Issue with string conversion

[Ogi]

Hi,

I've been writing a C++ program in QT on Ubuntu and it's working ok but as I am trialling Linux, I've just copied the files from my Ubuntu system to Linux Mint 14.

I've opened the project and it loads and can see all the files but when I come to compile, I get these strange compiler issues and am stuck!

I've got the following configured in my function:-

std::string strTemp;

QSqlQuery LoadOrders;
QString querystring(strSQL.c_str());
LoadOrders.prepare(querystring);
LoadOrders.exec();

Then, I want to put the results on my table:-

strTemp = LoadOrders.value("OrderCode").toString();

BUT, I'm getting

/home/backoffice/Source/MSC Front Desk/MSCFrontDesk/mainwindow.cpp:109: error: invalid conversion from 'const char*' to 'int' [-fpermissive]

/home/backoffice/Source/MSC Front Desk/MSCFrontDesk/mainwindow.cpp:109: error: no match for 'operator=' in 'strTemp = QVariant::toString() const()'

Now, I think this might have something to do with it but again, not sure!

/usr/include/qt4/QtSql/qsqlquery.h:89: error: initializing argument 1 of 'QVariant QSqlQuery::value(int) const' [-fpermissive]

Do you think there are fundamental differences with the qsqlquery libraries between Ubuntu and Mint?

Cheers for any pointers or help,
Carl.
