Error when declaring QStringList

I have a public function:

void determineAction(QStringList tempL); // in header file

void CompArch::determineAction(QStringList tempL)
{


}

//in cpp file

I get the error:

CompArch.cpp:127:6: error: ‘tempL’ has incomplete type
/usr/include/qt4/QtCore/qstring.h:77:7: error: forward declaration of ‘struct QStringList’

any ideas why this might be.

add #include <QStringList> to the top of your .cpp file. Incomplete type means that your class (QStringList) has already been named before, using foward declaration, but the content of it has not been declared.

Incomplete type means that the compiler has seen QStringList as class, but did not see the body of the QStringList class header. It looks like you must include a header that does contain the class header body for QStringList.
