Windows系统下开发环境研究

时隔多年重新参与windows系统下的软件开发工作，现记录一下在windows下的c++开发环境搭建。

1. code

C/C++ extension tutorials per compiler and platform

• Microsoft C++ compiler (MSVC) on Windows 使用Microsoft C++编译器方案
• GCC and Mingw-w64 on Windows 使用gcc或clang编译器方案
• GCC on Windows Subsystem for Linux (WSL) 使用WSL子系统开发Linux程序的方案
• GCC on Linux
• Clang on macOS

2. gcc编译mfc程序

//main.cpp
 
#include <windows.h>
 
#pragma comment(lib,"user32.lib")
 
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
	MessageBox(NULL,"This is a test!","Title",MB_OKCANCEL);
	return 0;
}

$ g++ main.cpp -o obj

问题1:

GCC编译的会弹出一个黑框框，然后再弹出对话框窗体，而cl编译的可执行程序不会弹出黑框框，直接就弹出一个对话框窗体。

解决:

ld 对应命令是 --subsystem=windows

shell

$ g++ main.cpp -o obj -mwindows

make

LDFLAGS=-mwindows

cmake

# project(${PACKAGE_NAME})
# C项目中
# error LNK2001: 无法解析的外部符号 WinMainCRTStartup
project(${PACKAGE_NAME} LANGUAGES C)

if(CMAKE_SYSTEM_NAME MATCHES "Windows")
  add_executable(${PACKAGE_NAME} WIN32 ${DIR_SRCS})

  if(CMAKE_BUILD_TYPE STREQUAL "release")
    set_target_properties(${PACKAGE_NAME} PROPERTIES LINK_FLAGS_RELEASE "/SUBSYSTEM:WINDOWS /ENTRY:mainCRTStartup")
  else()
    set_target_properties(${PROJECT_NAME} PROPERTIES LINK_FLAGS_DEBUG "/SUBSYSTEM:WINDOWS /ENTRY:mainCRTStartup")
  endif()
else()
  add_executable(${PACKAGE_NAME} ${DIR_SRCS})

  if(CMAKE_BUILD_TYPE STREQUAL "release")
    set_target_properties(${PACKAGE_NAME} PROPERTIES LINK_FLAGS_RELEASE -s)
  endif()
endif()

# error LNK2019: 无法解析的外部符号 WinMain
# 用 /SUBSYSTEM:CONSOLE 替换 /SUBSYSTEM:WINDOWS 并去掉 WIN32

add_executable(${PACKAGE_NAME} ${DIR_SRCS})

if(CMAKE_SYSTEM_NAME MATCHES "Windows")
  if(CMAKE_BUILD_TYPE STREQUAL "release")
    set_target_properties(${PACKAGE_NAME} PROPERTIES LINK_FLAGS_RELEASE "/SUBSYSTEM:CONSOLE /ENTRY:mainCRTStartup")
  else()
    set_target_properties(${PROJECT_NAME} PROPERTIES LINK_FLAGS_DEBUG "/SUBSYSTEM:CONSOLE /ENTRY:mainCRTStartup")
  endif()
else()
  if(CMAKE_BUILD_TYPE STREQUAL "release")
    set_target_properties(${PACKAGE_NAME} PROPERTIES LINK_FLAGS_RELEASE -s)
  endif()
endif()

c/c++

#ifdef WIN32
#  include <windows.h>
#  pragma comment( linker, "/subsystem:\"windows\" /entry:\"mainCRTStartup\"" )
#endif
