如何让ChaiScript在Linux和CMake操作系统下运行？

Question

我正在做一个学生项目，我们希望使用ChaiSript (6.1)作为脚本语言。我们在Linux和Windows上使用CLion和CMake。另外，我们使用的是SFML，所以在Windows7.3.0环境下必须使用minGW 7.3.0进行编译。

我在Linux下创建了一个测试项目(gcc 9.2.0和c++ 17)，并得到了以下链接器错误：

/usr/bin/ld: CMakeFiles/ChaiScriptTest.dir/main.cpp.o: in function `chaiscript::detail::Loadable_Module::DLModule::DLModule(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)':

所有错误都是由于chaisript_posix.hpp和chaiscript_engine.hpp中缺少对dlfcn.h中函数的引用所致。除了最后一个线程类有问题。

那我该怎么解决这个问题？Linux上的编译器与此无关，但必须使用MinGW 7.3.0。

我已经尝试过的是：

• 使用c++14代替c++17
• 使用Chaiscript Version 6.0和5.8.3wtih，而非c++14
• 使用在6.1和5.8.3上编译的没有CMake的clang
• 和-ld选项集(也有和不带c++17)

这是我的CMakeLists.txt：

cmake_minimum_required(VERSION 3.15)
project(ChaiScriptTest)

set(CMAKE_CXX_STANDARD 17)

include_directories(ChaiScript-6.1.0/include)


add_executable(ChaiScriptTest main.cpp)

我的main.cpp文件：

#include <iostream>
#include "chaiscript/chaiscript.hpp"

int main() {
    chaiscript::ChaiScript chaiScript_;

    chaiScript_.eval("print(\"Hi\");");

    std::cout << "Hello ChaiScript" << std::endl;

    return 0;
}

提前谢谢。

不过，我自己解决了问题..。

我查看了文档，发现Jason已经了解到了这一点。

chai.add(chaiscript::fun(std::bind(&MacroEngine::setIgnoredMod, me, std::placeholders::_1)), "setIgnoredMods");

如果将同一行更改为

chai.add(chaiscript::fun(&MacroEngine::setIgnoredMod, &me), "setIgnoredMod");
