Question

抱歉我的英文。

我尝试将iperf3（如静态链接库）添加到我的Qt项目（Qt版本4.8.5，OpenSuse 13.1），并有几个错误：

当我尝试将iperf3添加到唯一的C ++项目时，一切都很好。此错误仅存在于Qt项目中。有什么想法吗？

Answer 1

我对iperf3和Qt也有同样的问题。基本上你似乎必须为iperf3库和你的项目（gcc或g ++）使用类似的编译。

让我们知道它是怎么回事。如果已经完成，请分享您的解决方案。

- 编辑 - 或者为iperf_api.h执行以下操作

extern "C" {
#include <iperf_api.h>
}

Qt + iperf3 = lconv尚未申报
