用i 686-w64-mingw32-g++编译Chaiscript失败

Question

我正在尝试使用i 686-W64-mingw32-g++编译器为Linux窗口编译一个简单的chaiscript示例。我已经让它与g++一起工作，但是当使用命令编译我的应用程序时

i686-w64-mingw32-g++ ./main.cpp -pthread -L/lib/x86_64-linux-gnu/libdl.a -std=c++17

以下是main.cpp的内容

#include "chaiscript/chaiscript.hpp"
#include "chaiscript/chaiscript_stdlib.hpp"

int main()
{
  chaiscript::ChaiScript chai;

  chai.eval(R"(puts("Hello"))");
}

这就是它给我的错误

如何修复此错误，以便编译代码？

编辑：

通过使用x86_64-w64-mingw32-g++而不是i 686-W64-mingw32-g++，我能够取得更好的进展，但现在我得到了以下错误：

/usr/bin/x86_64-w64-mingw32-as: /tmp/ccE1ZcKe.o: too many sections (73147)
/tmp/ccwlaMBb.s: Assembler messages:

/usr/bin/x86_64-w64-mingw32-as: /tmp/ccE1ZcKe.o: too many sections (73147)

Answer 1

下面是使用cmake的解决方案：

首先创建一个工具链文件：

# the name of the target operating system
set(CMAKE_SYSTEM_NAME Windows)

 

# which compilers to use
set(CMAKE_C_COMPILER x86_64-w64-mingw32-g++)
set(CMAKE_CXX_COMPILER x86_64-w64-mingw32-g++)

set(CMAKE_FIND_ROOT_PATH /usr/x86_64-w64-mingw32)


# adjust the default behavior of the find commands:
# search headers and libraries in the target environment
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)

 

# search programs in the host environment
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)

​

下一步是使实际的CMakeLists.txt：

# set minimum cmake version
cmake_minimum_required(VERSION 3.5 FATAL_ERROR)

# project name and language
project(HelloWorld LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_EXTENSIONS OFF)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

 

include(GNUInstallDirs)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/${CMAKE_INSTALL_LIBDIR})
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/${CMAKE_INSTALL_LIBDIR})
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/${CMAKE_INSTALL_BINDIR})

# define executable and its source file
add_executable(HelloWorld main.cpp)

if("${CMAKE_SYSTEM_NAME}" STREQUAL "Windows")
  add_definitions(-O3)
  SET(CMAKE_CXX_FLAGS  "-pthread -Wa,-mbig-obj -static -std=c++17")
  target_link_libraries(HelloWorld PUBLIC "-L/lib/x86_64-linux-gnu/libdl.a")
endif()

​

之后，运行以下命令来生成：

mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=../toolchainfile.cmake
cmake --build .

​

现在您应该有一个可工作的exe文件，用于chaiscript。

看来你首先需要#include <mutex>。也许你也需要别人。
