Undefined reference to `DAQmxCreateTask@8 not able to link DLL VS codes-CodePudding

Im using VS codes to build a C program, i need to use a third party DLL from National instruments I have included the .h file in my program "NIDAQmx.h", but still when i run the program, the functions in this DLL is undefined How can i link this DLL to my code?

my code goes like this

#include<stdio.h>
#include"C:\Program Files (x86)\National Instruments\Shared\ExternalCompilerSupport\C\include\NIDAQmx.h"

TaskHandle taskHandle=0;
int ret=0;

    void main()
{
    printf("Hello world");
    ret=DAQmxCreateTask("task",&taskHandle);
    printf("Return for creating task is %d\n",ret);
    DAQmxStopTask (taskHandle);
    DAQmxClearTask(taskHandle);
    printf("Task closed ");

}`

this is my console output

[Running] cd "d:\VSCODES\" && gcc test.c -o test && "d:\VSCODES      \"test C:\Users\rahul\AppData\Local\Temp\ccuN1dmO.o:test.c:(.text 0x32):       

undefined reference to `DAQmxCreateTask@8'

C:\Users\rahul\AppData\Local\Temp\ccuN1dmO.o:test.c:(.text 0x5c):        undefined reference to `DAQmxStopTask@4'

C:\Users\rahul\AppData\Local\Temp\ccuN1dmO.o:test.c:(.text 0x6c): undefined reference to `DAQmxClearTask@4'

collect2.exe: error: ld returned 1 exit status

[Done] exited with code=1 in 0.244 seconds`

I tried giving path to the DLL like this

 PS D:\VSCODES> code --add "C:\Program Files (x86)\National        Instruments\Shared\ExternalCompilerSupport\C\lib32\msvc\NIDAQmx.lib"

but its giving error

as suggested by one forum, i tried editing my tasks.json file

 {
"tasks": [
    {
        "type": "cppbuild",
        "label": "C/C  : gcc.exe build active file",
        "command": "C:\\MinGW\\bin\\gcc.exe",
        "args": [
            "-fdiagnostics-color=always",
            "-g",
            "${file}",
            "-o",
            "${fileDirname}\\${fileBasenameNoExtension}.exe"
            "-LC:\\"C:\Program Files (x86)\National Instruments\Shared\ExternalCompilerSupport\C\lib32\msvc\NIDAQmx.lib"
            "-lNIDAQmx.lib",
        ],
        "options": {
            "cwd": "${fileDirname}"
        },
        "problemMatcher": [
            "$gcc"
        ],
        "group": {
            "kind": "build",
            "isDefault": true
        },
        "detail": "Task generated by Debugger."
    }
],
"version": "2.0.0"
}

but this also didn't help

as suggested by answer i tried giving build in VS code terminal

but it returned error

PS D:\VSCODES> gcc test.c -o test -L"C:\Program Files (x86)\National    Instruments\Shared\ExternalCompilerSupport\C\lib32\msvc" -lNIDAQmx.lib

gcc.exe: error: .lib: No such file or directory

I also changed the Task.json file, but still same error

CodePudding user response：

You can try specifying the library path in the command line you use to build the project:

gcc test.c -o test -L"C:\Program Files (x86)\National Instruments\Shared\ExternalCompilerSupport\C\lib32\msvc" -lNIDAQmx.lib

Also your tasks.json file is not well-formed. Could you please try this:

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C  : gcc.exe build active file",
            "command": "C:\\MinGW\\bin\\gcc.exe",
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe",
                "-LC:\\Program Files (x86)\\National Instruments\\Shared\\ExternalCompilerSupport\\C\\lib32\\msvc\\NIDAQmx.lib",
                "-lNIDAQmx.lib"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "Task generated by Debugger."
        }
    ],
    "version": "2.0.0"
}

Here is your original tasks.json file with additional parameters:

{
    "tasks": [
        {
            "type": "shell",
            "label": "C/C  : gcc.exe build active file",
            "command": "C:\\MinGW\\bin\\gcc.exe",
            "args": [
                "-g",
                "test.c",
                "-o",
                "test.exe",
                "-LC:\\Program Files (x86)\\National Instruments\\Shared\\ExternalCompilerSupport\\C\\lib32\\msvc\\NIDAQmx.lib",
                "-lNIDAQmx.lib"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "Task generated by Debugger."
        }
    ],
    "version": "2.0.0"
}
