Ethercat系列（10）用QT实现SOEM主站

1. 首先将SOEM编译成静态Lib库

可以参考前面的博文

(83条消息) VS2017下编译SOEM(Simle Open EtherCAT Master)_soem vs_CoderIsArt的博客-CSDN博客

make_libsoem_lib.bat "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build" x86

2. 用QT创建控制台程序并导入静态库

工程文件如下，

QT -= guiCONFIG += c++11 console
CONFIG -= app_bundle# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGSDEFINES += HAVE_STRUCT_TIMESPEC  #to void timespec redefinition compain# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0SOURCES += \main.cpp# Default rules for deployment.

DEPENDPATH += $$PWD/wpcap/Include/pcap

3. 修改一些必要的头文件

工程中有些头文件，没有对在C++环境中编译作处理，需要作如下处理。

#ifdef _cplusplus

extern "C" {

#endif

#ifdef _cplusplus

}

#endif

4. 加入缺少的系统库

#pragma comment(lib,"libsoem.lib")

#pragma comment(lib,"Packet.lib")

#pragma comment(lib,"wpcap.lib")

#pragma comment(lib,"ws2_32.lib")

#pragma comment(lib,"winmm.lib")

5. 运行结果
