Re: [Interest] Qmake: Detecting if QSerialPort is installed
Hi Thiago,
This looks like the best solution. I already get a message when load()
fails*, and I can use it as test expression for conditional compile.
Maybe the wiki https://wiki.qt.io/Qt_Serial_Port
should be updated, as load() seems the best way to do it.
@Kai: QT_CONFIG seems to include everything Qt was build with, but
QtSerialPort is an "add-on" for Qt 4 that has to be build against the
installed Qt version.
Best regards,
Andre
* I don't fully memorize the message because I tested it on an other
computer.

Thats fine so far, but if QSerialPort is not installed for the
corresponding Qt4 version, I'd like to get a message during the qmake run.
What happens if, instead of that CONFIG += serialport, you write:
load(serialport)
?

... which will work for Qt 5. I missed that you asked about Qt 4, sorry about
that.
Does QT_CONFIG contain "serialport" in Qt 4?

You can use qtHaveModule() to check for a Qt module, and message(), error(),
warning() ... to print stuff.
!qtHaveModule(serialport): error(Qt SerialPort module not found)

[Interest] Qmake: Detecting if QSerialPort is installed
Hi all,
I'm working on a library that (optionally) depends on QSerialPort.
This library should also compile on Qt 4, so I did the following in the
project file:
greaterThan(QT_MAJOR_VERSION, 4) {
QT += serialport
} else {
CONFIG += serialport
}
Thats fine so far, but if QSerialPort is not installed for the
corresponding Qt4 version, I'd like to get a message during the qmake run.
What's the easiest way to do this with qmake?
Best regards,
Andre
