Linux例程运行

在mToken-GM3000\skf\samples\readme.txt中得知相关例程功能，接下来修改其main文件或makefile文件使其能够编译通过并运行

DevAuth --------------设备认证例程

直接make编译，显示报错

main.cpp:21:23: warning: ISO C++ forbids converting a string constant to ‘char*’ [-Wwrite-strings]
   21 |  char *dev_auth_key = "1234567812345678";

参考warning: ISO C++ forbids converting a string constant to ‘char*解决方法，将char *dev_auth_key改成char const *dev_auth_key即可

再次make后运行成功

Signature --- 签名验证例程

同样先make，不过报了三个错，vim查看后应该是直接用数字字符初始化的都会报错

main.cpp: In function ‘int main()’:
main.cpp:24:19: warning: ISO C++ forbids converting a string constant to ‘char*’ [-Wwrite-strings]
   24 |  char *pUserPin = "123456";
      |                   ^~~~~~~~
main.cpp:36:16: warning: ISO C++ forbids converting a string constant to ‘char*’ [-Wwrite-strings]
   36 |  char *pubid = "1234567812345678";
      |                ^~~~~~~~~~~~~~~~~~
main.cpp:38:19: warning: ISO C++ forbids converting a string constant to ‘char*’ [-Wwrite-strings]
   38 |  char *psrcdata = "1234567812345678";

再次利用更换char const的方式make，但报了错

make: *** [makefile:43：main.o] 错误 1

虽然刚刚的方式可以通过编译，但实际上是改变了数据类型

参考linux 环境下：warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings]，得知还可将char* p = "abc";替换成char* p = (char*)"abc";

更改后通过编译并返回1

EncryptData --------------数据加解密例程

和上文相同方式，添加`(char*)后即可

monitordev-------------监听设备

报makefile错误

/usr/bin/ld: main.o: undefined reference to symbol 'pthread_create@@GLIBC_2.2.5'
/usr/bin/ld: /lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make: *** [makefile:30：monitordev] 错误 1

根据王浩博同学的方法，原makefile中出现了两个LINKFLAGS变量，只要将其中一个重命名并加入图中最下面一行即可（图中为改为LINKFLAG）

运行后监听20000s后结束程序

我判断此处应该插入eKey，但不能识别USB

尝试用wsl运行程序，但会报段错误

设断点判断是在此函数处出错，但是未能解决

ulRslt = SKF_WaitForDevEvent(szDevName, &ulDevNameLen, &ulEvent);
