QtCreator and external libraries

[GiuseppeBonfa]

Hi,

I've developed a test application that makes use of psapi but when
I try to compile it, I obtain linking error like this

prova2.cpp:66: undefined reference to `EnumProcesses@12'

So emerged the necessity to add libpsapi.a how can be done this in Qt Creator,
if i need to do this manually what I've to do?

Thanks,
Giuseppe Bonfa'

Open the .pro file and add LIBS += libpsapi.a and rerun qmake.

Thanks, solved by changing makefile in that way

LIBS =  -L"c:\Qt\QtCreator\qt\lib" -lmingw32 -lqtmaind -lQtGuid4 -lQtCored4 [B]-lpsapi[/B]

LIBS =  -L"c:\Qt\QtCreator\qt\lib" -lmingw32 -lqtmaind -lQtGuid4 -lQtCored4 [B]-lpsapi[/B]

To copy to clipboard, switch view to plain text mode 

now the problem is that i need to convert a TCHAR into QString

TCHAR szProcessName[4096] = {0};
//other code
QString  aaa = QString::fromUtf16((ushort*)szProcessName);

TCHAR szProcessName[4096] = {0};
//other code
QString  aaa = QString::fromUtf16((ushort*)szProcessName);

To copy to clipboard, switch view to plain text mode 

but aaa comes out empty!

Is it encoded in UTF-16?

Solved in this way

#ifdef Q_OS_WIN
#ifdef UNICODE
  aaa = QString::fromUtf16((ushort*)szProcessName);
  #else
  aaa = QString::fromLocal8Bit(szProcessName);
  #endif
  #endif

#ifdef Q_OS_WIN
#ifdef UNICODE
  aaa = QString::fromUtf16((ushort*)szProcessName);
  #else
  aaa = QString::fromLocal8Bit(szProcessName);
  #endif
  #endif

how can i change the LIBS things in make file?

[wysota]

You can't. You should modify the .pro file.
