背景是这样的:最近闲着报了个深圳人社的 c 语言培训班。 完了之后想要把之前自己写的 python 图片处理脚本用 C 写一遍。 然后就发现没法引用第三方库(也许是自己哪里做错了)。
以使用第三方库 fmt 为例,按照下述操作之后,在测试文件 test.c
里面输入 #include <f
vscode 能自动联想出#include <fmt/format.h>
,但是在 debug 或 run without debug 时终端会报错以下内容 :
#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (C:\Users\xxx\Desktop\C\test.c).
cannot open source file "cmath" (dependency of "C:\Users\xxx.vscode\extensions\ms-vscode.cpptools-1.20.5-win32-x64\bin\fmt\format.h"). Please run the 'Select IntelliSense Configuration...' command to locate your system headers.
fmt/format.h: No such file or directory
gcc/gdb 都已经正常安装并且可以在终端正常使用; 其中,gcc 路径为:C:\MinGW\bin\gcc.exe ; gdb 版本为 GNU gdb (GDB) 7.6.1 ;
包管理用的是 vcpkg; 安装到包的路径是:C:\vcpkg\installed\x64-windows\include
vscode 装了插件:C/C++ v1.20.5
在 google 操作之后下来,之后相关文件内容如下:

#include <fmt/format.h>
int main(void){
int a = 1;
fmt::print("a is {}", a);
return 0;
