我试图在VSCode中调试一个C++程序,使用microsoft/vscode-cmake-tools扩展,但在构建步骤中出现错误。

复制步骤:

1.克隆一个库,我需要在项目目录上使用. git submodule add https://github.com/dacap/clip.git clip,假设是C:\pg\cpp_dev_02
1.创建CMakeLists.txt(下面的内容),如Home · dacap/clip Wiki(下面的cmake配置输出日志)中所述
1.单击CMake菜单上的debug以尝试开始调试
1.失败并出现错误(下面的cmake构建输出日志/下面的屏幕截图)
这就是我的问题所在。
顺便说一下,在VSCode之外使用cmake进行构建是通过的。

cd C:\pg\cpp_dev_03\; mkdir build; cd build;
cmake ..
cmake --build . --config Release
C:\pg\cpp_dev_03\build\Release\myproject.exe
echo $? # True

字符串
以防万一版本:

> g++ --version
g++.exe (x86_64-posix-seh, Built by strawberryperl.com project) 8.3.0

我不知道出了什么事。谢谢你的帮助。谢谢。

  • CMakeLists.txt
cmake_minimum_required(VERSION 3.27)
project(myproject)

# Disable clip examples and tests
set(CLIP_EXAMPLES OFF CACHE BOOL "Compile clip examples")
set(CLIP_TESTS OFF CACHE BOOL "Compile clip tests")

# In case that you have ${PNG_LIBRARY} set to support copy/paste images on Linux
#set(CLIP_X11_PNG_LIBRARY "${PNG_LIBRARY}")

# Add clip subdirectory to compile the library
add_subdirectory(clip)

add_executable(myproject tmp3.cpp)

target_link_libraries(myproject clip)

  • tmp3.cpp
#include "clip/clip.h"
#include <iostream>

int main()
{
  clip::set_text("Hello World");

  std::string value;
  clip::get_text(value);
  std::cout << value << "\n";
}

似乎是一个与CLSID_WICPngDecoder2CLSID_WICPngDecoder1定义有关的问题没有找到。通过这个GitHub issue-35链接告诉你可能正在使用旧版本的MinGW。
导航到clip/clip_win_wic.h:210:33文件和行,并检查是否可以转到CLSID_WICPngDecoder2CLSID_WICPngDecoder1的定义,如果不能,这意味着库所需的依赖关系,特别是在您的情况下windowscodecs库,没有正确设置。
