QT Creator添加Cypress提供的C++ LIB库

chris_renyi

Cypress公司提供的C++版本驱动接口是CyAPI.h等8个头文件和一个CyAPI.lib文件。

在主窗口类中添加包含：
#include "windows.h"#include "CyAPI.h"

在主窗口类的构造函数中添加代码：
    CCyUSBDevice *USBDevice=new CCyUSBDevice(NULL);    int eptCount = USBDevice->EndPointCount();    CCyControlEndPoint *ept = USBDevice->ControlEndPt;

通过在QT Creator项目上右击，添加静态库，只选择windows，没有debug，则pro文件里多出了如下的代码：
win32: LIBS += -L$$PWD/CyAPI/ -lCyAPIINCLUDEPATH += $$PWD/CyAPIDEPENDPATH += $$PWD/CyAPI
win32:!win32-g++: PRE_TARGETDEPS += $$PWD/CyAPI/CyAPI.libelse:win32-g++: PRE_TARGETDEPS += $$PWD/CyAPI/libCyAPI.a
直接run，结果又错误停止了mingw32-make[1]: *** No rule to make target 'D:/bs/13_qtAcqClient/qtAcqClient/CyAPI/libCyAPI.a', needed by 'debug\qtAcqClient.exe'.  Stop.
然后我把 Win32-g++去了，pro文件里的内容修改为win32: LIBS += -L$$PWD/CyAPI/ -lCyAPIINCLUDEPATH += $$PWD/CyAPIDEPENDPATH += $$PWD/CyAPIwin32: PRE_TARGETDEPS += $$PWD/CyAPI/CyAPI.lib
直接run只有，提示需要CyAPI.cpp:D:\bs\13_qtAcqClient\qtAcqClient\CyAPI\CyAPI.a(CyAPI.o):CyAPI.cpp.text+0xbcd): undefined reference to `_imp__SetupDiGetClassDevsA@16'

我已经添加库了，为什么还要我的cpp文件，这里没有cpp文件啊

遇到跟你差不多的问题，楼主解决没有呢？

楼主排版太乱了，这种错误是链接器报错
检查一下路径问题和.lib和.h文件

还有最好使用同一编译链

楼主问题解决了吗，我也遇到这个问题了
