我一直在尝试下载并构建

如果我告诉它无论如何都会生成以下错误。 / p>

我一直在努力寻找答案为什么我需要一个可执行文件来构建库以及那些未定义的引用的含义。

解决方案

我不知道这是否是原因问题，但include命令应如下所示： include_directories（$ {MyHeaders}）。 $ {MyHeaders} 将扩展变量 MyHeaders 并将其当前值传递给 include_directories 。否则，从字面上看，您将包括目录 MyHeaders 。

I've been trying to download and build the Stanford Library source files and build a library out of them to use for my own project using the CLion (IDE). I've been following instructions from this answer and my CMakeLists file looks like this:

cmake_minimum_required(VERSION 3.3)
project(Stanford)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(CMAKE_BUILD_TYPE Release)


file(GLOB MyHeaders "*.h" /stacktrace/"*.h" private/"*.h")
file(GLOB MySources "*.cpp" /stacktrace/"*.cpp" private/"*.cpp")
include_directories(MyHeaders)
add_library(Stanford SHARED ${MySources} ${MyHeaders})


target_include_directories (Stanford PUBLIC ${CMAKE_CURRENT_SOURCE_DIR})

When opening the run menu, I get the following:

If I tell it to build anyway I get the following errors.

I've been struggling to find out what why I need an executable to build a library and what those undefined references mean.

解决方案

I don't know if it's the cause of your problem, but include command should look like this: include_directories(${MyHeaders}). ${MyHeaders} will expand the variable MyHeaders and pass its current value to include_directories. Otherwise you are, literally, including directory MyHeaders.
