windows上怎麼用libnfc的庫函數程式設計

根據libnfc的說明文檔，我在win7上裝了

libnfc-1.7.0-rc6.Zip 

MinGW64

libusb-win32-bin-1.2.6.0

CMake -2.8.10-win32-x86 

然後用mingw32-make指令編譯成功，并産生了libnfc.dll檔案，并且能夠順利運作nfc-list.exe等例子。

但是我想問一下，如果我想自己寫一個.c檔案，我該如何調用libnfc的頭檔案庫和函數庫編譯它呢？

//test.cpp

#include <iostream>

#include "libnfc_read_only\include\nfc\nfc.h"

using namespace std;

int main() {

    cout << nfc_version() << "\n";

    return 0;

}

我用 gcc -o test test.cpp -lnfc 指令編譯，會報錯說找不到頭檔案。我将之前編譯成功的libnfc.dll檔案放在同一目錄下，仍然報錯。

求指導:-)

I got it!

Thanks a lot for yobibe's help. I finally compiled it successfully, the steps are as follow:

Before that, I'll describe my files and directories:

The operating system is windows 7-32bit.

E:.

├─libnfc-1.7.0-rc6

│  ├─cmake

│  ├─contrib

│  ├─examples

│  ├─include

│  ├─libnfc

│  ├─libusb

│  ├─m4

│  ├─test

│  └─utils

│      ├─nfc-list.c

│      ├─CmakeList.txt

│      └─test.c

│

└─nfc_built

     ├─utils

     │  ├─nfc-list.exe

     │  └─libnfc.dll

     ├─libnfc

     │  └─libnfc.dll

     │

     └─(and so on)

when the operation "Cmake-->mingw32-make" achieved, copy the E:\nfc_built\libnfc\libnfc.dll to E:\nfc_built\utils, and then open the cmd.exe window:

C:\Users\WangYong> cd :e\libnfc\nfc_built\utils

e\libnfc\nfc_built\utils> nfc-list.exe

nfc-list.exe will run and then print the result.

If you write a program by yourself, for example:

//test.c

#include <stdio.h>

#include <nfc\nfc.h>

int main()

{

    printf("%s",nfc_version());

    return 0;

}

Next you should put the test.c in the E:\libnfc\libnfc-1.7.0-rc5\utils, and modify the CmakeList.txt which is under the same directory(E:\libnfc\libnfc-1.7.0-rc5\utils) by adding the "test" to CmakeList.txt:

SET(UTILS-SOURCES 

  nfc-emulate-forum-tag4

  nfc-list

  nfc-mfclassic

  nfc-mfultralight

  nfc-read-forum-tag3

  nfc-relay-picc

  nfc-scan-device

  test

)

Finally, do the mingw32make again, and then you will see the test.exe under E:\libnfc\nfc_built\utils. Run it:

E:\libnfc\nfc_built\utils> test.exe

ok! The version of libnfc will be printed on the cmd screen. You can also compile and run the quick_start_example1.c by this way. Good luck!
