Qt：嘗試在qt中使用python.h時未定義的符號

Question

我在Mac上用Qt做了一些小小的工作。我需要在我的主函數中調用一個python函數。但是，當我嘗試調用Py_initialize（）爲大家都說，編譯器將拋出一個錯誤這樣的：

Undefined symbols for architecture x86_64: 
    "_Py_Initialize", referenced from: 
    _main in main.o 
ld: symbol(s) not found for architecture x86_64 
clang: error: linker command failed with exit code 1 (use -v to see 
invocation) 
make: *** [video.app/Contents/MacOS/video] Error 1 
07:48:07: The process "/usr/bin/make" exited with code 2. 
Error while building/deploying project video (kit: Desktop Qt 5.8.0 
clang 64bit) 
When executing step "Make" 

我的代碼是微不足道，不應該有什麼奇怪的這一點。這是它：

// bunch of headers 
#include <python2.7/Python.h> 

using namespace std; 


int main(int argc, char *argv[]) 
{ 

Py_Initialize(); 

QGuiApplication app(argc, argv); 

QQmlApplicationEngine engine; 

QQmlComponent component(&engine, QUrl(QStringLiteral("qrc:///main.qml"))); 
QObject *object = component.create(); 
QObject *mainForm = object->findChild<QObject*>("mainForm"); 

SignalNexus sn; 

QObject::connect(mainForm, SIGNAL(populateToken(QString)), &sn, SLOT(pushToPipe(QString))); 

QObject::connect(&sn, SIGNAL(populateResult(QVariant, QVariant)), mainForm, SLOT(handleResult(QVariant, QVariant))); 
return app.exec(); 
} 

當我評論Py_initalize（）線，一切工作正常。我認爲這與OSx有關。但我真的不知道如何解決這個問題。需要幫助。

更改您的包括線這個

// bunch of headers 
#include <Python/Python.h> 

using namespace std; 


int main(int argc, char *argv[]) 
{ 

Py_Initialize();
