<![CDATA[Q_INT32 no such file or directory]]>Hello QT community,

I have this line of code that makes error on build:

#include <Q_INT32>

error is: Q_INT32 no such file or directory

What do I need to do?

It is a leftover from Qt 3. For Qt 4 and up, it is recommended to use qint32 instead.

And no, your include does not solve anything. It just makes your compile have an error before the one you're seeing if you do use qint32 instead.

After modifying code and adding #include <QtGloabal> I get this error:

QTextCodec::setCodecForCStrings(QTextCodec::codecForName("Windows-1250"));
QString strfile = QString::fromAscii(fileba);

I think that #include <Q_INT32> solves this error.

Just #include <QtGlobal> and use qint32. QtGlobal is included automatically by any other Qt include I think, but you can also include it explicitly.
