Using #ifdef with qt .pro
-
Hi All,
Sorry I realise this will be very easy, but I really can't work out what I'm doing wrong. Basically I'm converting some C++ code over to qt, I'm not that good with qt... In my c++ code I use #ifdef to output message grabbed from a tcp server. I only use these to test and debug. So in cpp file I use #ifdef and add the define to my makefile. In qt I've tried this but can get it to work, basically I've done
.cpp
[code]
int Client::Process_Server_Message( void )
{
int ret = 0;//
/is the server running/
/*/
if( message_string.find("Server Running") == 0 )
{#ifdef DEBUG_SERVER_MESSAGE
std::cout<<message_string<<std::endl;#endif
[/code]then in my .pro file I added the define
[code]QT += core gui
QT += network widgetsDEFINES += DEBUG_SERVER_MESSAGE
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
......
[/code]What do I need to added to my pro file to make the code inside #ifdef "appear". Thanks

Hi
try
DEFINES += "DEBUG_SERVER_MESSAGE=1"Also, as note: the
qDebug() << "stuff" << "more stuff";
(include QDebug first)
Is quite handy as its nothing in release builds and then no need for defines etc.note:
That worked for me with mingw. (gcc) if using VS, then maybe not. -

Thanks that worked :D I'm not using qdebug for this as I have a few different things I test for and don't want a load of information thrown at me at once. But thanks!
