[解决]VSCode在Linux下导入c语言头文件警告

2023-04-18 06:00| 来源: 网络整理| 查看: 265

VSCode导入#include 文件时提示以下错误：

#include errors detected. Please update your includePath. IntelliSense features for this translation unit (/wk/c01/main.c) will be provided by the Tag Parser.cannot open source file "stddef.h" (dependency of "stdio.h")

这是由于配置中没有指定依赖路径导致的，在c_cpp_properties.json中includePath的默认配置只有当前目录，需要将系统依赖加入。

在命令行里面输入gcc -v -E -x c++ -在结果里面找到头文件目录,然后添加到includepath中。

运行结果如下:

使用内建 specs。 COLLECT_GCC=gcc OFFLOAD_TARGET_NAMES=nvptx-none OFFLOAD_TARGET_DEFAULT=1 目标：x86_64-redhat-linux 配置为：../configure --enable-bootstrap --enable-languages=c,c++,objc,obj-c++,fortran,ada,go,lto --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-shared --enable-threads=posix --enable-checking=release --enable-multilib --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-gcc-major-version-only --with-linker-hash-style=gnu --enable-plugin --enable-initfini-array --with-isl --enable-libmpx --enable-offload-targets=nvptx-none --without-cuda-driver --enable-gnu-indirect-function --with-tune=generic --with-arch_32=i686 --build=x86_64-redhat-linux 线程模型：posix gcc 版本 7.3.1 20180130 (Red Hat 7.3.1-2) (GCC) COLLECT_GCC_OPTIONS='-v' '-E' '-mtune=generic' '-march=x86-64' /usr/libexec/gcc/x86_64-redhat-linux/7/cc1plus -E -quiet -v -D_GNU_SOURCE - -mtune=generic -march=x86-64 忽略不存在的目录“/usr/lib/gcc/x86_64-redhat-linux/7/include-fixed” 忽略不存在的目录“/usr/lib/gcc/x86_64-redhat-linux/7/../../../../x86_64-redhat-linux/include” #include "..." 搜索从这里开始： #include 搜索从这里开始： /usr/lib/gcc/x86_64-redhat-linux/7/../../../../include/c++/7 /usr/lib/gcc/x86_64-redhat-linux/7/../../../../include/c++/7/x86_64-redhat-linux /usr/lib/gcc/x86_64-redhat-linux/7/../../../../include/c++/7/backward /usr/lib/gcc/x86_64-redhat-linux/7/include /usr/local/include /usr/include 搜索列表结束。

将以下路径添加到includePath中

/usr/lib/gcc/x86_64-redhat-linux/7/../../../../include/c++/7 /usr/lib/gcc/x86_64-redhat-linux/7/../../../../include/c++/7/x86_64-redhat-linux /usr/lib/gcc/x86_64-redhat-linux/7/../../../../include/c++/7/backward /usr/lib/gcc/x86_64-redhat-linux/7/include /usr/local/include /usr/include

配置好的c_cpp_properties.json如下:

{ "configurations": [{ "name": "Linux", "includePath": [ "${workspaceFolder}/**", "/usr/lib/gcc/x86_64-redhat-linux/7/../../../../include/c++/7", "/usr/lib/gcc/x86_64-redhat-linux/7/../../../../include/c++/7/x86_64-redhat-linux", "/usr/lib/gcc/x86_64-redhat-linux/7/../../../../include/c++/7/backward", "/usr/lib/gcc/x86_64-redhat-linux/7/include", "/usr/local/include", "/usr/include" ], "defines": [], "compilerPath": "/usr/bin/clang", "cStandard": "c11", "cppStandard": "c++17", "intelliSenseMode": "clang-x64" }], "version": 4 }
