文章目录问题includesourceout配置过程遇到的问题与解决遇到的问题1解决步骤1. ctrl shift p2. 配置json文件修改task.json文件修改launch.json可能遇到的错误1. collect2: error: ld returned 1 exit status2. /mnt/d/tmp/c/source/add.cpp:3:10: fatal error: add.h: No such file or directoryc_cpp_properties.json问题
如下图文件夹 include: *.h文件out: 编译后的输出文件夹source*.cpp文件先看看我们的几个文件夹里有什么文件还有文件里有什么内容。
include
add.h 这里就是add()函数的声明还需要要加上 int test_add();这个声明
source
main.cpp 简单的一个程序入口 add.cpp 这里是我们主要的程序部分定义了几个add()函数。还有test_add()函数还需要#include “add.h”
out
现在还没有编译过所以为空
那我们要怎样配置vscode里的一些环境呢
配置过程遇到的问题与解决
遇到的问题1
identifier test_add is undefinedC/C(20)说白了就是test_add这个标识符不能识别没有定义可我们从上面的文件里看到了该函数都是有的。再往下看我们一个一个来解决。
解决步骤
1. ctrl shift p
然后选择如下箭头所指示
出现如下选择Debug Anyway 完成这一步了我们可以参文件下面会有一个.vscode的文件夹还有两个.json的文件。
2. 配置json文件
修改task.json文件
默认的如下主要要修改三个地方
添加 -I及-I对应的文件夹 (include)修改 -o及-o对文件夹 (out)修改-g及-g对应的文件(source)
{tasks: [{type: cppbuild,label: C/C: g build active file,command: /usr/bin/g,args: [-g,${file},-o,${fileDirname}/${fileBasenameNoExtension}],options: {cwd: ${fileDirname}},problemMatcher: [$gcc],group: {kind: build,isDefault: true},detail: Task generated by Debugger.}],version: 2.0.0
}修改如下
{tasks: [{type: cppbuild,label: C/C: g build active file,command: /usr/bin/g,args: [-g,${workspaceFolder}/source/*.cpp, //all cpp from source-I, //include${workspaceFolder}/include, //include path-o,${workspaceFolder}/out/${fileBasenameNoExtension} //out path],options: {cwd: ${fileDirname}},problemMatcher: [$gcc],group: {kind: build,isDefault: true},detail: Task generated by Debugger.}],version: 2.0.0
}修改launch.json
默认的launch.json如下 只需要修改2版主即可
“program” 后的属性修改成与tasks.json -o 后的属性一样“cwd”: 属性修改为 “${workspaceFolder}/out”

}修改如下都已经加注释了
{// Use IntelliSense to learn about possible attributes.// Hover to view descriptions of existing attributes.// For more information, visit: https://go.microsoft.com/fwlink/?linkid830387version: 0.2.0,configurations: [{name: g - Build and debug active file,type: cppdbg,request: launch,program: ${workspaceFolder}/out/${fileBasenameNoExtension}, //program output name, same as tasks.json -o pathargs: [],stopAtEntry: false,cwd: ${workspaceFolder}/out, //out here is the folder named outenvironment: [],externalConsole: false,MIMode: gdb,setupCommands: [{description: Enable pretty-printing for gdb,text: -enable-pretty-printing,ignoreFailures: true}],preLaunchTask: C/C: g build active file,miDebuggerPath: /usr/bin/gdb}]
}保存以上文件后已经不报错了
F5: 调试程序CTRLF5运行程序ctrl shift B (build) 可能遇到的错误
1. collect2: error: ld returned 1 exit status
/usr/bin/g -g /mnt/d/tmp/c/source/main.cpp -I /mnt/d/tmp/c/include -o /mnt/d/tmp/c/out/main
/tmp/ccBwxewk.o: In function main:
/mnt/d/tmp/c/source/main.cpp:8: undefined reference to test_add()
collect2: error: ld returned 1 exit statustasks.json -g 后面的参数改为 “${workspaceFolder}/source/*.cpp”
2. /mnt/d/tmp/c/source/add.cpp:3:10: fatal error: add.h: No such file or directory
Starting build...
/usr/bin/g -g /mnt/d/tmp/c/source/*.cpp -o /mnt/d/tmp/c/out/main
/mnt/d/tmp/c/source/add.cpp:3:10: fatal error: add.h: No such file or directory#include add.h^~~~~~~
compilation terminated.
/mnt/d/tmp/c/source/main.cpp:2:10: fatal error: add.h: No such file or directory#include add.h^~~~~~~
compilation terminated.Build finished with error(s).
The terminal process failed to launch (exit code: -1).tasks.json 加上-I, “${workspaceFolder}/include”,
c_cpp_properties.json
c_cpp_properties.json配置文件默认是不会产生的ctrlshiftp 再输入configuration选择后便会出现。
在这里我们可以设置 includePath
{configurations: [{name: Linux,includePath: [${workspaceFolder}/**,${workspaceFolder}/include/** //your include path],defines: [],compilerPath: /usr/bin/gcc,cStandard: gnu11,cppStandard: gnu14,intelliSenseMode: linux-gcc-x64}],version: 4
}注请注意这里使用是的WSL环境下的g。
