未定义的CyAPI函数引用

我将Qt项目中的静态库CyAPILIB与.Pro文件中的下列行链接起来：
代码& gt；lbs+$ldpd//lpgt/gayskullMt/Cypress /-lCyAPI包含$PdD/ION/SPAMT/GraySkullMt/CyPress依赖路径+= $$PDW/ION/SPAMT/GraySkullMt/CyPress PrimeToeDePSP+= $$PDW/ION/SPAMT/GraySkullMt/CyPress／CyAPI.LIB& Lt/／Clult& Gt；
……我在新类的源文件中包含了CyAP.h头文件（在同一个目录中与其他相关的头，CysB30G.DEF.H等），并尝试使用几个函数，如下所示：
代码& gt；包括：SPAMT/GraySkullMt/CyPress／CyAPI。gsDeals=新的cCysBeDebug（）；如果（gStand -gt；DeVeCeCuffTo）（0）{GsDealth＆Gt；OPEN（0）；}…CCYSUBESTPONT *EP= GSS-设备& EndPointOf；（0x03）；
……但是每次尝试使用CyAPI提供的任何函数时，都会得到一个“未定义的引用&函数；gt；”错误。这使我认为静态库没有被链接，因为我假设这是定义所有函数的地方。但是，在读取.pro文件或与库链接相关的任何编译时错误时，我不会看到QQuess错误。这里发生了什么事？为什么我会得到这些未定义的参考错误？请帮助！
作为一个侧重点，我必须将''`````````````````.l>；Windows & h & gt；']包含到CysB30.DEF.h中，以获得编译器所识别的各种uCHAR、uINT等关键字。我觉得很奇怪，这被排除在外，所以我可能在这里打破一些东西。
谢谢，

     以下为原文
  I'm linking the static library CyAPI.lib in a Qt project with the following lines in the .pro file:
   
unix|win32: LIBS += -L$$PWD/include/SpaMt/GrayskullMt/Cypress/ -lCyAPI
INCLUDEPATH += $$PWD/include/SpaMt/GrayskullMt/Cypress
DEPENDPATH += $$PWD/include/SpaMt/GrayskullMt/Cypress
PRE_TARGETDEPS += $$PWD/include/SpaMt/GrayskullMt/Cypress/CyAPI.lib

    ...and I've included the CyAPI.h header file (in the same directory with the other related headers, CyUSB30_def.h, etc) in the source file of a new class and attempted to use several functions, like this:
   
#include
...
gsDevice = new CCyUSBDevice();
...
if(gsDevice->DeviceCount() > 0)
{
    gsDevice->Open(0);
}
...
CCyUSBEndPoint *ep = gsDevice->EndPointOf(0x03);

    ...but I get an "Undefined reference to " error each time I attempt to use any of the functions provided by CyAPI. This makes me think that the static library is not being linked, as I assume that's where all the functions are defined. However I don't see any qmake errors when it reads the .pro file or any compile-time errors related to the linking of the library. What's going on here? Why am I getting these undefined reference errors? Please help!
    As a side note, I had to include '#include ' to CyUSB30_def.h to have the various UCHAR, UINT, etc keywords recognized by the compiler. I thought it was strange this was left out, so maybe I'm breaking something here.
    Thanks,
    Forrest
