我正在尝试使用c ++和Qt与通过GPIB连接到Windows PC的Yokogawa GS200 DC信号源进行通信。
我从横河电机（https://y-link.yokogawa.com/YL008.po?V_ope_type=Show&Download_id=DL00002096&Language_id=EN）找到了一个应该完成任务的图书馆;但是，当我尝试运行一个简单的代码时，它编译时没有错误，但没有输出或任何符号表示函数已执行。我会得到“按＆lt; ENTER＆gt;退出此窗口”
我不确定究竟有什么问题，任何人都有任何想法？
代码和头文件如下：
主：
#include "tmctl.h"
int main()
{
char adr[100];
int ret;
int id;
char buf[1000];
int length;
ret = TmcInitialize( TM_CTL_GPIB, "11", &id );
if( ret != 0 ) {
return TmcGetLastError( id );
}
ret = TmcSetTerm( id, 3, 1 );
if( ret != 0 ) {
return TmcGetLastError( id );
}
ret = TmcSetTimeout( id, 300 );
if( ret != 0 ) {
return TmcGetLastError( id );
}
ret = TmcSetRen( id, 1 );
if( ret != 0 ) {
return TmcGetLastError( id );
}
/* sending *RST */
ret = TmcSend( id, "*RST" );
if( ret != 0 ) {
return TmcGetLastError( id );
}
/* *sending IDN? & receiving query */
ret = TmcSend( id, "*IDN?" );
if( ret != 0 ) {
return TmcGetLastError( id );
}
ret = TmcReceive( id, buf, 1000, &length );
if( ret != 0 ) {
return TmcGetLastError( id );
}
}

除了.dll文件之外，还可以在库文件夹here中找到对函数和变量的描述。
当然我使用LIBS += "...\tmctl.dll"将库链接到我的项目。
答案 0 :(得分：0)
唯一的区别是我尝试使用VS运行代码，为此我将dll文件添加到（C \ windows \ system）目录。在它工作之后，我想在Qt中再试一次，并且意外地工作了！
虽然我怀疑系统目录中的dll文件是否有任何影响，因为当我将其包含在Qt中时，我引用了另一个位置。
如果有人有任何见解或理论，请随时分享。
