cannot compile and install SerialPort library at Linux Mint 19.3

Guapo

Hi everyone

I tried to install Qt 5.12.4 from online installer at Linux Mint 19.3 and it´s not possible because there is no glibc 2.28 in this Mint Version.

I have another machine using Mint 19.3 without glibc 2.28 and the Qt 5.12.4 was install throught installer online a few years ago.

Yesterday I installed Qt from Mint repositories. It´s the only way to do this.

Now I need to install SerialPort library.

I found this tutorial: https://wiki.qt.io/Qt_Serial_Port

"The following are the recommended steps for building the QtSerialPort library for Qt4/Qt5 from the command line.

$ git clone git://code.qt.io/qt/qtserialport.git $ mkdir qtserialport-build $ cd qtserialport-build $ qmake ../qtserialport/qtserialport.pro"

But there isn´t any qtserialport.pro file.

I tried to compile with "examples.pro" and "serialport.pro".
Both of them with errors.

This is the qmake version used
qmake -version
QMake version 3.1
Using Qt version 5.9.5 in /usr/lib/x86_64-linux-gnu

The tutorial says that´s there is another way using qtcreator, but there isn´t sucessfull compilation.

What I´m doing wrong?

Thanks in advance

You should check out the Qt5.9 branch instead master

Hi,

By default when you clone the Qt repositories, they will be on the dev branch which is the current development branch and is targeting Qt 6. As @Christian-Ehrlicher wrote, the correct course of action is to checkout the branch that matches the version of Qt you want to build the module for.
